Genuine Thread Tension Rubber Washer (Part #131-38003). This authentic OEM component is a critical "buffer" within the tension assembly of Juki MO-series industrial overlockers, designed to provide the necessary friction and vibration dampening for high-speed sewing.
Key Features & Benefits
100% Genuine Juki Quality: Manufactured from a specialized oil-resistant rubber compound. Unlike generic hardware-store washers, this OEM part will not perish, swell, or become "gummy" when exposed to industrial lubricants.
Vibration Dampening: Acts as a shock absorber for the tension spring and disks, preventing "tension jump" during the high-frequency oscillations of 7,000+ SPM production.
Precise Friction Control: Provides the exact amount of grip required to keep the tension nut from "creeping" or loosening due to machine vibration.
