Great value for money

Compared to other brands, this offers better material quality at a competitive price. The black oxide finish also provides good corrosion resistance in our workshop environment.

Perfect fit for our industrial pump

We replaced an old worn-out coupling with this XL star model. The 45 steel construction feels very robust, and the alignment was straightforward. It has been running smoothly for three weeks without any vibration issues.

Good quality, slightly heavy

The build quality is excellent and the torque capacity is exactly what we needed for our conveyor motor. It is a bit heavier than expected, but that speaks to the durability of the steel used.

Reliable for high load applications

Using this in a high-torque environment. So far, no signs of wear on the jaws or the elastic insert. Just make sure to torque the set screws correctly during installation.

Excellent vibration damping

The elastic spider element does a great job absorbing shocks. Our previous metal-to-metal coupling caused too much noise; this one runs quietly and efficiently.

Fast shipping and solid product

Ordered this for a urgent repair on a packaging machine. Arrived quickly and the dimensions matched our specs perfectly. Very satisfied with the purchase.

5 FAQ

Q: Does this coupling come with the elastic spider insert included?

A: Yes, the package includes the 45 steel hubs and the polyurethane elastic spider insert pre-installed or packed together.

Q: How do I know when the elastic spider needs replacement?

A: Inspect the spider periodically for cracks, deformation, or excessive wear. If you notice increased vibration or backlash in the system, it is time to replace the insert.

Q: Is the keyway standard DIN or ANSI?

A: Our standard manufacturing follows DIN 6885 for keyways, but we can accommodate ANSI standards upon request for bulk orders.

Q: What is the maximum bore size available for the XL series?

A: The XL series typically supports bore sizes up to 60mm, but please check the specific technical drawing in the product manual for exact tolerances.

Q: Can this be used in outdoor environments with rain exposure?

A: While the black oxide coating offers some protection, we recommend additional shielding or regular maintenance if used in direct, continuous rain to prevent long-term rusting.
