💡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
