Essential for preventative maintenance

Keep a few of these in stock. They are easy to swap out during scheduled downtime and prevent more serious damage to the spindle coupling jaws. Very satisfied.

Solid performance

Works as described. The hardness is just right for our application, providing enough flexibility without compromising torque transmission. Will buy again when needed.

Good quality material

The polyurethane feels very durable and resilient. Installation was straightforward. I gave it 4 stars only because shipping took a bit longer than expected, but the product itself is excellent.

Reduced noise significantly

Our spindle was making a humming noise due to a degraded coupling. This BM-80 pad solved the issue instantly. The octagonal shape aligns perfectly with our drive shaft.

Perfect fit for our BT40 machine

We replaced the worn-out pad on our vertical machining center with this octagonal buffer. The fit was precise, and the vibration levels dropped immediately. Highly recommended for maintenance teams.

Great replacement part

Exact match for the original equipment manufacturer part but at a better price point. The shock absorption capabilities are top-notch for high-speed operations.

5 FAQ

Q: Does the package include the metal jaws or just the plastic insert?

A: This package includes only the octagonal plum pad (the polyurethane insert). The metal coupling jaws are not included.

Q: Can this withstand exposure to coolant fluids?

A: Yes, the high-density polyurethane material is resistant to standard water-soluble and oil-based CNC coolants.

Q: What is the expected lifespan under continuous operation?

A: Lifespan varies based on load and speed, but under normal operating conditions, these pads typically last between 12 to 18 months before requiring replacement.

Q: Is this compatible with a BT50 spindle?

A: No, this specific listing is designed for BT30 and BT40 spindles. Please check our store for the BM series specifically rated for BT50 applications.

Q: How do I determine if I need the BM-65, BM-80, or BM-95?

A: The number refers to the outer diameter in millimeters. Please measure the inner diameter of your existing metal jaws or consult your machine's manual for the correct coupling size.
