Good adapter
Works as described. Shipping was fast and packaging protected the item well.
Description
This rigid coupling serves as an extended transmission adapter designed to connect motor shafts of differing diameters in high-torque applications. Constructed from stainless steel, the set-screw type mechanism ensures a secure and stable connection for power transmission. The extended design provides additional spacing between connected components while maintaining alignment under heavy load conditions. Ensure set screws are properly tightened against flat spots on the shafts to prevent slippage during operation.

Sturdy but tight
Very solid construction. Needed a bit of force to fit the shaft initially but settled well.
