Genuine Thread Tension Spring - Blue (Part #131-38805). This color-coded OEM spring is specifically calibrated to provide a heavy tension range required for specific thread paths on Juki MO-series machines.
Key Features & Benefits
100% Genuine Juki Quality: Precision-manufactured to Juki's strict tension standards. Unlike generic "one-size-fits-all" springs, this OEM part maintains its calibrated resistance even during high-speed, 7,000+ SPM production.
Color-Coded (Blue): The blue marking identifies this as a heavy-duty tension spring, typically utilized for the Needle Thread or Chainstitch Needle paths where high-stability and firm thread control are required.
Firm Tension Stability: Engineered to provide a consistent pressure curve, allowing for precise adjustments that won't "creep" or loosen under intense machine vibration.
