Solid construction, heavy duty

Very robust coupling. It handles the vibration from our motor setup well thanks to the hex spider. Took off one star because shipping took a bit longer than anticipated, but the product itself is great.

Perfect fit for our industrial pumps

We ordered the 105mm size for a retrofit project. The cast iron quality is excellent, and the back-to-back design made alignment much easier than expected. The included gasket was a nice touch.

Easy installation

The machining on the hubs is precise. We had no issues mounting these on our shafts. The elastic spider provides good flexibility without sacrificing torque transmission.

Reliable performance

Been running these in our facility for three months now with zero failures. The back-to-back wheel design is sturdy. Just ensure you select the correct size as they are specific.

Great value for money

Compared to other suppliers, the price here is unbeatable for cast iron couplings of this caliber. The 90mm version fits our small conveyor motors perfectly. Highly recommend.

Excellent replacement part

Replaced an old worn-out coupling with this 120mm model. The difference in noise reduction is immediate due to the new elastic spider. Very satisfied with the purchase.
