Bearing should not be adding too much grease

We know that the grease has good adhesion, abrasion resistance, temperature resistance, anti rust and lubrication, can improve the high temperature oxidation resistance, delay aging, can be dissolved carbon, prevent metal debris and oil binding, improving the corrosion resistance of mechanical wear resistance, pressure resistance and.

Understanding the movement process of lubricating greases in metric bearing, will naturally come to the conclusion: the grease for bearing too much. Grease much not only waste, but also harmful. The running speed of the bearing is higher, the greater the harm sex.

Grease filling in the friction torque, the larger. Filling quantity of the same, the friction torque of sealed bearing than open bearing. After grease filling amount equivalent to 60% of the volume of the inner space of the bearing friction torque, no longer increases significantly. This is due to open in the bearing grease most has been squeezed out, and sealing grease type bearings have leakage.

With the increasing amount of grease filled, linear increase the lift robotics bearing temperature, filling the same, but higher than the open bearing sealed bearing temperature rise.

Generally, grease sealed bearings filling amount, shall not exceed 50% of the internal space. Tests show that , ball bearing with 20% to 30% is the most suitable.‍
