Chrome Steel Cylindrical Ball Bearing High Speed Long Working Life​

81252-M bearing Features,

1. The processing quality of the surface, the end face of the shoulder, the groove and the connecting surface, check the inner diameter of the 81252-M inner ring that has been used, and ensure that it has a sufficient interference fit with the axle.

2. If the size and condition of the shaft meet the requirements, but The measured axial clearance is less than 0.025mm, and can not rotate 81252-M freely by hand.

3. When the 81252-M combination slides down to the guide sleeve and the hard paper partition has popped up, the outer seal seat should be supported to prevent the bearing Shedding from the seal, you can not simply use some of the

4. Wheel frames used to transport sliding bearings, because the adjacent wheel rim will contact and damage the bearing combination.

5. When you find the above odor or smoke, you should stop immediately to find the overheated bearing, and Check and determine the cause and precautions of overheating before the equipment is operated again.

6. This types bearing can accmmodate axial load in one direction and thuslocate a shaft axailly in one direction, they must not be subjected to any radial load.

Spherical roller thrust bearings are featured by the extremely big axial load carrying capacity and meanwhile they can also carry cetrain radial load.
