Single Needle Roller Bearing Inner Ring For Stable Shaft Fit
✔️ Hardened steel raceway fits loose on shaft for industrial setups

This single replacement inner ring acts as a durable track surface when your primary shaft cannot handle direct roller contact. You install it directly alongside inch series drawn cup needle bearings for heavy load machinery. Shop mechanics rely on this handy upgrade to keep transmissions, pumps, and compressors rolling smooth during long shifts.

✅ Provides a secure sliding interface for your primary drive axle
✅ Features fully hardened and ground steel for long lasting wear life
✅ Pairs cleanly with standard Koyo Torrington inch series drawn cups
✅ Measures a precise 3/4 inch inner diameter and 1 inch outer diameter

💡 What allows a standalone needle roller inner ring to handle higher radial loads than a standard shaft?
Adding a dedicated raceway saves you the hassle of replacing entire axle housings when surface scoring happens on the job site.
- Hardened ground tracks maintain tight tolerances during heavy duty cycles
- Loose transitional mounting speeds up maintenance swaps on older gearboxes
- Needle style rollers distribute heavy radial forces evenly along the metal path
