4.Analysis of the precautions for bearing matching

According to the journal's optional bearing, the bearing of the specified repair size is selected to meet the specified matching clearance. The method has good quality, easy operation and shortened working hours, but the following items should be noted when selecting bearings:
When selecting a new bearing, check the roundness and taper error of the bearing housing hole to meet the standard. When inspecting, tighten the bearing cap and the seat according to the specified torque. Check the cylinder or inner diameter micrometer. The roundness and taper error should not exceed 0.02mm. Otherwise, the normal fit clearance between the bearing and the journal will be damaged, and the bearing and journal will be accelerated. Wear and tear. After the new bearing is placed in the seat hole, the upper and lower bearing pieces
