skf comercial packaging

SKF bearings No Comments »

skf comercial packaging-A box may seem a simple and logical way of packing products such as bearings, but when SKF bearings needed a new packaging design for its SKF Explorer spherical roller bearings, it decided to go back to basics. It assembled a project team to identify what the requirements were for the design of a new packaging solution that could be used to pack a large number of bearing sizes, that could be used for automated packing and facilitated handling, that was environmental responsible and protected the contents and those handling the boxes and that had labelling that supported SKF’s strong brand values.
Following a review of its packaging for larger bearings, SKF decided to embark upon the development of an improved design that would meet demands for robustness, safety and recycling and would reflect the high quality of the contents.

Both customers and SKF staff were involved in the consultation process and first evaluations of a new packaging solution, the SKF ProofBox, which took place in Sweden in mid 2000. The design team developed a set of broad criteria for the new packaging that covered safety, environment, product protection, handling, production and branding.


The project was a learning curve for all concerned, with testing and refinement until a packaging solution was arrived at that could meet SKF’s strict criteria. The result has been the successful introduction of the SKF ProofBox, which can be used to pack and ship 45 different bearing sizes on automated packing lines.


The design needed to take into account movement and storage, including the ability to transport the package using a forklift truck, to load it efficiently on a half pallet, and to stack packages both symmetrically and asymmetrically. It had to be possible for the bearing to be safely lifted out of the packaging by using, for example, a lifting strap.

The packaging needed to clearly show whether someone had opened it, and it had to be difficult to re-seal. The solution was a box divided horizontally into two halves in the middle. These halves overlap and the slit is sealed with tape. The tape cannot be removed without it being destroyed. To make it even more difficult for an unauthorized person to open the packaging, the product labels were placed across the tape. To make sure that the packaging could not be opened unintentionally, four straps were placed crosswise around the packaging.

With the new packaging it was envisaged that a packaging line with robots could be introduced. When samples became avail-able, it was possible to prepare production for the introduction of the new packaging.

Before the SKF ProofBox was launched, an intensive test programme was initiated:

Rust protection in climate chamber.
Transportation tests (truck, train, boat and aeroplane).
Loading tests.
ASTM handling tests by external packaging and transportation institute.

The success of the SKF ProofBox can be attributed to the fact that SKF set up a project group at an early stage and brought

in expertise from different sectors, adding creativity to the process. SKF invested in tools to test whether the packaging idea functioned in reality. With the aid of the sample packaging, all the weaknesses could be traced and rectified before costly investments were made.

The SKF ProofBox is design protected in most industrial countries.

fag transmission bearing

FAG bearings No Comments »

fag transmission bearing are designed to offer a high degree of passenger comfort, generate little noise and be economical. This is made possible, amongst other things, by the rolling bearings developed by Schaeffler Group (FAG bearings)Industrial that can be found in railway transmissions.

fag transmission bearing consists of Various ball and roller bearing types  mentioned below, further types such as deep groove ball bearings, spherical roller bearings, and angular contact ball bearings are used.

Cylindrical roller bearings
Cylindrical roller bearing with a one-piece solid brass cage
Single-row cylindrical roller bearings offer an advantage over other conventional bearing designs because of how easy they are to dismantle in the inner and outer rings with a roller and cage assembly. This means that the user is offered practical benefits with regards to assembly, dismantling, maintenance and inspection. Cylindrical roller bearings are particularly suitable for transmitting high radial forces. NJ and NUP cylindrical roller bearings can also partly be used for transmitting axial forces. FAG cylindrical roller bearings have a modified linear contact between the rollers and the raceway to prevent edge stresses.

Tapered roller bearings

Tapered roller bearings are can be taken apart, since the inner ring with the roller and cage assembly and the outer ring can be assembled separately. The modified linear contact between the rollers and the raceways prevent edge stresses. Tapered roller bearings can support high radial and axial loads. Since the bearings can only support axial loads in one direction, as well as for supporting internal aligning forces, a second laterally-reversed tapered roller bearing is required for counterstay.

