Ball screw assemblies can be lubricated to improve wear resistance and transmission efficiency. Lubricants are divided into two major categories: lubricating oils and greases. For lubricating oils, machine oil, 90-180 grade turbine oil, or 140 grade spindle oil can be used. Lithium-based greases are suitable for lubricating. Grease is applied to the thread raceways and the housing space where the nut is installed, while lubricating oil is injected into the nut space through the oil hole on the housing.  Ball screw assemblies and other transmission components with rolling friction can be considered to work with almost no wear as long as abrasive particles and chemically active substances are prevented from entering. However, if dirt falls into the raceways or dirty lubricating oil is used, it will not only hinder the normal operation of the balls but also cause a sharp increase in wear.  Usually, sealing rings are installed at both ends of the nut. Since the sealing rings are in direct contact with the screw, the dust-proof effect is good, but it also increases the frictional resistance torque of the ball screw nut assembly. To avoid this frictional resistance torque, a non-contact labyrinth seal made of relatively hard plastic can be used. Its inner hole is made into a shape opposite to the thread raceway of the ball screw, with a certain gap left.   1.
