NSK Two-way thrust ball bearings how to properly care
Today, our bearing engineers want to introduce the contents of the two-way thrust ball NSK bearings how to properly maintain, the following is the specific content.
NSK bearings Thrust ball bearings during maintenance , excessive grease really have a lot harm. Since grease has good adhesion , abrasion resistance, temperature resistance , corrosion resistance and lubricity , high temperature oxidation resistance can progress , slow aging, can be dissolved carbon, metal wear debris and oil to prevent the knot together , progressive mechanical abrasion, pressure and corrosion resistance .
If the amount of grease fills the more the greater the friction torque . The same filling amount , sealed bearing friction torque is greater than the open bearings . Commensurate with the amount of grease filling skf bearing 60% of the volume of the internal space after the friction torque is no longer significant increases. This is because the open- bearing grease large departments have been extruded and sealed bearing grease leakage has also been the reason . Followed by an increase in the amount of grease filled , two-way thrust ball bearing temperature linear progress , the same filler content , skf bearing temperature rise was higher than the open bearings . Generally believed , sealed bearing grease fill quantity to move , to a maximum of about 50% of the internal space . The tests showed that two-way thrust ball bearings for 20-30% most affordable.
