Reliable coupling

We use these for high-torque applications. The elastic element absorbs shock well. Highly recommend for industrial machinery.

Heavy duty steel. Make sure to check your bore size before ordering. Good value for the price compared to local suppliers.

Perfect fit for our pump

Installed this on a hydraulic pump setup. The keyway alignment was precise and the steel feels robust. No vibration issues so far.

Good quality industrial part

Solid construction. Took a day extra to arrive but the product matches the description perfectly. Works well with our motor shaft.
