Dodge 455601 QD Sheave 2 Groove 2A13.2/B13.6 SK V-Belt Pulley 1850 RPM

Dodge 455601 QD Sheave 2 Groove 2A13.2/B13.6 SK V-Belt Pulley 1850 RPM

The Dodge 455601 is a 2-groove Quick Detachable (QD) V-belt sheave designed for use with Classical A and B section belts. It mounts via an SK-style QD bushing (sold separately), which allows fast installation and removal without special tools. Cast iron construction provides the durability and balance required for industrial power transmission applications. The stamped hub face confirms the designation 2A13.2/B13.6 SK and a maximum operating speed of 1850 RPM.

Applications

QD V-belt sheaves like the Dodge 455601 are standard components in industrial power transmission systems, used to transfer rotational power between a motor or engine shaft and a driven machine. The 2-groove configuration allows dual-belt drives, which distribute load across both belts and are common on fans, blowers, pumps, compressors, and conveyor drives where additional torque capacity or redundancy is needed. The SK QD bushing system — a Dodge-standard taper-lock design — is widely used in manufacturing plants, HVAC systems, and processing equipment because it mounts securely to a wide range of shaft sizes and can be removed and repositioned without damaging the shaft. Classical A and B section belts remain among the most common V-belt profiles in industrial service, making this sheave compatible with a broad range of existing drives. The approximately 13-inch diameter makes it suitable for moderate-speed reduction applications typical of general industrial machinery.
