Source1 2815208000 Fixed Sheave 1 Groove 1 Inch Bore AK64

Product Description

The Source1 2815208000 is a fixed sheave designed for use in HVAC blower and fan drive systems. This single-groove sheave features a 1 inch bore and is compatible with AK64 belt sizing. Fixed sheaves are a core component in belt-driven HVAC systems, where they work alongside a variable-pitch or matching fixed sheave to transfer rotational power from a motor shaft to a blower wheel or fan assembly. Because the sheave diameter is set and does not adjust, it delivers a consistent drive ratio, which is ideal for applications where airflow and motor speed have already been properly balanced and calibrated. HVAC technicians and mechanical contractors use fixed sheaves when replacing worn or damaged pulleys during routine maintenance or system retrofits. The AK64 designation refers to the outside diameter and groove profile, making it compatible with standard A-section V-belts. Proper sheave selection is critical for maintaining design airflow in air handling units, package units, rooftop units, and split systems. A correctly matched sheave and belt combination reduces slippage, minimizes vibration, and extends the service life of both the belt and motor bearings. The 1 inch bore fits directly onto a standard motor or blower shaft of the same diameter. When installing, technicians should verify shaft diameter, ensure the sheave is properly aligned using a straightedge or laser alignment tool, and torque the setscrew to manufacturer specification to prevent shaft slippage. The Source1 2815208000 is a straightforward, reliable replacement part for commercial and residential HVAC belt drive applications requiring a single-groove fixed sheave with a 1 inch bore.
