25/5/2019· Roller thrust bearings, much like ball thrust bearings, handle thrust loads. The difference, however, lies in the amount of weight the bearing can handle: roller thrust bearings can support significantly larger amounts of thrust load, and are therefore found in car transmissions, where they are used to support helical gears.

16/6/2015· In main-shaft bearings, modular wind-turbine designs commonly use spherical-roller bearings (SRB) units that are more than 1m in diameter. Designers often select single SRB designs, one supported by a single main bearing and two torque arms that carry gearbox reaction loads. At least two factors contribute to early failures in main-shaft bearings.
