Reliable replacement part

Bought the size 28 for a conveyor motor. Fits perfectly into the GS coupling housing. The rubber feels robust and flexible. Highly recommend sticking to the original brand for safety and longevity.

Essential for maintenance

Keep a stock of these in various sizes for our factory floor. The durability is outstanding, and having the original rubber compound ensures the coupling performs as designed without premature wear on the hubs.

Perfect fit for our CNC machine

Ordered the size 42 buffer for a retrofit on our lathe. The quality is exactly what you expect from genuine KTR parts. Installation was straightforward and vibration has been significantly reduced.

Great product, slow shipping

The coupling pad itself is excellent and matches the specifications perfectly. Only giving 4 stars because international shipping took a bit longer than expected, but the product quality makes up for it.

Solved our alignment noise issue

Our pump system was making a knocking sound due to worn buffers. Replaced them with these KTR originals and the noise is completely gone. Very satisfied with the performance.

Genuine German quality

We tried a cheaper alternative before, but it wore out in two weeks. These original pads have been running smoothly for six months now under heavy load. Worth every penny.

5 FAQ

Q: What is the typical lifespan of these rubber pads?

A: Lifespan varies based on operating conditions such as torque loads, misalignment, and temperature. Under normal operating conditions, genuine KTR buffers typically last several years, but regular inspection is recommended.

Q: Can I mix different colors of buffers in the same coupling?

A: No, you should always use a complete set of buffers of the same size and hardness (color). Mixing different types can lead to uneven load distribution and premature failure of the coupling.

Q: Do you offer bulk discounts for factory orders?

A: Yes, we offer tiered pricing for bulk purchases. Please contact our sales team directly with the quantities and sizes you require, and we will provide a customized quote.

Q: How do I determine which size buffer I need for my coupling?

A: The size number (e.g., 19, 24, 38) corresponds directly to the size of your ROTEX GS coupling hub. Please check the marking on the metal hub or refer to your machine's manual to select the matching buffer size.

Q: Are these buffers resistant to oil and grease?

A: Yes, the standard KTR ROTEX elastic pads are made from a rubber compound that offers good resistance to hydraulic oils, mineral oils, and grease commonly found in industrial environments.
