The Timken Company - Thrust Tapered Roller Bearings-Type TTHDFLSA - Compare Items

Batch CAD Cart (0) ▾

Same basic roller and raceway design as the TTHDFL, except that the lower race is composed of two pieces whose faces are spherically ground to permit self-alignment under conditions of initial misalignment.
TTHDFLSA bearings should not be used if dynamic misalignment (changing under load) is expected.
