B-1411-552 Needle Bar Stud

This needle bar stud secures the needle bar assembly in position, keeping needle movement precise and correctly timed with the hook.

Fits

• Jack F4, F5, F6 single needle lockstitch machines
• JUKI single needle lockstitch machines

Why Replace It

A worn needle bar stud introduces play into needle movement, which can throw off needle-to-hook timing and cause skipped stitches or needle breakage.

अक्सर पूछे जाने वाले प्रश्न

Can a worn stud really cause skipped stitches?
Yes — even slight play in the needle bar changes the needle’s position relative to the hook at the critical moment of stitch formation.
