Installation skills of angular contact ball bearings
- Aug 01, 2017 -

High-speed precision angular contact ball bearings are mainly used for high-speed rotating occasions with lighter loads, requiring high precision, high rotational speed, low temperature rise vibration and a certain service life. Often used as the supporting parts of high speed electric spindle, it is the key accessory for the high speed electric spindle of inner surface grinder.

Main Technical Index:

1. Bearing accuracy index: More than gb/307.1-94 P4 Level Precision

2. High-speed Performance index: DMN value 1.3~1.8x 106/min

3. Service life (average): >1500 h

The service life of high speed precision angular contact ball bearing has much to do with the installation, the following matters should be noted

1. Bearing installation should be in the dust-free, clean room, bearing to undergo careful selection, bearing with the ring to be grinding, in order to maintain the inner and outer ring, and so on the premise that the parallel degree of the loop should be controlled below 1um;

2. Bearing should be clean before the installation, cleaning, the inner circle of the slope upward, feel flexible, no sense of stagnation, after drying, put in the prescribed amount of grease, such as oil mist lubrication should be put into a small amount of oil mist oil;

3. Bearing installation should be used special tools, uniform force, strictly prohibit beating;

4. Bearing storage should be clean and ventilated, non-corrosive gas, relative humidity of not more than 65%, long-term preservation should be regularly anti-rust.
