Part Code: RS40-1B-30T
Part Name: Simplex Sprocket for Wimpy Snowblower
Part Name: Simplex Sprocket for Wimpy Snowblower
Part Code: RS40-1B-30T
Usage: Drives auger or impeller in Wimpy snowblower by heavy-duty #40 roller chain.
Application of Wimpy Snowblower Auger/Impeller Drive Sprocket
Built for Reliable Snow-Clearing Power Transmission:
Engineered for Wimpy snowblower machines, this sprocket drives the auger or impeller mechanism through a #40 roller chain system. It ensures efficient power transfer from the engine or gearbox to the snow-moving components for steady, uninterrupted operation.
Optimized for Cold, Abrasive & High-Load Winter Conditions:
Designed to perform in harsh winter environments where snow, ice, and grit demand consistent torque, balanced speed, and strong mechanical endurance. Ideal for auger and impeller assemblies that face continuous rotation, resistance, and heavy intake loads.
Trusted in Snowblower Mechanisms for Precision & Durability:
Widely used in consumer and commercial snowblower units requiring dependable, long-life sprockets. Its Type-B hub design offers secure mounting and simplified shaft alignment, while optional hardened teeth enhance wear resistance.
Summary
A robust, cold-ready sprocket developed for Wimpy snowblower auger and impeller systems. It delivers smooth power transmission, reliable torque output, and durable performance in challenging winter clearing conditions.
