The bearings are mainly used for lighter load high-speed rotation of occasions, the requirement of bearing high-precision, high-speed, low vibration low temperature rise and a certain life. Often support for high-speed electric spindle mounted in pairs, is a the inner surface grinder high-speed electric spindle critical spare parts.
Bearing life is installed, you should note the following:
Bearing installation should be clean, clean room, bearing carefully matching bearing spacer to go through the grinding, keep the contour of the premise of the inner and outer ring spacers, spacer parallelism should be controlled in 1um the following;
Bearings before installation should be cleaned, cleaning the inner slope upward, the handle should be flexible, with no sense of stagnation, dry, placed in the specified amount of grease, such as in the case of oil mist lubrication should be placed in a small amount of oil mist oil;
Bearings installed using specialized tools, even by force, non-beat;
Bearing store should clean ventilation, no corrosive gas, no more than 65% relative humidity, and long-term custody should be regularly antirust.
