Tapered roller bearing TQIT

four-rowsteelhigh-speed

TQIT (Tapered Bore Four-Row Assembly) Type TQIT bearings have a tapered bore that is matched and continuous through the inner races. This allows for an interference fit on the backup rolls of high-speed mills, where a loose inner race fit of a straight bore bearing could cause excessive neck wear. The indirect mounting of the bearing pairs increases the overall effective spread of the bearing, providing optimum stability and roll rigidity.
