These thrust roller bearings have raceways that are perpendicular to the shaft, allowing them to withstand high axial, or thrust, loads (where the load is parallel to the shaft) in one direction. Because they cannot support radial loads (where the load is perpendicular to the shaft), thrust roller bearings are a good choice for applications where shaft misalignment is unlikely.
Roller bearings use cylindrical rolling elements that distribute loads over a wide surface area, which allows roller bearings to tolerate higher loads than ball bearings. To ensure proper functioning, bearings should be lubricated regularly.
Compact Needle Roller Bearings
Consisting of needle rolling elements in a cage, these bearings offer the lowest profile possible for a thrust bearing. Use them when the surface of the housing face is hard enough to serve as a raceway.
Heavy Duty Cylindrical Roller Bearings
These bearings have a higher load capacity than needle roller bearings with the same outside diameter.
Raceways for Needle Roller Bearings
Also known as thrust washers, raceways are used with needle roller bearings when the housing face is too soft to serve as a raceway.
