💡 What is a steel spacer bushing used for in precision machinery?

In short, it's a hardened wear-resistant sleeve that sits between moving parts to maintain precise spacing and alignment under load.

- Used to maintain shaft-to-housing clearance in rotating assemblies
- Reduces wear by providing a hard, smooth surface between parts
- Fits standard metric tolerances and can be trimmed or replaced as needed
