Excellent damping properties

The elastic rubber figure-8 design really shines in reducing noise and shock loads. Highly recommended for precision encoder applications.

Good value for industrial use

We replaced several old couplings with these. They handle minor misalignments well. The only reason for 4 stars is that the documentation could be more detailed regarding torque limits.

Durable and reliable

Been running these on our production line motors for three months now. No signs of wear on the rubber element, and vibration has decreased noticeably.

Great replacement part

Needed a specific GB standard coupling for a retrofit project. This unit worked flawlessly. The high toughness claim seems accurate based on our stress tests.

5 FAQ

Q: Is the rubber element replaceable if it wears out?

A: Yes, the flexible rubber figure-8 element is designed to be replaceable without needing to change the aluminum hubs.

Q: What is the lead time for bulk orders of over 100 units?

A: Bulk orders over 100 units usually ship within 5-7 business days. Please contact our sales team for a specific quote and timeline.

Q: Can this be used in an environment with occasional oil exposure?

A: The nitrile rubber used in the figure-8 element has good resistance to oils and greases, making it suitable for such environments.

Q: What is the maximum allowable parallel misalignment for this coupling?

A: For standard sizes, the maximum parallel misalignment is typically up to 0.5mm, but please refer to the specific size chart in the manual for exact tolerances.

Q: Does this come with the necessary clamping screws?

A: Yes, all necessary stainless steel clamping screws are included in the package.