Four-point contact ball bearings

Four-point contact ball bearings are a type of single-row angular contact ball bearing, since they support high axial loads in both directions. Four-point contact ball bearings are usually assembled with cylindrical roller bearings in a loose radial location. Axial minimum loads are required for low friction, especially for high speeds.
The inner ring of a four-point contact ball bearing is split, which means it can accommodate a large number of balls.

nsk bearing catalogue

NSK bearings 7 Comments »

nsk bearing catalogue come in all sizes, fit to meet the needs of the smallest applications like dental handpieces to the large bearings in a steel mill.

Ball Bearings


NSK ball bearings will accomodate moderate to heavy radial loads and low to moderate thrust loads in either direction.  There are multiple types in order to suit specific application requirements.

Deep groove radial bearings are manufactured as open bearings or with shields or seals. 
Max Type bearings are used in applications involving heavy radial loads and low speeds where thrust loads are comparitively low. 

Double row bearings are used in applications where there are high radial loads and axial loads in both directions. 

Self-Aligning bearings allow for misalignment of the shaft and housing.  They are manufactured with two rows of balls and one continuous spherical raceway in the outer ring. Mast Guide bearings have a high load capacity and are specifically designed for use in fork lift trucks. 

Integral shaft bearings, or “water pump bearings”, are largely used in automotive markets.  They do not require an inner ring, and feature double lip seals to prevent contamination.  
Angular contact bearings are used where radial and thrust loads are combined in the same application. 

Cylindrical Roller Bearings

NSK Cylindrical Roller bearings are designed to carry heavy loads and are suitable for high speed applications.  Their rolling elements are ground to provide maximum contact with the raceway and are precisely crowned to avoid edge loading due to shaft misalignment.

Spherical Roller Bearings

NSK Spherical Roller bearings are double row self-aligning bearings capable of carrying heavy radial loads combined with moderate thrust loads in either direction.  Spherical roller bearings are extremely resistant to shock loads and their self-aligning feature allows full capacity loading despite shaft deflection.

Shaker screen spherical roller bearings are designed to accomodate high loads, static and dynamic misalignment, and severe environmental conditions inherent in vibrating applications such as screens, feeders, and compactors.

Triple ring bearings are specially designed for use with controlled crown rolls used extensively in the paper industry.  These high load capacity bearings provide “shaft within shaft” operation, while simplifying the surrounding structure and installation.

Tapered Roller Bearings

NSK Tapered roller bearings are designed to take combined heavy radial loads and heavy radial thrust loads in one direction while operating at moderate speeds.  Both metric and inch tapers are offered with the only difference being the dimensions of the measure for the bearings.

NSK’s patented HR High Capacity metric tapers offer additional capacity within the same boundary dimensions and are interchangeable with standard metric tapered roller bearings.

Throughout our website you will find information on products and ctalogues to help you with your selection process.  In addition, we have application engineers available to help you with your selection process.

fag skf full complement cylindrical roller bearings

FAG bearings, SKF bearings No Comments »

 fag skf Full complement cylindrical roller bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads. However, they cannot operate at the same high speeds as caged design cylindrical roller bearings

 fag skf Full complement cylindrical roller bearings consist of Single row full complement cylindrical roller bearings and Double row full complement cylindrical roller bearings

skf  Single row full complement cylindrical roller bearings

NCF design bearings  have two integral flanges on the inner ring and one integral flange on the outer ring and can thus support axial loads acting in one direction and provide axial shaft location in one direction. A retaining ring at the flangeless side of the outer ring holds the bearing assembly together. The axial internal clearance in the bearing is provided in the product table and is designed to permit small axial displacements of the shaft in relation to the housing, e.g. as a result of thermal expansion of the shaft, to be accommodated in the bearing.

