💡 Why use a separate inner ring in needle roller assemblies?
When a shaft cannot serve as a raceway, inner rings provide:
- A hardened, precision surface for longer bearing life
- Better load distribution and improved wear resistance
- Flexibility to use standard needle rollers even on softer shafts
A solid choice for rebuilding or upgrading needle bearing setups. Let me know if you want the matching rollers or outer race!
