Do not hammer the bearing end face and non-stressed surface directly during installation. Use a pressure block, sleeve or other installation tools to make the bearing evenly stressed. Do not install it by transmitting force through the rolling element. If the installation surface is coated with lubricating oil, the installation will be smoother. If the interference fit is large, the bearing should be placed in mineral oil and heated to 80~90℃ and installed as soon as possible. The oil temperature should be strictly controlled not to exceed 100℃ to prevent the tempering effect from reducing the hardness and affecting the size recovery. When disassembly is difficult, it is recommended that you use the disassembly tool to pull outward while carefully pouring hot oil on the inner ring. The heat will cause the inner ring of the bearing to expand, making it easier to fall off.

Not all bearings require the minimum working clearance. You must choose the appropriate clearance according to the conditions. In the national standard 4604-93, the radial clearance of rolling bearings is divided into five groups - group 2, group 0, group 3, group 4, and group 5. The clearance values are from small to large, among which group 0 is the standard clearance. The basic radial clearance group is suitable for general operating conditions, normal temperatures and commonly used interference fits; large radial clearances are suitable for bearings working under special conditions such as high temperature, high speed, low noise and low friction; small radial clearances are suitable for precision spindles, machine tool spindle bearings, etc.; a small amount of working clearance can be maintained for roller bearings. In addition, there is no clearance for separate bearings; finally, the working clearance of the bearing after installation is smaller than the original clearance before installation, because the bearing has to withstand a certain load rotation, as well as the elastic deformation caused by the bearing fit and load.

For the sealing defect problem of the embedded sealed bearing, there are two steps that need to be strictly carried out during the adjustment process.

1. The cover structure of the embedded sealed bearing is changed to both sides of the bearing, and the adjustment is made from the equipment bearing installation structure. It does not need to be in direct contact with the bearing, and the bearing is dust-proofed from the outside of the bearing. The sealing effect of this structure is higher than the self-seal of the bearing sold by the bearing agent, which directly blocks the invasion path of granular matter and ensures the cleanliness of the inside of the bearing. This structure increases the heat dissipation space of the bearing and has less damage to the fatigue resistance of the bearing.

2. Although the external sealing method of the bearing has a good sealing effect, the heat dissipation path is also blocked, so a cooling component needs to be installed. The cooling device can reduce the operating temperature of the lubricant, and after cooling, the heat can be naturally dissipated to avoid high-temperature operation of the bearing.
