Jack 20101202 Presser Bar for JK-804D / JK-805D

The Jack 20101202 Presser Bar is a genuine part for the Jack JK-804D and JK-805D overlock sewing machines. It’s the vertical bar that guides the presser foot up and down, keeping consistent pressure on the fabric as it feeds under the needles. Best for garment factories running JK-804D/805D lines where the presser bar has bent, developed play, or is causing uneven foot pressure.

• Built for the JK-804D and JK-805D overlock machine range
• Precision-ground for smooth vertical travel with minimal play

उपयोग के मामले

How To Replace This Presser Bar

1. First, switch off the machine and remove the presser foot.

6. Finally, run a test seam to confirm even foot pressure before returning to full production.

अक्सर पूछे जाने वाले सवाल

How do I know the presser bar needs replacing rather than just adjusting?

A visibly bent bar, uneven pressure on one side of the foot even after adjusting the pressure screw, or noticeable play when you wiggle the foot by hand all point to the bar itself rather than a simple tension adjustment.

Does this fit both the JK-804D and JK-805D?

Yes, Jack shares the 20101202 presser bar across the JK-804D and JK-805D since both machines use the same presser assembly geometry.

Can a bent presser bar be straightened instead of replaced?

A bent bar can sometimes be straightened, but it tends to bind in its guide bushings afterward since the metal has been stressed unevenly. For smooth, lasting travel, replacement is the more reliable fix.

Will I need to readjust anything else after fitting this bar?

Usually just a check of the presser foot pressure setting, since a new bar may sit slightly differently than the worn one it replaces. No timing adjustment is needed for this part.

Does this ship with COD and pan-India delivery?

Yes, this part ships pan-India with cash-on-delivery available on eligible orders, along with GST billing for business buyers.
