High durability

We use these in high-vibration environments. This elastomer has lasted significantly longer than generic alternatives. The color coding makes identification easy during maintenance.

Standard replacement part

Exactly what is needed for routine maintenance on our conveyor systems. The hardness seems consistent with previous batches we have purchased.

Good product, fast shipping

The part is authentic and works well. Only giving 4 stars because the packaging was slightly damaged upon arrival, though the item itself was fine.

Perfect fit for our machinery

Ordered this specific orange-yellow element for a GR19 coupling. The dimensions were exact, and it installed without any issues. Genuine KTR quality as expected.

Solved our alignment vibration

Replaced the worn-out white element with this orange-yellow one. The reduction in vibration was immediate. Highly recommended for precision applications.

5 FAQ

Q: What does the orange-yellow color indicate regarding hardness?

A: The orange-yellow color typically indicates a Shore A hardness of approximately 92, offering a balance between flexibility and torque transmission.

Q: Can this be used in outdoor applications exposed to sunlight?

A: Yes, the polyurethane material has good resistance to UV radiation, but prolonged direct exposure may reduce lifespan over several years.

Q: What is the maximum operating temperature for this specific color code?

A: For the orange-yellow element, the standard continuous operating temperature range is from -30°C to +90°C.

Q: Is this element compatible with non-KTR brand couplings?

A: While dimensions follow industry standards for GR19, we recommend using it with genuine KTR hubs to ensure optimal performance and warranty coverage.

Q: Does this package include the metal hubs?

A: No, this listing is for the elastomer spider element only. The metal hubs must be purchased separately if needed.
