It is well known that China BRG bearings is the authorized SKF TQI bearings agency in China, who has a broad range of SKF TQI bearings in stock, all of them are with high quality and competitive prices.
Frankly speaking, TQI bearings have two paired rows of rollers arranged back-to-back. 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 therefore often have a tapered bore. The bearings are also used for 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.
Because of 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.
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.
TQIT design

Steel window-type cages and two double row outer rings with an intermediate ring between them. Bearings with a tapered bore are used when an interference fit is required for the inner rings on the roll neck.
