Great for encoder connections

Bought the 8mm to 10mm version. It fits perfectly on my stepper motor and encoder shaft. No backlash detected so far after two weeks of continuous running.

Reliable and sturdy

I've used these couplings in three different motor setups now. They are lightweight yet strong, and the aluminum alloy feels premium. Installation was straightforward.

Exceeded expectations

For the price, you cannot beat this coupling. It handles misalignment better than rigid couplers I've tried before. Will definitely order more sizes.

Solid choice for light industrial use

Very happy with the purchase. The only reason for 4 stars instead of 5 is that the set screws could be slightly longer, but standard replacements work fine.

Good value, minor machining marks

Works exactly as described. There were some very faint machining marks on the outer surface, but nothing that affects performance. The elasticity absorbs vibration well.

Perfect fit for my CNC project

The build quality is excellent. The clamping mechanism holds the shafts securely without any slip, even at high speeds. Highly recommended for precision applications.

5 FAQ

Q: Can this handle a shaft mismatch of 6mm to 14mm directly?

A: No, this specific unit is designed for one pair of bore sizes at a time (e.g., 6mm to 8mm). You need to select the specific combination you require when ordering.

Q: What is the maximum operating temperature for this aluminum alloy?

A: The aluminum alloy can generally withstand temperatures up to 150°C (302°F) without losing structural integrity, though we recommend staying below 100°C for optimal elastomer performance.

Q: Do you offer bulk discounts for orders over 50 units?

A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly through the 'Contact Seller' button for a custom quote.

Q: Is this suitable for high-torque servo motors?

A: This model is rated for 1.5 N·m. It is suitable for small to medium servo motors and encoders. For high-torque industrial servos, please check our heavy-duty series.

Q: Does this coupling come with set screws included?

A: Yes, each D32L40 coupling comes with the necessary set screws pre-installed or included in the package.
