81215 high precision cylindrical roller bearing

Thrust roller bearings are used to bear the axial extension and radial joint transformation of the main shaft, but the length shall not exceed 55% of its length. 29000 type bearings are subdivided into asymmetric spherical rollers, which can be inserted into the rollers to slide relative to the raceway during operation. The rollers are long, large in diameter, and have a large number of rollers. When designing and selecting models, you should give priority to selection; 80000 type thrust cylindrical roller bearings, 90000 type thrust tapered roller bearings, AXK type thrust needle roller bearings,,,,, large capacity, usually lubricated with oil, some can be used at low speed Grease. It can withstand one-way axial displacement, which is much larger than the axial displacement of thrust ball bearings, and has high rigidity and takes up little insertion space. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for smaller occasions, and the axial direction of thrust tapered roller bearings is slightly higher than that of thrust cylinders
