Bearing radial clearance, some unqualified can be adjusted after installation, such as the angular contact ball bearings, tapered roller bearings;
Some are in manufacturing has been adjusted according to the prescribed standards and unqualified can no longer after installation and adjustment, such as deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearing, spherical roller bearing, etc.
Bearing and shaft when installation, must check the perpendicularity of the shaft neck shoulder and shoulder root radius conform to the requirements before use;
For welding of bearing retainer applicability is wide and can, in principle, the forging can use flash butt welding of metal materials.
Shell between aperture and bearing outside diameter surface directly produce the trace of the slide hammer percussion bearing inner ring installation (
Or outer ring)
Interference fit of the bearing and banned direct percussion hammer bearing inner ring (
Or outer ring)
End face, it's so easy to guard the bad.
First look at the samples' repair bearing principle schematic picture, in the process to avoid porosity;
Coated sauvy SD material H, after heat curing after forming.
If power larger pole motor, the bearing model number is larger, light series column bearing also up to the limit speed of hard, also can change the bearing grease to thin oil.
Make initial lubrication of the friction surface, can start, after the check, the number of ring bar into the factory inspection found no raw material defect, which can determine the hole is formed in the process of forging.

Tolerance grade meet the requirements of standard ISO levels of tapered roller bearings.
GCr abrasion resistance and hardenability higher than GCr steel, bearing steel cutting machining, cold strain and plastic medium, poor weldability, is more sensitive on white dots to form, heat treatment has a tendency to temper brittleness.
Is used mainly for internal combustion engine, electric locomotives, automobiles, tractors, machine tools, rolling mill, boring machine, mining machinery, general machinery, mechanical transmission and high-speed rotating a high load bearing of steel ball, roller and ring.
Repair process is simple: use the sauvy tooling repair process to ensure the repair concentricity, then using carbon nano polymer materials SD with repair tooling complete bearing wear size of recovery, to that of the mating surface of bearing inner ring to %.
