How to choose the right lubricating oils or greases for bearings?

Lubricating oils and greases are the most common lubricants in the use of bearings. When we maintain bearings, lubrication is of great help to the operation of bearings, such as reducing the coefficient of friction. So what do we need to know when choosing bearing lubricants and greases for lubrication? First of all, w ... + Read more

What are the common materials for bearings?

Bearing steel is used to make balls, rollers and bearing rings. Bearings are subjected to extreme pressure and friction during operation, so bearing steels are required to have high and uniform hardness and wear resistance, as well as high elastic limits. The requirements for the uniformity of the chemical composition ... + Read more

What is the advantage of crossed roller bearing for industrial robots?

Crossed roller bearing is a special type bearing with inner ring split and outer ring rotating. Since the split inner ring or outer ring is installed in the roller and the spacer, it is fixed with the cross roller collar to prevent separation from each other, so the operation is simple when installing the cross roller ... + Read more
