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