KV7-M2651-00 KHW-M2654-00 YSM10 YSM40R Y-axis anti-collision rubber pad

Product Introduction – KV7-M2651-00 / KHW-M2654-00

Y-axis Anti-Collision Rubber Pad for Yamaha YSM10 / YSM40R

Overview

The KV7-M2651-00 and KHW-M2654-00 are Y-axis anti-collision rubber pads designed specifically for Yamaha YSM10 and YSM40R high-speed modular mounters. These pads are mounted on the Y-axis mechanism to absorb impact and prevent mechanical damage during high-speed movement or unexpected mechanical interference.

Features

High-impact absorption: Made from industrial-grade rubber to reduce mechanical stress during collision or overrun.
Yamaha OEM Design: Precisely manufactured to fit the YSM10 and YSM40R machines.
Durable and wear-resistant: Designed for long-term use under continuous operation.
Easy replacement: Simple installation during routine maintenance without disassembling major structures.

Applications

Installed on the Y-axis slider or stopper of the placement head rail.
Prevents metal-to-metal contact in limit situations, extending the life of linear guides and servo systems.
Commonly replaced in machines running high-speed, high-frequency movement cycles.

Compatible Models

FAQ Guide – YSM10 / YSM40R Y-axis Anti-Collision Rubber Pad

Part Numbers: KV7-M2651-00 / KHW-M2654-00

1. What is the function of this rubber pad?

It absorbs impact at the end of the Y-axis travel to prevent mechanical collision between moving parts, protecting the rail, servo motor, and head assembly.

2. Which machines is it used on?

Specifically designed for Yamaha YSM10 and YSM40R high-speed placement machines.

3. Where is it installed?

The rubber pad is mounted at the end of the Y-axis rail or guide mechanism, acting as a stopper to cushion overtravel or emergency stops.

4. How do I know if the rubber pad needs replacement?

Look for visible wear, cracks, flattening, or if the machine makes unusual impact noises during Y-axis homing or limit motion. These indicate the pad has lost its damping effect.

5. What happens if it's not replaced when worn?

Failure to replace a worn pad can result in:

Damage to linear rails or sliders
Decreased motion accuracy
Excess vibration or mechanical noise
Potential Y-axis alignment issues

6. Are both KV7-M2651-00 and KHW-M2654-00 required?

They may be used as left and right stoppers or depending on the machine version. Refer to machine documentation or exploded views for your specific model.

7. Can I use third-party rubber pads?

It’s not recommended. Use genuine Yamaha parts to ensure the correct hardness, fit, and durability.

8. Is special calibration needed after replacing the pad?

Generally, no calibration is required, but it's good practice to check axis homing and limit detection after installation.

9. How often should it be checked or replaced?

Inspect during scheduled preventive maintenance—typically every 3–6 months depending on machine usage.

10. Where can I get these parts?

They are available through authorized Yamaha distributors or certified SMT parts suppliers.
