Grease selection is generally under INA bearing speed, temperature conditions, noise requirements and other aspects of starting torque selection, requiring a variety of oils and fats business staff performance very understanding. Inside the bearing lubrication to reduce friction and wear, to prevent burning stick. Grease lubrication is aimed at INA bearing rings, rolling elements and to maintain contact with each other part, to prevent contact, reducing friction and wear. But also to prevent dust and debris inside the bearing, or to prevent rust, corrosion effect. Therefore, the choice of fat is very important, we should choose high-quality, appropriate model. Bearing lubrication methods, divided into grease and oil lubrication. In order to make a good play function INA bearings, first, to select the appropriate conditions of use, purpose of use lubrication method. Consider only lubrication, oil lubrication dominant. However, there can be simplified grease around the bearing structure of expertise, the grease and oil lubrication compare the pros and cons.
INA bearing lubrication can be divided into oil lubrication and grease lubrication. Oil lubricated bearings are generally used form of bearings, grease lubricated bearings generally use shields or rubber seals seal. Dust cover for high temperature or environment good parts, seals of contact seals and non-contact sealing, the contact seal dustproof performance is good but the starting torque, non-fit seal starting torque is small, but the sealing performance no contact is good. Therefore, the choice should be noted that, to select a suitable method seal.
