DSH2-100-22 Rotary Hook Set for Double Needle Sewing Machine

The DSH2-100-22 rotary hook set for double needle sewing machines is a replacement rotary hook assembly designed to support thread loop pickup and lockstitch formation in compatible industrial sewing machines. It suits sewing machine maintenance and replacement requirements in tailoring workshops, garment manufacturing units, and heavy-duty stitching operations.

This product comes as 1 piece without a bobbin case. Before ordering, check your existing hook’s part number, mounting arrangement, and machine model to confirm compatibility.

What Is the DSH2-100-22 Hook Set Used For?

The rotary hook plays an important role in lockstitch formation. It catches the needle thread loop and works with the bobbin thread mechanism to form stitches during sewing.

A compatible replacement hook can help restore stitching performance when the original part becomes worn, damaged, or unreliable. It is useful for maintenance work on industrial machines that sew two parallel rows of stitches.

Key Features of the DSH2-100-22 Rotary Hook Set

• Replacement hook assembly: Designed for compatible industrial sewing machine applications.
• Thread loop pickup: Supports the hook’s role in forming consistent lockstitches.
• Double-row stitching applications: Intended for suitable double-needle sewing machine configurations.

मशीन अनुकूलता

The DSH2-100-22 part number is associated with selected Mitsubishi and Highlead industrial sewing machine models in published parts references. Compatibility should be confirmed against the exact machine model and existing hook assembly before purchase.

Suitable Fabrics and Applications

The correct hook configuration depends on the sewing machine and its intended application. Compatible machines may be used for stitching applications involving:

• डेनिम: Jeans and workwear seams.
• कपास: Shirts, uniforms and everyday garments.
• पॉलिएस्टर: Garments and uniform production.
• Canvas: Suitable bags and workwear, where supported by the machine setup.
• Other medium or heavy materials: Subject to the machine’s rated sewing capacity and needle-thread setup.

The hook alone does not determine fabric compatibility. Needle selection, thread size, machine timing, and the complete sewing setup also affect stitch quality.

How to Replace the Rotary Hook

1. Switch off the sewing machine and disconnect its power supply.
2. Remove the necessary covers and components according to the machine’s service manual.
3. Identify the existing hook and compare its part number, shape, and mounting arrangement with the replacement.
4. Install the hook according to the manufacturer’s service instructions.
5. Check hook timing, needle clearance, and thread movement before resuming production.
6. Turn the handwheel manually to check for interference, then test the stitch on scrap fabric at a low speed.

For best results, ask a qualified sewing machine technician to install and time the hook if you are unfamiliar with the machine’s mechanism.

अक्सर पूछे जाने वाले सवाल

2. Does this hook set include a bobbin case?

नहीं। इस सूची में शामिल है one hook set without a bobbin case. If your machine requires a separate bobbin case, check whether your existing case can be reused or whether another part is needed.

3. Is the DSH2-100-22 compatible with Mitsubishi sewing machines?

Only selected models. Parts references list the DSH2-100-22 against certain Mitsubishi machines, including DU-100-22 and some LU2-series models. Confirm the exact model and hook configuration before purchasing.

4. Will this hook set fit every double-needle lockstitch machine?

No. Double-needle machines can use different hook designs and mounting arrangements. Match the part number and physical configuration instead of relying on the machine type alone.

5. Can a worn rotary hook cause skipped stitches?

Yes. A damaged or worn hook can contribute to skipped stitches, thread damage, or inconsistent stitch formation. However, needle condition, hook timing, thread tension, and other machine components can cause similar symptoms.
