Perfect fit for our pumps

We replaced the worn-out pads on our industrial water pumps with these Korean-made units. The fit is precise, and the vibration levels dropped significantly immediately after installation.

Excellent shock absorption

These buffer pads handle the torque spikes from our conveyor system much better than the generic rubber ones we used previously. Highly recommended for heavy-duty use.

Reduced noise significantly

Our machinery was making a loud clattering noise due to worn couplings. After installing these elastic pads, the operation is whisper-quiet. Very satisfied.

Good quality material

The polyurethane feels very durable and resilient. It has been running for three weeks now without any signs of cracking or deformation under load.

Fast shipping and great product

Arrived quickly and exactly as described. The hex shape matches our JAC coupling perfectly. No issues with alignment during setup.

Solid replacement part

Works well as a direct replacement. The only reason for 4 stars instead of 5 is that the color was slightly lighter than expected, but performance is unaffected.

5 FAQ

Q: Does this come in different hardness levels?

A: This specific listing is for the 92A Shore hardness version, which offers a balance of flexibility and torque transmission. Other hardness levels may be available upon request.

Q: How often should these buffer pads be replaced?

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

Q: Is this compatible with standard JAC 42 couplings?

A: Yes, this star spider buffer is designed to fit standard JAC type jaw couplings, including size 42, provided the jaw dimensions match the standard specifications.

Q: What is the maximum operating temperature for this pad?

A: The polyurethane material is rated for continuous operation between -30°C and +80°C. Exposure to temperatures outside this range may affect elasticity and lifespan.

Q: Is this product oil resistant?

A: Yes, the high-grade polyurethane used in these pads offers good resistance to oils and greases commonly found in industrial environments, though prolonged exposure to harsh chemicals should be avoided.
