Described inner ring and outer ring are all-in-one-piece four-point contact ball, and the installation step of described rolling element is as follows:
The first step, bearing outer ring and bearing inner race being positioned in approximately the same plane, the rib of bearing outer ring and the rib of bearing inner race locate laminating on one point；
Second step, connect step, rolling element is put into from two rightabout gaps, rib joint place and with the outer raceway contact on bearing outer ring；
3rd step, connecting step, in bearing inner race is pushed into it, raceway contacts with rolling element；
4th step, connect step, rolling element is uniformly distributed in the middle of the interior raceway of bearing inner race and the outer raceway of bearing outer ring；
5th step, connect step, one end of retainer band rolling element fixed bit is pressed into rolling element and completes trap.
Using technical scheme as above, the present invention has a superiority as described below:
A kind of inner ring of the present invention and outer ring are all-in-one-piece four-point contact ball, the present invention is by controlling at 186 °～193 ° by the ball angle φ that fills out of bearing outer ring and bearing inner race, then all-in-one-piece bearing outer ring and bearing inner race are used, eliminate the bonding process of bearing outer ring or bearing inner race, avoid the bonding precision impact on bearing accuracy, substantially increase processing and the efficiency of assembling of bearing, reduce percent defective, greatly reduce processing cost etc..
