Solid construction, heavy duty
Very robust coupling. It is quite heavy due to the cast iron material, which gives me confidence in its durability. Deducted one star only because shipping took longer than expected.

Reliable replacement part
Bought this to replace a worn-out unit on a legacy system. It bolted right up and has been running smoothly for three months now. The elastomer shows no signs of wear yet.

Good value for money
For the price, this is a high-quality coupling. The finish is good, and there are no casting defects. Just make sure you measure your shafts carefully before ordering the size.

Perfect fit for our industrial pump
We ordered the 130mm version for a large water pump setup. The cast iron quality is excellent, and the hexagonal elastomer fits snugly without any play. Installation was straightforward.

Exactly as described
The dimensions matched our specifications perfectly. The back-to-back wheel design made alignment much easier than with our previous couplings. Highly recommended for maintenance teams.

Great vibration damping
The plum elastomer does a fantastic job of absorbing vibrations between the motor and the pump. Noise levels in our facility have decreased noticeably since installation.
Q: Do you offer bulk pricing for orders over 50 units?
A: Yes, we offer discounted pricing for bulk orders. Please contact our sales team directly through the 'Contact Seller' button with your required quantity for a custom quote.
Q: Does this coupling come with the elastomer spider included?
A: Yes, the package includes the cast iron jaws and the hexagonal plum elastomer spider pre-installed or packaged together.
Q: Can I use the 120mm version if my current setup is 125mm?
A: No, these couplings require an exact match for the outer diameter and bore sizes to ensure safe torque transmission and proper alignment. Please select the correct size for your machinery.
Q: What is the maximum operating temperature for the elastomer?
A: The standard elastomer is rated for continuous operation between -30°C and +80°C. For higher temperatures, please contact us for alternative material options.
Q: Is this suitable for high-speed applications?
A: This three-jaw design is generally suitable for moderate speeds typical of water pump applications. For very high RPM applications, please consult the technical datasheet for balance ratings.
