40-5 Clutch: The "Power Switch Hub" of Low-Power Models

The 40-5 Clutch is the "power switch hub" of low-power 40-5 models—it adopts a centrifugal structure design: when the engine speed reaches 1800r/min, centrifugal force pushes the clutch pad to expand outward, engaging tightly with the drive wheel, with a power transmission efficiency of 98%; at low speed, the return spring pulls the clutch pad to reset, enabling no-load startup to protect the engine.

Its clutch pad uses high-wear-resistant friction material, with a stable friction coefficient of 0.45 and a service life of 3000 hours (2x that of ordinary materials); the bracket is stamped from high-strength steel, resisting centrifugal force impact without deformation, adapting to high-frequency start-stop scenarios of low-power equipment.

In 40-5 engine use, old clutches are prone to power slipping (no load output, engine idling) due to friction pad wear and spring failure. After replacing this clutch, the stability of power transmission is fully restored, and the connection between equipment startup and operation is smoother.

Whether for power output of small generators or power drive of portable tools, the 40-5 Clutch can provide reliable power switching for 40-5 models with "precise engagement + high wear resistance" performance, being the core component for "efficient power transmission" of low-power equipment.
