Bearing mass production of mechanical parts and manufacturing precision is very strict, and the high degree of technical specialization, therefore bearing varieties most readily available, should be more cost-effective to buy than repair, in addition to the economic, skf bearings repair, as well as its technical, which requires the the repairer fully understand the technical requirements of the one-way thrust ball bearings, bearings and parts thereof, in the structure, process and material characteristics, it would be difficult to guarantee the bearing repair desirable effect.
The benchmark unchanged combination repair method. Repair and adjust the size of the chain accuracy principle benchmark coincidence, use only a datum for the design basis, and all other role of surface repair this surface as the benchmark. This combination repair benchmarks easy to check the accuracy and reduce the accumulated error. For example, variable speed hydraulic coupling repair, often fag bearings body as benchmarks.
Benchmark to transform combinations repair. Sometimes deformation of the design basis is too big, can not be used, it is necessary to choose some other surface benchmark size chain re-integration. For example, if bearing the deformation is too large, it should be based on the rotary component basis, re-processing correction the nsk bearings body, and then re-processed out of the way thrust ball bearings body size, adjust the assembly dimension chain, using repair adjustment ring method, the detection and repair of chain order by size, and last up to control the accuracy of the closed ring.
The bearing seal device other role is to prevent grease leakage from the the timken bearings parts in. If the oil spill, will soon destroy the normal lubrication of the bearing, the bearing and burn because of fever. Another poor sealing device not only oil spills caused by extravagance, but also pollute the mechanical equipment and processing products. Therefore, to make the machine run, one-way thrust ball bearings must have good sealing device.
1, the first View ian bearings outer packaging is clear, under normal circumstances, a one-way thrust ball bearings are factory brand has its own dedicated external packaging designers to design and arrange the factory production production production conditions clearance, therefore bearing packaging both from the line to the blocks of color are very clear.
2, bearing the stamp of the word is clear, in the the bearing body will lure brand words, labels, etc..
Bearing body, bearing a hybrid ring, left hand holding the sleeve bearing the body of the one-way thrust ball bearings rotation right hand fluctuations jacket so that it, to hear whether there are hybrid ring.
Bearing chamfer is uniform so-called bearing chamfer, which is the junction of the horizontal surface with a written bearing counterfeit due to the limitations of the production technology, the in these poo angle angle parts handling unsatisfactory.
5, the bearing surface of the muddy traces of oil.
The above points is to determine the bearing in purchase should pay special attention to.
