Exact specification match

The dimensions matched the technical drawings for the N-EUPEX 180 exactly. No need for shimming or forcing the parts together.

Reliable for heavy duty use

We run these in a high-torque application on a conveyor system. They have held up perfectly for six months now with no signs of cracking or wear.

Great value

Bought a spare set for maintenance inventory. The material feels durable and the color coding makes it easy to identify the hardness type quickly.

Solved our alignment noise issue

Our motor was making a knocking sound due to old, hardened blocks. Replacing them with these restored smooth operation immediately. Highly recommended.

Perfect fit for our pumps

Ordered these to replace worn-out blocks on our Flender couplings. The fit was precise and installation took less than 20 minutes. Machine vibration is gone.

Good quality alternative

These work just as well as the OEM parts but at a fraction of the cost. Delivery was fast. Only giving 4 stars because the packaging was slightly damaged, though the product was fine.

5 FAQ

Q: Is there a warranty included with this product?

A: Yes, all our coupling components come with a 12-month manufacturer warranty against defects in material and workmanship under normal operating conditions.

Q: What is the Shore hardness of these yellow blocks?

A: The standard Yellow H-Type blocks typically have a Shore A hardness of approximately 92-95, designed for general industrial applications with moderate torque requirements.

Q: Are these blocks suitable for size 160 couplings as well?

A: Yes, this listing covers compatible elastic blocks for sizes 80 through 180. Please ensure you select the correct quantity for your specific coupling size during checkout.

Q: Do I need to lubricate the blocks before installation?

A: No, lubrication is not required and is generally not recommended for the elastic elements themselves. Ensure the metal hubs are clean and free of debris before inserting the blocks.

Q: Can these withstand outdoor weather conditions?

A: The polyurethane material offers good resistance to moisture and ozone, making them suitable for outdoor use. However, prolonged direct UV exposure may degrade the material over time, so shielding is advised if possible.