NJG design bearings comprise the heavy dimension series 23 and are intended for very heavily loaded, slow speed applications. These bearings have two integral flanges on the outer ring and one integral flange on the inner ring and can thus support axial loads acting in one direction and provide axial shaft location in one direction. In contrast to the other full complement bearing designs, NJG design bearings have a self-retaining roller complement. The outer ring with its two integral flanges together with the roller complement can therefore be withdrawn from the inner ring, without having to take any precautions to prevent the rollers from falling out .

fag  Single row full complement cylindrical roller bearings

includes series of  SL1818  SL1822  SL1829  SL1830  SL1850  SL1923.

skf Double row full complement cylindrical roller bearings

NNCL design bearings  have an inner ring with three integral flanges and a flangeless outer ring. A retaining ring, inserted in the outer ring between the roller rows, keeps all bearing components together. Axial displacement of the shaft relative to the housing in both directions can be accommodated within the bearing. The bearings are therefore suitable for non-locating bearing positions.

NNCF design bearings  have three integral flanges on the inner ring and one integral flange on the outer ring enabling the bearing to provide axial location for a shaft in one direction. A retaining ring is inserted in the outer ring at the side opposite the integral flange and serves to hold the bearing together.

NNC design bearings  are equipped with the same inner ring as bearings of the NNCL and NNCF design. The outer ring is split and held together by retaining elements, which should not be loaded axially. Both parts of the outer ring are identical and carry one integral flange, enabling the bearing to locate the shaft axially in both directions.

NNF design bearings in the NNF 50 and 3194(00) series are always sealed on both sides and filled with grease. The two-piece inner ring has three integral flanges and is held together by a retaining ring. The outer ring has an integral central flange. The bearings can be used to locate a shaft axially in both directions. Because of the large distance between the two rows of rollers, the bearings are also able to accommodate tilting moments.

skf bearing in supply of green energy for Beijing’s 2008 Olympic Games

SKF bearings No Comments »

When the leading Chinese wind turbine company Goldwind was awarded the contract to supply 33 turbines for the 2008 Beijing Olympic Games, the company selected SKF as the bearing supplier for this prestigious project.

The 1.5 MW turbines are Goldwind’s largest turbines and, like all OEM’s, Goldwind knew that the larger the turbine the more they need to be sure about the reliability of critical components like bearings. That is because turbines producing higher energy outputs are usually physically bigger and taller than smaller energy-producing units. And that results in more wind being captured, which leads to higher forces on machinery at the top of the turbine where the electricity is generated,. In the case of Goldwind’s 1.5 MW turbines, that is 65 metres from the ground.

In choosing SKF, the Goldwind company based its decision on a good history of co-operation with SKF on smaller turbines, but also the fact that SKF had supplied bearings for many bigger turbines around the world, including the biggest in the world at that time; Repower’s 5 MW turbine that was designed for the extremely tough environment of offshore wind energy generation.

Mrs. Qiaozhen Ning, director of mechanical design at Goldwind, said “we are very happy to select SKF for this project because we know from experience that they understand the application demands of wind turbines, and the technical support we get from the engineers in SKF China is excellent.”

The 1.5 MW design is a direct drive turbine requiring no gearbox, but the turbine mainshaft — to which the blades and rotor are connected — must be supported by bearings to allow the blades and rotor to rotate in order to produce electricity.

The bearings selected for the 1.5 MW turbines are a single-row cylindrical bearing, almost 1 metre outside diameter, and a double-row tapered roller bearing, almost 600 mm outside diameter.

SKF calculations show that both bearings have sufficient capacity and design features to operate reliably in the expected range of weather conditions to be encountered during the Games but also for many years after the Games are finished, when the electricity generated will supply ‘green’ power to the city of Beijing. The turbines are all erected and many are already producing power.

Since the contract was awarded to Goldwind another 10 turbines have been ordered. The 43 turbines now constitute a wind farm on the banks of the Guanting reservoir in Beijing. These turbines are part of the increasing use of wind power in China and will probably be seen by millions around the world as television reports of the Olympic rowing event, that takes place on the Guanting reservoir, are broadcast in August 2008.
