High-speed fine-angle touch ball bearing; it is mainly used for high-speed rotating occasions with light load; high-precision bearing, high-speed, low-temperature low-rise oscillation and inevitable service life. It is often used as a support device for high-speed electric spindles. The key components of the high-speed electric spindle of the internal and external surface grinder. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Primary technical goals:
1. Bearing accuracy target: Beyond GB/307. 1-94 P4 accuracy 2. High-speed performance target: dmN value 1. 3~1. 8x 106 /min
3. Service life (even): >1500 h
The service life of high-speed fine-angle touch ball bearings has a lot to do with the device; the following matters should be emphasized1. The bearing device should be carried out in a dust-free and clean room; the bearing should be carefully selected; the spacer for the bearing should be ground; under the premise of maintaining the height of the inner and outer ring spacers; the parallelism of the spacer should be controlled below 1um.
2. The bearing device should be cleaned before cleaning; when the inner ring slope is facing upwards; the hand is sensitive; there is no blockage; after drying; put a specified amount of oil; if the oil mist is smooth, a small amount of oil mist oil should be placed.
3. The bearing device should use special things; the force is even; the hitting is prohibited.
4. Bearing storage should be hygienic and ventilated; no corrosive gas; relative humidity should not exceed 65%; long-term storage should be regularly rust-proof.
