Bearings are the basis of modern industrial parts
Bearings are basic components of modern industry, the operation of any industrial enterprises are inseparable from the work of bearing, bearing factory production equipment now has a very high status among any bearing production equipment are inseparable from the role, there is no bearing just like a person without a joint, can not make any exercise. Next we take a look at the bearing material bearing tolerances and heat treatment and other bearing clearance concept.
Including the bearing parts of the material used and ten of these materials to physical and chemical properties, the tower parts after quenching and tempering hardness, microstructure, carbide, crack, decarburization Cong soft spots, ring deformation, crushing balls trees, between the fire stability, fracture, grains and so on. Such as the use carburizing steel, as well as effective case hardened layer depth to be checked.
Including bearings tolerance level, dimensional tolerances and rotation accuracy: If the bearing inner and outer diameter and width deviation and changes in the amount of assembled bearing inner and outer diameter to jump power, the inner side facing the straightness of mercury inside the bar, the external appearance of song on the vertical face, assembled bearing inner and outer Ae bearing beating. Clearance group and N radial clearance and axial clearance and so on.
