Perfect fit for my lathe motor

The bore size was exact and the keyway aligned perfectly. The steel feels solid and the spider element fits snugly without too much force. Highly recommend for industrial machinery.

Handles high torque well

Using this on a pump motor setup. It handles the load without vibration. The elastic spider absorbs shock nicely. Delivery was faster than expected.

Exact specs as described

We ordered multiple units for our assembly line. Dimensions match the technical drawings provided. The black oxide coating provides good corrosion resistance.

Value buy

Good value for money. The set screws included were adequate. Just make sure to check your shaft diameter before ordering as the range is wide.

Good quality, slight machining marks

Overall a great coupling for the price. There were some minor machining marks on the hub surface, but nothing that affects performance. Torque transmission is smooth.
