High-speed precision angular contact ball bearing installation method


High-speed precision Angular Contact Ball Bearings are mainly used for high-speed rotating applications where the load is light and require high-precision, high-speed rotation, low-temperature vibration, and a certain service life. Often used as a pair of high-speed spindle support installation, is a key component of the internal surface grinder high-speed motor spindle.

Main Specifications:

1. Bearing Accuracy: Over GB/307.1-94P4 Accuracy

2. High speed performance indicator: dmN value 1.3~1.8x106/min

3. Service life (average): >1500h

The service life of high-speed precision angular contact Ball Bearings has a lot to do with the installation. The following items should be noted:

1. The bearing installation should be carried out in a dust-free and clean room. The bearing must be carefully matched. The bearing spacer must be ground. Under the premise of maintaining the height of the inner and outer rings, the spacer parallelism should be controlled at 1um. the following;

2. The bearing should be cleaned before installation. When the inner ring is sloped upwards during cleaning, the hand sensing is flexible and there is no sense of stagnation. After drying, put in the specified amount of grease. If it is an oil mist lubrication, put in a small amount of oil mist oil;

3. Bearings should be installed using special tools, uniform force, is strictly prohibited;

4. Bearing storage should be clean and ventilated, no corrosive gas, relative humidity no more than 65%, long-term storage should be regularly rust.
