The Belt Pulley 3V4122 is a QD bushed V-belt pulley designed for 3V belt sections, featuring 2 grooves with a pitch diameter of 4.12 inches and an outer diameter of 4.12 inches. It uses an SH series bushing and is manufactured from cast iron, providing durability for mechanical power transmission systems. The length through bore measures 1.25 inches, with a face width of 1.0938 inches, and supports a bushing bore range of 1/2 to 1-11/16 inches.
This pulley is compatible with keyway sizes ranging from 1/4 x 1/8 inches to 5/16 x 5/32 inches, depending on the bore diameter, ensuring secure fitment across applications. Cast iron is a standard material for such pulleys due to its high strength and wear resistance, while the QD bushing system allows for easy installation and removal. Typical applications include industrial machinery, agricultural equipment, and HVAC systems where reliable torque transfer is required.
Buyers for this pulley include OEMs and distributors sourcing components for power transmission assemblies. The pulley is suited for systems requiring precise alignment and consistent performance under load. Confirm the exact bushing size and keyway dimensions with the supplier to match your shaft specifications, as these are critical for proper fitment and operation.

Before ordering, verify the pulley’s pitch diameter and bushing bore range to ensure compatibility with your shaft and belt system. Confirm the keyway dimensions, as these are critical for securing the pulley and preventing operational failures. Request a material test report to validate the cast iron’s hardness and composition.
Discuss logistics such as lead time, which may vary based on order volume and customization requirements. Clarify Incoterms, particularly whether the supplier offers FOB or CIF terms from a Chinese port. Payment terms should also be confirmed, as these often depend on the buyer’s credit history and order size.
Inspect the pulley upon arrival for dimensional accuracy, surface finish, and material integrity. Check the keyway alignment and bushing fitment to avoid misalignment during installation. Request a conformity certificate to ensure the product meets the specified standards and your application’s technical demands.
