Composed of radial needle roller bearings and cylindrical roller thrust bearings
Composed of cylindrical roller and cage thrust assembly.
Delivered without inner ring
Can be combined with inner rings in applications where the shaft cannot be hardened and ground
Can withstand axial load in one direction
Axis can only be positioned in one direction
Can be mounted back-to-back on short shafts and where changes in length due to thermal expansion are relatively small
For these types of configurations, cup spring preloading of thrust ball bearings is recommended. If one of the thrust bearings is unloaded, the elastic preload helps prevent the steel balls from sliding. Preloading also improves thrust ball bearing performance and reduces noise levels.
