When high axial load capacities are needed and envelope space is minimal, thrust needle roller bearings are an option. These bearings consist of a stamped or machined cage and rollers. The cage retaining the rollers is paired with thrust washers that act as raceways. Thrust bearings can be used without thrust washers when the faces of adjacent machine components can serve as raceways, allowing the machine to be even more compact. These bearings provide a high degree of stiffness and are most suitable where high accuracy is required at high speeds and under fluctuating heavy loads, such as machine tools and high-pressure pumps.
LILY bearing washers are required in cases where adjacent machine components cannot serve as raceways. washers are developed primarily for applications with cylindrical roller and cage thrust assemblies, but they can also be combined with needle roller and cage thrust assemblies. These washers, made of carbon chromium bearing steel are hardened and have precision machined raceways.
