Good durability

Been running this for three months now under heavy load. No signs of cracking or wear yet. Slightly stiffer than the original OEM part but works well.

Bulk order success

Ordered twenty units for our workshop fleet. Consistent quality across all pieces. The decagonal shape aligns easily without forcing.

Perfect fit for my compressor

This replacement pad fits the GR90 coupling perfectly. The vibration on my air compressor has decreased significantly since installation. Great quality polyurethane.

Great value

Much cheaper than buying from the compressor manufacturer directly, and the performance is identical. Will buy again when needed.

Excellent shock absorption

My machine was making a clanking noise due to a worn-out spider. This new buffer pad silenced it immediately. Very happy with the purchase.

Works but tight fit

The material seems high quality, but it was a very tight fit getting it into the jaws. Had to use a bit of lubricant to slide it in. Once in, it works fine.

5 FAQ

Q: Is this compatible with Lovejoy L90 couplings?

A: While dimensions are similar, this pad is specifically molded for the GR90 standard. We recommend verifying your specific coupling model before purchasing to ensure a perfect fit.

Q: What is the expected lifespan under continuous operation?

A: Lifespan varies based on load and alignment, but under normal operating conditions, our polyurethane pads typically last between 12 to 18 months before replacement is recommended.

Q: Does the package include the metal hubs?

A: No, this listing is for the elastic buffer pad (spider wheel) only. The metal coupling hubs are not included.

Q: Can this withstand exposure to oil mist?

A: Yes, the high-grade polyurethane material used in this buffer pad offers good resistance to oil mist and common industrial lubricants found in compressor environments.

Q: How do I know if my current pad is worn out?

A: Signs of wear include visible cracks, chunks missing from the decagonal points, excessive vibration, or a knocking sound during startup and shutdown. If you see any deformation, replace it immediately.
