Description
SM Oscillating Rockshaft Free Size
This sewing machine oscillating-rockshaft helps control things like:
- The rockshaft oscillates (rocks back and forth).
- Needle bar movement (vertical up/down)
- Feed dog motion (moving fabric under the needle)
- Hook timing (in machines with oscillating hook systems)
It plays a key role in syncing these actions so the machine can form stitches properly.
