Thrust roller bearings are used for carrying the combined loads basically on axial loads, but the radial roads should not heavier than 55% of the axial loads. Compared with other thrust roller
bearings, needle roller thrust bearings have lower friction and higher speed. They are self-aligning. The rollers of the 29000 type is unsymmetrical spherical rollers, which will reduce the slide
rollers relative to raceway during operation. The rollers are long and with long diameter. The quantity of the rollers is large, and the carrying capacity of the roller is also large, so they can be
lubricated by oil or grease in individual low speed operation.. They are your first choise;80000 type cylindrical roller beaings , 90000 type tapered roller bearings and AKK type needle roller thrust bearings all can carry much heavier axial load in a directon than Thrust
ball bearings, and they have great rigidity but occupys less space. Cylindrical roller thrust bearings and needle roller thrust bearings apply to the low speed operation, and tapered roller
thrust bearings can operate in a little higher speed situation.
