Joint bearing allowable operating temperature is mainly determined by the pairing of the sliding surface between the bearing material, especially plastic material self-lubricating sliding surfaces bearing joints, its carrying capacity at high temperatures have decreased. When the sliding surface materials such as lubricating plain bearings pairing of steel / steel, four row cylindrical roller bearing the allowable operating temperature depends on the allowable operating temperature lubricant. But for all lubricated and self-lubricating bearing joints is concerned, may, within -30 ℃ ~ + 80 ℃ temperature range of use, and maintain the correct affordability.
Dip
Rolling bearing joints is much greater than the general inclination is adjustable heart, it is suitable for use in less demanding concentricity supporting parts, plain bearings form bearing structure with the inclination of the size, type, seal and bearing varies, Cylindrical roller bearing generally Spherical plain bearings tilt range is 3 ° ~ 15 °, inclination range of angular contact bearings are 2 ° ~ 3 °, inclination range of thrust bearings are 6 ° ~ 9 °.
Coordinate
In any case, Cylindrical roller bearing shall be chosen with the occurrence of uneven deformation of the ferrule, with the nature and level of their choice must be determined according to the bearing type, slim bearings and other support in the form of working conditions and loads. Handling
Plain Bearings
Joint bearing handling should follow the principle that the force exerted by the assembly and disassembly can not directly pass through the spherical sliding surface. Further, the auxiliary working tools should be used, such as a sleeve, disassembly, etc., Cylindrical roller bearing the loading force is applied directly to the outside, and uniformly applied to the mating ferrule, auxiliary heating or no-load handling methods.
Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.
