Genuine hardened steel needle bar stud for Juki DDL-5550 L/S series sewing machines. Holds the needle bar on correct axis for precise up/down movement and accurate needle penetration.
The Needle Bar Stud for the Juki DDL-5550 is the precision-machined component that aligns and supports the needle bar, ensuring it moves on the exact correct axis during each stitch cycle.
The needle bar stud determines the needle's lateral alignment. A worn stud causes the needle bar to wobble slightly, resulting in needle deflection, needle breakage, skipped stitches, and premature wear on the needle plate hole. This is particularly critical on the Juki DDL-5550 which runs at up to 5,500 stitches per minute.
This stud is specified for the Juki DDL-5550 L/S model. L/S refers to the long/short shaft configuration. Please confirm your exact model variant before ordering.
Hardened steel needle bar stud for Juki DDL-5550 L/S (Long Shaft / Short Shaft variant). Precision-machined for correct needle bar positioning and stroke.
L/S on Juki DDL-5550 refers to the shaft length variant of the machine. Confirm whether your machine is the L (long shaft) or S (short shaft) variant before ordering this stud.
Yes. A worn needle bar stud allows the needle bar to wobble laterally, which can cause the needle to strike the needle plate hole edge, resulting in needle breakage.
