Genuine Juki Lower Looper Support Arm Assembly (Part #131-32550). This authentic OEM assembly is the critical structural link that drives and stabilizes the lower looper, ensuring the exact timing required for high-speed industrial stitching.

High-Performance Looper Stability
The lower looper support arm must endure millions of rapid reciprocating cycles without losing its alignment. The 131-32550 is manufactured to Juki’s rigorous engineering standards, providing a rigid, vibration-resistant foundation that prevents the "looper play" that leads to skipped stitches and catastrophic needle strikes.

Why Choose the Genuine 131-32550 Assembly?
Factory-Calibrated Timing: Designed to match the exact stroke and arc of Juki industrial overlockers, reducing the setup time required for mechanical timing adjustments.

Superior Vibration Dampening: Cast from high-strength industrial alloy to absorb the high-frequency oscillations of 7,000+ RPM operation.

Precision Bushing Fit: Features perfectly machined pivot points to ensure fluid motion and minimize heat buildup in the drive mechanism.

Long-Term Durability: Built to withstand the constant stress of heavy-duty production, outlasting generic "will-fit" arms that can warp or wear prematurely.
