Exact Fit

Ordered the ROTEX 28 for a servo motor application. The bore tolerance is precise, and the keyway alignment is spot on. No modifications needed during installation.

Genuine KTR Quality

Received the ROTEX 42 coupling exactly as described. The casting quality is superb, and you can immediately tell this is an original German import. Fits perfectly on our motor shaft.

Superior Durability

We have been using KTR couplings in our factory for years. This purchase for a new line of machinery maintains that standard. The cast iron finish is robust and ready for harsh environments.

Great product, shipping took time

The coupling itself is flawless. I ordered the Aluminum version for a lighter application. Only giving 4 stars because international shipping took a bit longer than expected, but the product quality makes up for it.

Perfect for Industrial Pumps

We replaced a worn-out coupling on our main water pump with the Cast Iron version. Installation was straightforward, and the vibration dampening is excellent. Highly recommended for heavy-duty use.

Reliable Replacement Part

Needed a specific size (ROTEX 55) for a conveyor system. This matched the OEM specifications perfectly. The spider element included was the correct hardness for our torque requirements.

5 FAQ

Q: What is the lead time for bulk orders of size 90 and 100?

A: Standard sizes usually ship within 2-3 business days. For bulk orders of larger sizes like 90 and 100, please allow 5-7 business days for processing and shipment preparation.

Q: Are these genuine KTR Germany products or replicas?

A: These are 100% genuine KTR products imported directly from Germany. Each unit comes with original packaging and manufacturer markings to verify authenticity.

Q: What is the difference between the Cast Iron and Cast Aluminum versions?

A: Cast Iron (GG25) offers higher strength and is suitable for high-torque and heavy-load applications. Cast Aluminum (AlCuMgPb) is significantly lighter and ideal for applications where weight reduction and lower inertia are critical, though with slightly lower maximum torque ratings.

Q: Does this coupling come with the elastic spider element included?

A: Yes, all ROTEX GS couplings listed here include the appropriate polyurethane spider element pre-installed or packaged together based on the selected size.

Q: Can I get a custom bore size for the ROTEX 65?

A: While we stock standard bore sizes, custom machining services are available upon request. Please contact our sales team with your specific shaft diameter requirements for a quote.
