💡Why are inner rings used with needle bearings?
Inner rings help create a perfect raceway when the shaft isn’t ready to roll:
-
Offers a hardened surface for needle rollers to glide on
-
Prevents shaft wear in high-load or high-speed setups
-
Helps when shaft tolerance is too loose or soft
-
Makes replacement and maintenance easier
