In addition to the excellent quality, bearings are also very precise parts. They are high-performance bearings. If they are used improperly during use, they will not only fail to achieve the expected performance effects, but also easily damage the bearings. In terms of lubrication, everyone must have already Notice. In addition to lubrication, what other aspects need to be paid attention to during the use of bearings?

1. Be careful when using and installing

Strong stamping is not allowed, the bearing is not allowed to be hit directly with a hammer, and pressure is not allowed to be transmitted through the rolling elements.

2. Use appropriate and accurate installation tools

Use special tools whenever possible, and try to avoid things like cloth and short fibers.

3. Try to keep the bearing and its surrounding environment clean

Even invisible dust entering the bearing can increase bearing wear, vibration and noise.

4. Prevent bearing corrosion

When taking the bearing directly by hand, fully wash off the sweat on the hand, and apply high-quality mineral oil before operating, especially in the rainy season and summer, pay special attention to rust prevention.

Under certain special operating conditions, the bearing life can be obtained longer than the traditional calculation, especially in the case of light load. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricating film and limit contamination that may cause surface damage. In fact, under ideal conditions, so-called permanent bearing life is possible.

When disassembling the bearing for inspection, first record the appearance of the bearing, confirm the residual amount of lubricant, and wash the bearing after sampling the lubricant for inspection. As the cleaning agent, gasoline and kerosene are generally used.

The cleaning of the removed bearing is divided into coarse cleaning and fine cleaning, which are placed in the container respectively, and the bottom of the metal mesh is placed first, so that the bearing does not directly contact the dirt of the container. During rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing, so be careful. In the rough cleaning oil, use a brush to remove grease and adhesions. After it is roughly clean, transfer to the fine cleaning.

Fine cleaning is to carefully clean the bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.

Bearing maintenance and judgment: In order to judge whether the disassembled bearing can be used, it should be checked after the bearing is cleaned. Check the condition of raceway surface, rolling surface, mating surface, wear of cage, increase in bearing clearance, and damage and abnormality irrelevant to the decrease of dimensional accuracy. For non-separable small ball bearings, use one hand to support the inner ring horizontally, and rotate the outer ring to check whether it is smooth. For separable bearings such as tapered roller bearings, the rolling elements and the raceway surface of the outer ring can be inspected separately.
