It is universally acknowledged that China NSF bearings is the autho rized SKF TQI  bearings agency in China, who has a broad range of SKF TQI bearings in stock, all of them are not only with high quality but also with competitive prices and best service.

Generally speaking, TQI bearings have two paired rows of rollers arranged back-to-back (fig). Their use is limited, being primarily where high stiffness is required and considerable tilting moments have to be accommodated. The bearings are generally mounted with an interference fit on the roll necks and therefo re often have a tapered bo re. The bearings are also used fo r the vertical rolls of universal mills; in this case the outer rings are mounted with an interference fit in the chocks and the inner rings have a loose fit on their seat.

Due to their limited application, only a few sizes and designs are produced by SKF. The designs described in the following and shown with pictures.

TQIN design
Bearing with two single row inner rings and one double row inner ring with roller and cage assemblies. Steel window-type cages and four single row outer rings (fig).

TQI design
Bearing with two single row inner rings and one double row inner ring with roller and cage assemblies. Steel window-type cages and two double row outer rings with an intermediate ring between them (fig).

TQI.1 design
Bearing with two single row inner rings and one double row inner ring with roller and cage assemblies. Pierced rollers and pin-type cages of steel. Two double row outer rings with an intermediate ring between them (fig).

TQIT design
Bearing with two single row inner rings and one double row inner ring with tapered bo re (taper 1:12 o r 1:30) with roller and cage assemblies. Steel window-type cages and two double row outer rings with an intermediate ring between them (fig). Bearings with a tapered bo re are used when an interference fit is required fo r the inner rings on the roll neck, e.g. when rolling speeds are high.
