SKF bearings are precision components, and its use shall carefully carried out. No matter how high-performance bearings, if used improperly, you will not get the expected performance. Note about the use of bearings, as follows:
1, to keep the bearings in and around clean:
Even the eyes can not see dust, also bearing a bad influence. Therefore, to keep the surroundings clean so that dust will not invade the bearing.
2, use caution:
To give the bearing a strong impact in use, will have a scar and indentation as the cause of the accident. Severe cases, it will crack, fracture, it is necessary to pay attention.
3, using the proper operation of tools:
Avoid to replace existing tools, you must use the right tools.
4, pay attention to the corrosion of the bearings:
Operation bearing the sweat of the hands become rusty. Pay attention to clean hands operation, it is best to try to wear gloves.
The only good maintenance of bearings, bearing life, longer. Now, to give you analysis of SKF bearings in the process of daily use, it should be noted that:
Bearing options:
Bearing generally 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 the user's actual load is not consistent with the selected bearing if the bearing to 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, the bearing clearance options:
Purchase bearings usually only informed in what type, grade, will have very little bearing clearance request, the business must ask clear bearing conditions of use, speed of the bearing temperature tolerances are directly related to bearing clearance choice.
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).
For example: the clearance in the bearing assembly is 0.01mm, and the amount of interference in the assembly of 0.01mm, the clearance after the bearing assembly is 0.004mm. In theoretically bearings in 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 bearing grease:
The choice of grease bearing speed, temperature, 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:
The lubrication of the bearing can be divided into the oil lubrication and grease. The oil lubricated bearings generally is an optional form of bearings, grease lubricated bearings generally used in the dust cover or rubber seals seal.
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.
SKF bearings, to understand more about the use of knowledge bearing, select the correct installation methods possible to extend the life of the bearings.
