High speed precision Angle contact ball bearing, mainly for the load lighter high-speed rotating occasions, request bearing high accuracy, high speed, low temperature rise of low vibration and certain service life. Always do the high-speed electric spindle supporting a pair installation using high-speed inside surface grinding machine, is the electric spindle key accessories.
Its main technical indices:
1. Bearing accuracy index: more than GB / 307.1-94 P4 level precision
2. High-speed performance index: dmN value 1.3 ~ 180 x 106 / min
3. Usage life (on average) : > 1,500 h
High speed precision Angle contact ball bearing service life and installation has the very big relations, we should pay attention to the following matters
1. Bearing installation should clean the room in the clean, of bearing to carefully matching, bearing with every circle should pass grinding, in keep inside and outside every circle circle the premise, one-stop every lap parallelism should be controlled in 1um following;
2. Bearing before installation should be cleaned, when cleaning the circle of inner slope, hand induction flexible, no stagnation feeling, dry, add oil, plus specified amount after case of oil mist lubrication oil mist should be put in a small amount of oil;
3. Bearing installation should adopt special tool, stress even, forbidden knock;
4. Bearing should be stored clean and ventilated, non-corrosive gases, relative humidity, and no more than 65%, long-term preservation had shall periodically rust.
