How to do regular maintenance after rolling bearing installation

Commonly used installation tools for rolling bearings are hand hammers, copper rods, sleeves, special pads, screw-mosquito fixtures, presses, etc. The amount has vernier calipers, micrometers, dial gauges, etc., but different tools should be selected according to different bearing models.

After selecting the correct tool, the bearing can be installed. Pay attention to the presence of no bumps, rust layer, wear debris, sand, dust and dirt. If it is, it will cause installation difficulties and must be kept imported. The surface of the bearing assembly and the mating parts are clean.

In addition to the surface of the rolling bearing assembly and the matching of the surface of the part to be cleaned, pay attention to the rust layer of the journal, the surface of the housing hole, the shoulder end face, and the connecting parts such as bushings, washers, and end caps. If you have one, you can use a fine cloth, light sanding, and then install.
1. In terms of bearing speed, the bearing is determined according to the type, size, accuracy, cage type, load, lubrication method, and cooling method of the bearing.
2. The installation and disassembly of the bearing need to be disassembled and installed frequently in specific applications to ensure that it can be inspected and repaired according to its location. Bearings that can be installed separately for the inner and outer rings, such as cylindrical bearings, needle bearings, and tapered bearings, are well suited for this application. The tapered self-aligning ball bearing and self-aligning roller bearing also simplify the installation procedure with the help of the bushing.
3. In some cases, the rolling bearing should be pre-stressed to increase the rigidity. This procedure is usually used for deep groove ball bearings, radial thrust ball bearings and tapered roller bearing inner and outer ring offsets, shaft bending, shaft or bearing housing tolerance changes. Mismatching will lead to eccentricity of the inner and outer rings. In order to prevent the eccentric angle from being too large, automatic self-aligning ball bearings, self-aligning roller bearings, or self-aligning bearing seats are preferred choices.嗓 Audio frequency and torque, dynamic bearings are produced according to high-precision scale, so the sound and torque are small. Deep groove ball bearings and cylindrical roller bearings are used in combination for low noise and low torque.
