Smooth bearing grease filling quantity more and less important role!

Bearing is in an important fittings, machinery and equipment in order to make the bearing can be normal operation, reduce the bearing wear, extend bearing life, everyone know must smooth filling grease, so smooth bearing grease filling quantity more and less important role. But an unlimited use smooth grease to the bearing can stop smooth right? What time should the change fat and should be in a few fat? These are bearing maintenance technology of complex problems. Smooth grease for bearings have very good effect, its adhesion, abrasion resistance, temperature tolerance, rust and smoothness are good, can improve the high temperature oxidation resistance, delay aging, can dissolve carbon deposition, avoid poly metal abrasive dust and oil pollution, the progress in mechanical, compression of abrasion resistance and corrosion resistance. But the more smooth grease filling amount, the greater the friction torque. The same filling amount, the sealed bearing friction torque is greater than the open bearing. Smooth the grease filling amounts to 60% of bearing internal space volume, friction torque no longer increases obviously. This is due to open in the bearing is smooth fat big local has been extrusion, and smooth of the sealed bearing grease also once because of leakage. With the increase of smooth grease filling amount, bearing temperature rise of linear progress, the same filling amount, sealed bearing temperature rise is higher than the open bearings. Common thought, sealed smooth of the rolling bearing grease filling amount, shall not go beyond the internal space of about 50% at most. By definition, smooth add it or not there is a solution of bearing, equipment supplier in the equipment before delivery once set related to the smooth solution, after repeatedly finishing that various debugging experiment. But, when the staff practice of operation, short-term change in smooth oil is very common things, and often add fat more smooth.
