High-speed precision angular contact ball bearings
2013-11-14 by seoer4
High-speed precision angular contact ball bearings , mainly used for high-speed rotating occasions lighter loads , requiring high precision bearings , high speed, low vibration and low temperature rise a certain life . Often high-speed spindle support member installed in pairs , is the inner surface grinding spindle speed key component parts .
The main technical indicators:
1 bearing precision index : Over GB/307.1-94P4 level precision
2 high-speed performance: dmN value 1.3 ~ 1.8x106/min
3 life ( average ):> 1500h
High-speed precision angular contact ball bearing service life of a great relationship with the installation , you should note the following:
1 bearing installation should be clean , clean surface profile measurement room for the bearing to be carefully matching, bearing spacers to go through the grind of maintaining high inner and outer ring spacers under the premise of the spacer should be controlled in parallel 1um the following ;
(2) Before installing the bearings should be cleaned , cleaning the inner slope upward , feel Wind turbine bearing should be flexible , no sense of stagnation , dried , placed in a predetermined amount grease, oil mist lubrication should be placed in the case of a small amount of oil mist ;
3 bearing installation tool should be used exclusively , even by force , is strictly prohibited beat ;
4 bearing deposit should be clean and ventilated , non-corrosive gases, relative humidity less than 65% , long-term storage should be periodically rust.
