IKO bearings with the role that still makes Rolling circle and rotations were still part of the installation position (usually the bearing) and the rotating part (usually the shaft) consolidation together in order to achieve a pass in a rotating state load and limited The basic tasks of the movement system relative to the stationary location.
    
Shaft and bearing, roller bearing requirements in three directions, radial, axial and tangential direction is fixed in its position. Radial and tangential positioning by IKO bearing ring tight fit recoverable axial position only in rare cases, a tight fit; commonly used parts of the axial limit, such as end cap and retaining ring, the axial position limited within the scope of the clearance.
    
Select tie should focus on the following four points:
    
(1) bearing ring circumference surface should be well supported and uniform force, in order to reduce deformation, and can give full play to the carrying capacity of the IKO bearings.
    
(2) in its mating surface of the ferrule is not along the tangent direction of sliding, otherwise it will damage the mating surface.
    
(3) The free end bearing with the shaft and the bearing hole, the length of the change must be able to adapt, which must adapt to the swimming ability of the axial position within a certain range.
    
(4) must pay attention to IKO bearing installation and removal is simple, saving time and labor expenditure.
    
Allows the speed of the rolling bearing type, size, precision, maintaining factors determine the frame type, load, lubrication, and cooling methods. Bearing table lists the standard precision bearings under oil lubrication and grease lubrication allows the speed.
 
Typically, deep groove ball bearings, auto-aligning ball bearings and cylindrical roller bearings are suitable for high-speed operation of the occasion.
    
The bearings of the dimensional accuracy and rotation accuracy is in accordance with ISO and JIS standards. For the mechanical requirements of high precision and high-speed operation, it is recommended to use five or more precision bearings, deep groove ball bearings, angular contact ball bearings or cylindrical roller bearings for high-precision operation of mechanical Rigid, IKO bearings, rolling element and raceway contact surface pressure will produce elastic deformation. Some mechanical need to minimize the elastic deformation. Roller bearings ball bearings produced by elastic deformation.
    
In addition, in some cases rolling bearing to be applied preload to increase rigidity. This process typically used for deep groove ball bearings, angular contact ball bearing and tapered roller bearing inner ring offset, shaft bending, shaft or bearing housing tolerances change, with the error will cause the eccentricity of the inner and outer rings. In order to prevent the eccentric angle is too large, self-aligning ball bearings, aligning roller bearings, aligning bearing is the better choice. Voice frequency and torque, the rolling bearings are manufactured according to the production of high-precision standard, small voice and torque. Deep groove ball bearings and cylindrical roller bearings are suitable for low voice, low torque requirements of the occasion.
