The main grease used for the push rod motor is the worm gear and the screw. The grease requirements for the two parts are different. Worm gears require grease to reduce noise, abrasion, extreme pressure and long life. Greases with slightly higher viscosity are generally recommended; screw rods require adhesion, anti-wear and extreme pressure, and long life. Generally, greases with lower viscosity and consistency of 1# are used.
