FAQ Guide — KHJ-MC141-02

SS8MM Feeder Pressure Cover (Stainless Steel, Silver/Gold Finish)

1. What is the KHJ-MC141-02 used for?

It is a stainless steel top pressure cover mounted on Yamaha SS8MM tape feeders. It presses down on the carrier tape, stabilizing its position during advancement to prevent misfeeds or component misalignment.

2. What is the difference between silver and gold versions?

Both versions are functionally identical. The silver/gold color difference is due to different surface treatments or plating batches. The gold version may have additional anti-oxidation or ESD properties, depending on the manufacturer.

3. Which feeders are compatible with this part?

Yamaha SS8MM feeders
Used on SMT platforms including YSM10, YSM20R, YS12, YG12, YG200, etc.

4. Which parts work with this pressure cover?

KHJ-MC140-00 – Pressure spring
KHJ-MC136-00 – Pressure lever arm
KHJ-MC134-00SS8MM / KHJ-MC135-00 – Tape drive gears beneath the cover
KHJ-MC10A-00 – Feeder base frame
KHJ-MC163-00 – Bracket supporting cover alignment

5. How does the pressure cover affect feeder performance?

The pressure cover:

Ensures stable tape contact with the drive sprockets
Prevents tape flutter or lift-off during feeding
Supports accurate component pickup and placement reliability

6. How can I tell if the cover needs replacement?

Replace the cover if:

It is bent, cracked, or warped
It no longer sits flat and fails to apply even pressure
Excessive tape slippage or misfeeds are observed

7. Is the pressure adjustable?

The pressure itself is controlled by the spring (KHJ-MC140-00) and the lever mechanism, not the cover. If pressure is inconsistent, check those parts as well.

8. Is this part interchangeable with wider feeder models (12mm, 16mm)?

No. The KHJ-MC141-02 is designed specifically for SS8MM feeders. Other widths use different pressure covers to accommodate wider tape tracks.

9. Does the material support ESD safety?

Yes. The stainless steel is typically anti-static treated or coated to meet SMT ESD safety standards.
