1、Correct handling and storage

In order to avoid contaminants including moisture, dust or dirt from entering the bearings, the bearings should be handled and stored correctly. First of all, the bearings should be placed horizontally in a clean, dry and room temperature environment under the original packaging; do not store with chemical products in the same warehouse, the relative humidity of the warehouse should not exceed 65%; the bearings can not be stored on the ground; not installed before the use of the package is not prematurely removed, otherwise the bearings may be exposed to corrosion or contaminants. Bearing for precision parts, should be handled with care to avoid bumping, components fall, etc., which may lead to premature failure of the bearing 2, mounting, dismounting the use of professional tools, handling bearings using appropriate equipment in the bearing mounting and dismounting process in order to ensure that the force is uniform, the need to use special tools, such as: bearing puller or induction heater. The use of special tools, please refer to the instructions and precautions, such as the need to use the heater mounted bearings, the temperature should be strictly controlled below 120 ℃; dismantling the use of puller need to specify the use of methods and precautions.

3、Before mounting the bearings, the physical condition of the shaft or bearing housing should be checked carefully.

Familiarize yourself with the correct installation method, use a soft cloth to wipe the surface before installation (wipe cloth can't be replaced by old cotton wool, etc.).

4、Correct installation

When mounting bearings, the correct method should be used, the specific method depends on the type of bearing and the type of fit. Radial ball bearing rings can be mounted with various fits, from clearance fit to interference fit, depending on the type of load, speed and vibration level. It is important that the pressure applied during mounting is in the correct position, otherwise damage to the rolling elements may result.

5、Correct lubrication

One of the main causes of bearing failure is lubrication. Including the use of incorrect lubricant, and the use of too much or too little lubricant. Need to consider the environmental conditions, temperature, speed and load conditions to select the correct lubricant, filling volume and lubrication.

6, avoid the use of temperature out of range

The operating temperature of the bearing should be within the designed limit temperature range, otherwise long time work, will lead to reduced load carrying capacity, bearing early failure. In addition, during regular maintenance, need to pay attention to the ring, rolling body and keep frame discoloration, because this may indicate overheating, may be due to high operating temperature or lubrication caused by improper, must pay attention.

7, as far as possible to avoid corrosion

Bearing corrosion is a common form of damage, bearing exposure in a humid environment, may lead to moisture intrusion, causing bearing corrosion, ultimately leading to premature bearing failure. In specializing in corrosive environmental applications, the selection of suitable bearings is the key, the need to choose different materials and sealing forms for bearing design.

8. Carefully select alternatives

If the bearings do reach the end of their service life, replace them with bearings of the same or higher quality than the original bearings. In the long run, low quality substitutes may lead to greater losses.

9. Monitoring

Bearings rarely fail without any warning signs. Excessive noise, vibration, and temperature rise can all be signs of deeper problems. If a bearing shows any abnormal operating conditions, it should be monitored more closely and the cause should be found.

10, seek professional help

Bearing professionals can provide better maintenance methods and recommendations for your specific application, and can help you diagnose bearing problems. If in doubt, seek professional help.
