Needle Roller Bearing Inner Ring for Inch Series Drawn Cup Bearings, Regular Width, One Inch Inner Diameter, One And A Quarter Inch Outer Diameter, One Inch Width, Hardened Ground Raceway, Loose Transition Fit

High-quality inner ring for inch series needle roller bearings in drawn cup setups.
✔️ 1-inch inner diameter, 1.25-inch outer, 1-inch width, hardened ground raceway, loose transition fit for easy shaft mounting

This inner ring acts as a hardened raceway for needle roller bearings, stepping in when the shaft isn't suitable for that role. It's commonly found in machinery like automotive transmissions, farm equipment, pumps, and engines where reliable motion is key.

✅ Inner diameter of 1 inch for precise shaft fitting
✅ Outer diameter of 1.25 inches to match drawn cup bearings
✅ Width of 1 inch for standard compatibility in tight spaces
✅ Hardened and ground steel construction for long-lasting durability
✅ Loose transition fit that simplifies installation on various shafts

💡 What does an inner ring do in needle roller bearing systems? This component ensures smooth operation by providing a dedicated raceway, reducing wear on the shaft. - Helps handle radial loads in high-speed applications - Boosts setup reliability for gear-driven machines - Prevents direct contact to extend equipment life - Works as a quick fix in mismatched shaft designs
