Replacement Bobbin Cases for Embroidery Machines

The case that holds the bobbin is called a bobbin case. It is a small, spring-tensioned housing that fits into the machine's hook assembly and controls the tension of the lower thread. On commercial embroidery machines like the Xtreme Tech XTPro and Happy Japan series, the bobbin case is a critical consumable part that should be inspected and replaced regularly to maintain stitch quality.

Dr. DTG stocks OEM replacement bobbin cases compatible with Xtreme Tech XTPro models (1401Ci, 1501 IPX, 1502 IPX, 1504 IPX, XLS) and Happy Japan machines (HCH Plus, HCD3E-X1501, HCR3-1504-45). Contact Dr. DTG with your machine model and serial number to confirm the correct part for your unit.

You can order a replacement bobbin case by submitting a parts ticket at drdtg.com/submit-ticket with your machine model and serial number, or by calling Dr. DTG directly at 714-770-0969. You can also visit in person at 588 Explorer St., Brea, CA 92821 during business hours, Monday through Friday, 9AM–5PM.

On high-production commercial embroidery machines, bobbin cases should be inspected regularly for wear, burrs, or inconsistent thread tension. A common recommendation is to replace the bobbin case every 3–6 months under heavy production use, or immediately if you notice skipped stitches, thread breakage, or inconsistent tension that cannot be resolved through adjustment.
