Genuine Thread Tension Spring - Red (Part #131-37807). This color-coded OEM spring is specifically calibrated to provide the medium-to-heavy tension range required for specific thread paths on Juki MO-series machines.
Key Features & Benefits
100% Genuine Juki Quality: Manufactured to exact tension specifications. Unlike generic springs, this OEM part maintains its calibrated resistance even under the heat of 7,000+ SPM production.
Color-Coded (Red): The red marking identifies this as a specialized tension spring, typically used for the Needle Thread or Lower Looper paths where higher tension stability is required.
Consistent Pressure: Engineered to provide a linear tension curve, allowing for micro-adjustments that stay put once the tension nut is set.
