Lubrication of precision DFU ball screw
- When using a ball screw, it must be lubricated adequately. Insufficient lubrication will increase the wear, cause failures or shorten the lifespan.
- When lubricating the DFU ball screw with grease, use a lithium soap-based grease with a dynamic viscosity of 30~140mm²/s (40°C). When lubricating with oil, use lubricants registered as ISO VG32~100.
- Generally, when thermal displacement of the screw shaft is important in high-speed applications or when used in low-temperature environments, it is recommended to use a lubricant with a lower base oil viscosity. Conversely, when used under conditions such as low speed, high temperature, vibration, and heavy loads, it is recommended to use a lubricant with a higher base oil viscosity.
