The Timken Company - Thrust Tapered Roller Bearings-Type TTHDFL-V-Flat

Batch CAD Cart (0) ▾

Consists of one thrust tapered race, one ﬂat race, rollers and cage.
Most sizes utilize pin-type cages with hardened pins through the center of the rollers, allowing closer roller spacing to maximize load capacity.
Smaller sizes have brass cages designed for unidirectional retention of rollers.
Combines the outstanding features of thrust tapered and cylindrical roller bearings to offer the highest possible load capacity of any thrust bearing of its size.
Originally developed for screwdown applications in metal rolling mills where high axial loads are common.
