1. Service life (even): >1500 h
2, bearing accuracy target: beyond GB/307. 1-94 P4 level accuracy 3, high-speed performance target: dmN value 1. 3~1. 8x 106 / min
The service life of the high-speed fine-angle touch ball bearing is properly close to the device; the following matters should be paid attention to: 1. The bearing device should be cleaned before cleaning; when the inner ring slope is upward; the hand is sensitive; there is no blockage; after drying; Put a specified amount of oil; if it is smooth, put a small amount of oil mist oil,
2, bearing storage should be sanitary ventilation; no corrosive gas; relative humidity does not exceed 65%; long-term storage should be regularly rust-proof.
3, the bearing device should be in the dust-free; clean room; the bearing should be carefully selected; the bearing spacer should pass the grinding; under the premise of insisting the inner and outer ring spacers; the parallelism of the spacer should be controlled at 1um the following,
4, the bearing device should use special things; even force; no hit,
