The accurate angle of SUNTHAI high speed is exposed to the method of erection of the ball bearing

The accurate angle of SUNTHAI high speed contacts the ball bearing, is used mainly in the high-speed rotation occasion lighter in load, require the bearing high-accuracy, high rotational speed, rise in low shaking and certain service life at low temperature. Often make the support in the electric basic shaft of high speed to install and use in pairs, it is key fittings in the electric basic shaft of high speed of grinding machine of interior surface.

Main technical indicator:

1.Three Thai bearing precision indexes: Exceed the precision of GB/307.1-94 P4 grade

2. High-speed performance index: DmN value 1.3~1.8x 106 / min

3. Life time Average : >1500 h

Three safe high speed accurate angles are exposed to the ball bearing life time and install very great relation, should pay attention to the following items

1. It should be dust proof that the bearing is installed, go on in the clean room, the bearing will pass the apolegamy meticulously, the bearing should be through grinding while using the space ring, on the premise of keeping the isometry of space ring of the Internal and external cycle, the parallelism of space ring should be controlled below 1um;

2. SUNTHAI bearing should be washed before installation, the inner circle slope is up while washing, hands are flexible in reaction, there is no sense of stagnating, after drying, put the oil of normal weight, the oil mist oil substantially as belonging to the oil fog lubrication and should put drib;

3. The installation of bearing should adopt the special tool, is forced evenly, forbid beating;

4. SUNTHAI bearing is preserved and should be cleaned and ventilated, without etchant gas, the relative humidity does not exceed 65%, keep and should antirust regularly for a long time
