A lubrication hole is a prepared bore in a machine part through which lubricants can be specifically supplied to the friction points. It enables continuous lubrication, reduces wear, and increases the service life of the components.
Lubrication holes serve to:
- Reduce friction between moving parts
- Decrease wear and overheating
- Provide targeted lubrication of hard-to-reach areas
- Ensure service life and functional reliability
Design and application
- Can be through-holes or blind holes, depending on the lubricant and installation space
- Are often used in conjunction with lubrication channels or bores in the spindle
- In ball screws, they guide lubricant directly to the balls to ensure smooth circulation.
