Product Description
Worm Gear for Leather Stitch Machine
This worm gear drives feed timing on machines set up for leather and heavy-material stitching, handling the extra load that heavier materials put on the feed mechanism.
Fits
- Jack F4, F5, F6 single needle machines set up for leather/heavy stitching
Why Replace It
Worm gears wear faster under heavy-material loads. A worn gear causes feed timing to slip, leading to skipped stitches specifically on thick or leather material.
FAQ
Why does this wear faster than a standard gear?
Leather and heavy-material stitching puts significantly more mechanical load on the feed drive than standard fabric work, accelerating gear wear.
