Weld on hub adapter for sprocket drives (Unit)
✔️ 1-1/8 inch bore fits shafts and 1-5/8 inch OD holes for gear setup

This single aftermarket piece connects your drive shaft to compatible W series components, swapping out old part numbers WSH20018 and RBW1-18. It mounts via simple arc welding and takes massive rotational pull without twisting. Mechanics install these straight onto aged frames, grain elevators, and factory conveyors to restore smooth power flow.

✅ Machined 1-1/8 inch keyed bore accepts standard drive shafts
✅ 1-5/8 inch outer diameter hole matches W series sprocket bores
✅ Direct fit drop in solution replaces WSH20018 and RBW1-18 part numbers
✅ Rugged steel body designed for steady welding and heavy load cycles

💡 What makes a welded hub adapter handy compared to standard friction locks?
A proper weld actually seats the rotating mass dead firm way tighter than sloppy slip collars ever could.
- Weld seams spread heavy stress across the full metal face instead of digging into shaft grooves
- Precise inner sizing keeps tensioners aligned while pulling hard on farm gear or factory lines
- Drop these replacements straight onto existing axles to skip tedious drilling jigs entirely
