Proper Installation:
Ensure concentricity between the screw, drive motor, and support bearings (avoid bending stress).
Ensure that the support bearings can withstand appropriate axial and radial loads (angular contact bearings are commonly used).
Avoid radial forces and bending moments on the screw.
The nut seat must be sufficiently rigid.
Adequate Lubrication:
This is critical to ensuring longevity and smooth operation.
Grease: Convenient, with long maintenance intervals, is suitable for most medium and low-speed applications. Requires regular replenishment or replacement.
Lubricating Oil: Provides good heat dissipation and is suitable for high speeds, high loads, or long strokes. A circulating lubrication system is required.
Select a dedicated ball screw lubricant.
Effective Dust Control:
Contaminants entering the raceway can significantly accelerate wear, leading to loss of precision and shortened life. Always use seals and consider additional protective covers for harsh environments.
Avoid Overloading:
The load should not exceed the rated dynamic or static load.
Monitor Temperature Rise:
Monitor temperature rise during high-speed or high-load operation. Overheating can shorten life or even damage the screw.
Regular inspections:
Check for noise, vibration, temperature rise, lubrication conditions, seal integrity, etc.
