NTN Spherical roller thrust bearing 29412
 

There are many types of thrust bearings: single direction thrust ball bearing, needle roller thrust bearings, cylindrical roller bearings, spherical roller bearings. This kind of bearings are designed primarily to support axial loads at contact angles between 30 and 90 degree. Just as with radial bearings, these bearings are different according to the type of rolling element. As we know, thrust ball bearings use the balls as the element and thrust roller bearings use the rollers. With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping movement between the bearings rolling elements and raceways.

NTN Spherical roller thrust bearings 29412 have self-aligning properties, because this king of bearings incorporate barrel-shaped rollers as rolling elemengts. Just like spherical roller bearings, spherica roller thrust bearings have a special characteristics: the center of the spherical surface for spherical roller thrust bearings is the point where the raceway surface of the housing raceway washer meets the center axis of the bearing.
