Single-piece IRB1412 inner ring for shell bearings, 7/8 in ID
✔️ 7/8 in ID (22.23 mm), 1-1/8 in OD (28.58 mm), 19.43 mm wide

The IRB1412 inner ring is the core component that forms the inner race in a shell-type needle roller bearing system. It’s designed to work with outer races and needle rollers in compact machinery, providing precise bore alignment and reliable load distribution in automation, conveyors, and other space-limited equipment.

✅ Bore type: Tapered
✅ Material: High carbon steel
✅ Shell-type compatibility: BA1812Z, BHA1812Z, YB1812
✅ Origin: Japan (single-piece inner ring)

💡 What is the purpose of an inner ring in shell-type bearing assemblies? Here's a handy explanation to help you decide if this part fits your setup. - It acts as the inner race to support radial loads and maintain spacing with outer components. - It works with BA1812Z/BHA1812Z and YB1812 to form a compact shell-type unit. - It makes maintenance easier by allowing inner-ring replacement without rebuilding the whole bearing. - It helps maintain alignment in space-constrained machines like conveyors and robotics.
