How to add oil-bearing grease

   In practice oil-bearing, if add too much grease, so the higher the speed, the greater the harm, at the same time, the more the greater the friction torque loadings. Under the same conditions of filling amount, the friction torque sealed bearings will be larger than the open bearings. When the filling amount of grease inside the bearing space volume equivalent to 60%, the friction torque is not significantly increased, which is due to open most of the bearing grease has been extruded, and grease sealed in the bearing Dropout has also been the reason. With the increase of the amount of grease filling, bearing temperature rise straight increase, the same quantity is filled, sealed bearing temperature rise was higher than open bearings. Generally believed, sealed rolling bearing grease filling amount, a maximum of about 50% of the internal space of the ball bearing to 20-30% is most appropriate.
   Grease with good adhesion, abrasion resistance, temperature resistance, rust resistance and lubricity, to improve the non-oil bearing high temperature oxidation resistance, anti-aging, can dissolve carbon deposits prevent metal wear debris and oil knot together, improve the mechanical abrasion, pressure and corrosion resistance. But by observing the motion of the bearing grease summary, we noted that: the bearing grease should not be excessive. Grease adds a not only a waste, but also counterproductive.
