Roller bearings  and automatically compensate the relative deviation of the center line of bearing to the bearing capacity of the normal working state of tune is called Rolling Mind. As the bearing bore and shaft machining and installation errors, and loaded songs deformation around the rear axle, shaft and inner and outer axis can not maintain the overlap in their work, would produce a certain deflection.

Bearing ring cracks in the four reasons:Engine oil is rather more than less errors do not surface Rockwell hardness scale, there are three to choose from. No matter how all the possible types of grease, oil check and fill methods, pollution refers to the dust, linear bearings do not rotate load to bear, resulting in greater power loss. Their contact area is always to produce elastic deformation, while also allowed to combine the universal groups matching bearings,

 Entity type needle roller bearings: a basic structure of the inner bearing NU type cylindrical roller bearings the same, but with needle, size can be reduced, and can withstand large radial load bearing without inner ring should have the right precision and hardness the axis of the mounting surface to use as a raceway. Main application of the cage: steel stamping cage Main use: car engines, transmissions, pumps, crawler excavators wheel,
 

Bearing type and feature E-type cylindrical roller bearings Main dimensions and bearing the same general import, but the roller diameter, length, number of increased load bearing capacity to increase correspondingly.With symbol "E" number on the basic NTN bearings in order to differentiate. Compared with the large load capacity, its design is very light. Because the bearing diameter and bearing the standard import different,

2, deep groove ball bearing type Post code C2 is smaller than normal internal radial clearance clearance C3 internal clearance greater than normal radial clearance C4 greater than C3 radial internal clearance C4 C5 is greater than the internal radial clearance DB layout back to back matches in the installation of two single deep groove ball bearings. DF matching layout in the face to install two separate deep groove ball bearings.

1: fag bearing installation:1, cleaning bearings and related partsHas been greased on both sides with bearings and oil seals or dust cover, seal bearings before installation without washing.2, InstallationBearing installation should be based on bearing structure, size and bearing components with the nature of the pressure should be directly added to the tight end with the ring surface was not passed through the rolling pressure,
 

1: Thrust ball bearings features:1, one-way thrust ball bearings can only support axial load in one direction from the axis of its ring structure, with a full set of ball seat and maintain the frame. Which axis ring installed in the shaft seat ring bore hole bigger than the shaft, seat hole can not be grinding.2, two-way thrust ball bearings can withstand import axial load in both directions on both sides it has a ring with the axial channel and the two seat,
 

1: bearing steel ball production process:1, grinding: the ball into the rough match with the rough size, upper and lower multi-channel measurements with the same concentric ring section slot grinding mill for the triangle, add oil, crude abrasives; on the disc rotation, the next disc Fixed. Ball machine, said more than rough mill. Necessary, coarse grinding can have Road.2, system of embryos: use of a variety of processes to produce a variety of spherical rough way.
