Bearing instructions:
1. The main reasons for fracture failure of thin-wall cross roller bearing are defect and overload. When the applied load exceeds the strength limit of the material, resulting in the fracture of the part is called overload fracture. The main reason of overload is the sudden failure of main engine or improper installation.
2. The defects of bearing parts, such as microcracks, shrinkage holes, bubbles, large foreign sundries, overheating tissues and local burns, will also cause fracture at the defect when impact overload or severe vibration, which is called defect fracture.
3. It should be pointed out that in the bearing manufacturing process, the re-inspection of raw materials into the factory, the quality control of forging and heat treatment, and the control of the processing process can be correctly analyzed through the instrument whether the above defects exist, and the control should be strengthened in the future.
4. But generally speaking, the bearing fracture failure usually occurs, most of which are overload failure.

How to repair worn cross roller bearings:
1, the bearing surface treatment, such as the use of sandpaper grinding surface, and anhydrous ethanol cleaning, the purpose is to accumulate on the surface of the bearing seat some oil, impurities, moisture and other treatment clean.
2, ready to use the repair materials, we are generally based on the wear of the bearing bottom to repair the material to reconcile.
3, daub material, mainly refers to the piston rod material has been deployed evenly daub in the bearing to be repaired parts, and to ensure that the solid filling.
4, Wait for a period of time until the material coated on the bearing surface is fully cured. Of course, in the curing process, we can properly heat the material to speed up the curing. The heating temperature should be controlled.
5,Check the specific repair situation to see if it can meet the requirements of use.
Notes for bearing disassembly and installation:
Disassembly steps and precautions:
1. First, loosen the locking screw on the eccentric sleeve of the bearing with an Allen wrench, and then insert the counterbore on the eccentric sleeve of the top cover with a small iron bar, and loosen the eccentric sleeve against the rotation direction of the shaft.
2. Loosen the bolt fixing the bearing seat. Remove the bearing along with the bearing housing from the shaft. Note before removing the bearing housing at one end of the shaft. The bearing seat bolt on the other end of the shaft shall be loosened to avoid damage caused by mutual locking of the two ends of the bearing.
