Proper use and maintenance are the key to ensuring the accuracy and lifespan of bearings

Shandong Hangmu Precision Bearing Manufacturing Co., Ltd. specializes in the production of humanoid robot bearings, industrial robot bearings, cross roller bearings, four point angular contact bearings and other products, which are widely used in humanoid robots, industrial robots, automation equipment, medical instruments, radar and other fields. To help customers better use and maintain the company's products, the following maintenance points are compiled for reference.

1、 Installation points

Installation should be carried out in a clean, dry, and dust-free environment to prevent impurities from entering the interior of the bearing.

Before installation, check the mating surfaces of the shaft and bearing seat to ensure that there are no burrs, bumps, or rust.

Use specialized tools to apply force evenly and avoid directly tapping the bearing ring.

Please install bearings with directional requirements (such as cross roller bearings and four point angular contact bearings) correctly according to the instructions.

Bolt fixed bearings should be gradually and evenly tightened in diagonal order.

After installation, manually rotate and check for smooth operation, no abnormal noise or jamming.

2、 Lubrication management

Select the appropriate lubricant based on bearing type, speed, load, and operating conditions.

The recommended amount of lubricating grease filling is generally 30% to 50% of the internal space of the bearing.

Regularly replenish or replace lubricants to ensure good lubrication condition.

Pay attention to the cleanliness of the lubricant during filling to avoid mixing impurities.

3、 Daily use and maintenance

Regularly monitor the temperature, vibration, and noise of bearings, and promptly shut down for inspection if any abnormalities are found.

Avoid long-term overload operation to prevent track indentation and roller damage.

Take dust-proof and waterproof measures according to the working environment to prevent rust and wear.

For application scenarios with high precision requirements, the bearing rotation accuracy should be regularly checked.

4、 Disassembly and replacement

Use specialized tools during disassembly to avoid damaging the bearings by knocking or prying.

After disassembly, check the raceway, rollers, and cage for wear, indentation, and rust.

If there is a decrease in accuracy, abnormal noise, jamming, abnormal temperature, etc., it is recommended to replace it in a timely manner.

After replacement, reinstall and debug to confirm that the operating accuracy has returned to normal.
