💡 Why use a dedicated inner ring in needle roller bearing setups?
Inner rings provide a precision raceway when a shaft surface isn’t suitable for direct rolling contact.
- Reduces wear by offering a hardened, ground surface for the rollers
- Improves running accuracy in high-speed assemblies
- Helps maintain proper needle roller geometry under heavy loads
- Extends lifespan of both shaft and bearing in demanding applications

Grab this one when you need clean, stable rotation without modifying your shaft.
