Excellent durability

We have been using these 10H elements for six months now in a high-torque application. No signs of wear or cracking yet. Highly recommended for heavy machinery.

Perfect fit for our conveyor system

Ordered the 9H size for a replacement on our main conveyor line. The fit was precise, and the rubber quality feels very durable. Installation took less than 20 minutes.

Exact replacement part

Hard to find specific sizes like 7H locally. These matched the original equipment manufacturer specs perfectly. Great solution for keeping our old machines running.

Reliable supplier

Bought a mixed batch of 8H and 11H for different units. All pieces were uniform in quality and dimension. Will definitely order again when maintenance is due.

Good value, fast shipping

These couplings work well for our pump motors. They reduced the vibration noticeably. Only giving 4 stars because the packaging was a bit crushed, though the product inside was fine.

Solid performance

The elasticity is just right for absorbing shocks during startup. The material seems resistant to oil exposure which is crucial for our workshop environment.

5 FAQ

Q: Do you offer these in a red color for safety coding?

A: Currently, we only stock these in standard black NBR rubber. Custom colors are not available for individual orders at this time.

Q: Can these withstand exposure to hydraulic fluid?

A: Yes, the Nitrile Rubber (NBR) material used offers good resistance to oils, greases, and hydraulic fluids, making them suitable for most industrial hydraulic environments.

Q: Are these compatible with Lovejoy H-series couplings?

A: Yes, our 6H through 11H elastic elements are designed to be fully compatible with standard H-series gear coupling hubs found in most industrial applications.

Q: What is the maximum torque rating for the 10H size?

A: The 10H element typically supports nominal torque up to 1,450 Nm, but please consult your specific machinery manual as ratings can vary based on hub condition and alignment.

Q: How often should these be replaced under continuous operation?

A: Replacement intervals depend on load and environment. We recommend inspecting them every 6 months and replacing if cracks, excessive wear, or deformation are visible.
