1, the choice of Bearing: Bearing in general be selected by the user and technical personnel in accordance with the conditions of use of complementary products and to withstand the load on the bearings. Business people to understand whether the user's actual load bearing consistent with the selected bearings reach the requirements, as soon as possible to advise clients to re-election model, but unless special products in the choice of models generally do not have any problems.
2.Bearing INA clearance choice: buy bearings usually only informed in what type, grade, rarely will the clearance request, the business must ask clear bearing conditions of use, which combination of the speed of the bearing. temperature, with the tolerances are directly related to the choice of the bearing clearance. Generally at 3500 rev / min below the speed of the motor mostly CM clearance, such as high temperature and high-speed motor requires a relatively large clearance. Bearing clearance in the assembly because the narrowing of the hole up and cylindrical lead to a reduction in clearance to reduce the amount of interference amount × 60% = (bearing chamber except aluminum). Such as bearing assembly clearance is 0.01mm, and the amount of interference in the assembly of 0.01mm, the clearance after the bearing assembly is 0.004mm. Theoretically bearing zero clearance, noise and life to achieve the best state, but in actual operation taking into account the temperature rise and other issues bearing clearance after assembly 0.002mm-0.004mm better.
3.The choice of grease: grease the choice is generally based on the combination of bearing speed, temperature conditions, noise requirements and starting torque to choose the business people know much about the performance of the various oils.
4, bearing the seal type choices: INA Bearing lubrication can be divided into the oil lubrication and grease. Oil lubricated bearings generally is the choice of bearings, grease lubricated bearings generally used in the dust cover or rubber seal Sealing. Applicable to the good parts of high or use dust cover, seal the sub-contact seal and non-contact seal two contact seal dustproof performance is good but the starting torque, non-sealed starter torque is small, but the sealing performance no-contact.
