SKF bidirectional thrust ball bearing should pay attention to when using smooth fat

Smooth fat is bidirectional thrust ball bearing in the work not to short, any smooth is inseparable from the care for the maintenance of SKF bearing grease, someone asked, more smooth and fat? Of course, the answer can not, just below the bidirectional thrust ball bearing in the use of smooth fat should pay attention to matters. Bidirectional thrust ball bearing in the remaining, smooth excessive fat actually have a lot of harm. Because the smooth grease has good adhesion, abrasion resistance, temperature tolerance, rust and smoothness, and 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. If the more smooth grease filling amount, the greater the friction torque will be. The same filling amount, the sealed bearing friction torque is greater than the open bearing. Smooth grease filling amounts to 60% of the SKF 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, two-way thrust ball bearings temperature linear progress, the same filling amount, SKF 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. Shawki and Mokhtar experiments indicate that the bidirectional thrust ball bearing, 20% to 30% in the most suitable.
