Bobbin Case Towa M Size 100100 Longarm Replacement Bobbin Case
The Towa M Size Bobbin Case 100100 is a precision replacement bobbin case for M-size longarm machines. Having a spare or backup bobbin case is essential for production studios — a damaged or improperly tensioned bobbin case is one of the most common causes of stitching problems on longarm machines, and a replacement case allows immediate swap-out without machine downtime.
Frequently Asked Questions
- Why should a production longarm studio have a spare bobbin case?
- If the primary bobbin case is damaged, develops a burr, or loses its tension spring responsiveness, having a calibrated backup case eliminates the machine downtime that would otherwise occur. Production studios should have at least two calibrated bobbin cases.
- Is the Towa 100100 compatible with all M-size longarm machines?
- The Towa M-size bobbin case is compatible with M-size bobbin systems. Check current product specifications for specific machine model compatibility.
- Should I calibrate a new bobbin case before use?
- Yes — use a Towa TM-3 tension gauge to measure and adjust the new case to match your established tension setting before using it in production.
- How long do bobbin cases typically last?
- With normal care, many years of production use. Replace when the tension spring becomes weak, a burr develops on the case edge or hook area, or tension becomes inconsistent despite proper adjustment.
- Can multiple bobbin cases be set to different tensions for different thread types?
- Yes — advanced studios maintain multiple calibrated bobbin cases set to different tensions for different thread weights and types, allowing rapid switching between production setups.
