1. Cleaning: Cross roller bearings should be cleaned before assembly. Carefully clean the bearings, main shafts, bearing seats and other installation parts to remove rust-proof oil or impurities from the factory. At the same time, determine whether there are burrs or burrs on the bearing installation parts.
2. Load the bearing: Load the bearing into the bearing seat and keep it level during installation. At the same time, in order to avoid tilting, the bearing should be kept level. The other side should be knocked evenly with a plastic hammer, and the bearing should be loaded into the bearing seat little by little. In the inside, it can be confirmed by sound whether the reference plane is all close.
3. Fixed flange
(1) Place the fixed flange on the cross roller bearing and shake the fixed flange several times to make the position of the bearing and the bolt hole match.
(2) When the fixing bolt is inserted into the hole and the bolt is turned by hand, make sure that the bolt is not difficult to screw in due to the deviation of the bolt hole.
(3) The locking of the fixing bolts is not all locked to all locked. Generally, it is gradually locked in 3-4 stages. Tighten it repeatedly in the order of diagonal lines. When tightening the inner ring and outer ring, turn the overall inner ring or outer ring slightly to correct the deviation between the main body and the inner and outer rings.
