High-speed angular contact ball bearings, mainly for the load lighter, high-speed rotating occasions, requiring bearing high-precision, high speed, low temperature rise low

vibration and the life of. Of ten for high-speed electric spindle bearing installed in pairs, the key component parts of the inner surface of the grinding machine of high speed

electric spindle.double row bearing
The main technical indicators:
A bearing accuracy of indicators: more than GB/307.1-94 P4 level precision
(2) high-speed performance: dmN value of 1.3 to 1.8x 106 / min.ball bearing suppliers
(3) life (average):> 1500 h
High-speed angular contact ball bearing service life and a great relationship, should note the following
A bearing installation should be clean, clean room, bearing carefully matching, bearing with every lap to go through the grind, the premise of maintaining the level of inside

and outside the ring spacers, spacer parallelism should be controlled in 1um the following;
Clean. Bea rings should be cleaned before installation, cleaning inner slopes upward, should be flexible and feel a sense of stagnation, dried, placed in a specified amount of

grease, such as in the case of oil mist lubrication should be placed in a small amount of oil mist of oil;ball bearing companies
Bearing installation should be used specialized tools, even by force, is strictly prohibited to beat;
Bearings shall be stored in clean air, corrosive gases, no more than 65% relative humidity, long-term storage should be periodically rust-proof.
