Bearing rust not only happens in the process of bearing use, The production and storage of bearings are likely to rust. Therefore, rust prevention is a crucial process in the production of bearings.

Rust prevention of bearing parts before assembly:

Parts in the process of processing often with dust, moisture and acid fog and other atmospheric contact will occur rust, And the residual salt after heat treatment is not completely washed, pickling, acid printing liquid cleaning neutralization is not complete, demagnetization with grinding wheel, iron dust, hand sweat and so on are very easy to cause bearing rust. Therefore, to ensure that the workpiece will not cause losses in the process of processing, effective anti-rust measures should be taken for the Skate roller bearings parts that stay in the process.

1. The establishment of anti-rust library, the use of mechanical spray method, spray 2-3 times per shift, each time 10-15 minutes, bearing parts centralized anti-rust treatment.

2. Regular cleaning of various anti-rust equipment, strictly according to the process of preparation of anti-rust liquid, cleaning liquid, cooling water, regular testing, adjustment, replacement on schedule.

3. Bearing parts that need to be tested and ground should be demagnetized and cleaned with cleaning fluid before being stored for rust prevention.

4. After pickling, bearing parts must be cleaned, neutralized completely, and then treated with anti-rust water.

5. It is forbidden to wash hands and rags with cooling water and cleaning liquid to ensure the cleanliness and performance of the liquid and prolong the service life of the liquid.

Bearing product rust prevention:

Oiled anti-rust machine

1. Finished bearings coated with anti-rust oil and sealed packaging, can avoid the impact of atmospheric environment in the process of storage and transportation, rust and mildew, affect the performance.

2. Before kerosene spray washing and anti-rust lubrication oil spraying, filter elements that meet the process requirements should be used to ensure the cleanliness of finished bearings, and oil tanks and machine tools should be cleaned regularly.

3. When inspectors and assemblers touch finished parts and bearings, liquid gloves should be coated to avoid corrosion caused by hand sweat.

4. Handle the finished bearings carefully during handling and storage to avoid packing damage.

5. The assembly room and the storage room of finished bearings should be dry, clean and free from pollution sources.
