Source1 2812364700 Fixed Single Groove Sheave 1 Inch Bore BK67

Product Description

The SOURCE1 2812364700 is a fixed single groove sheave with a 1 inch bore, designed for use in HVAC blower and fan drive assemblies. This sheave carries the BK67 designation, indicating its pulley diameter and bore size classification within the standard V-belt sheave system. Fixed sheaves like this one are used to establish a set speed ratio between the motor and the blower wheel. Unlike variable pitch sheaves, fixed sheaves provide a locked, non-adjustable groove angle, making them ideal for installations where the required fan speed is already determined and no further field adjustment is needed. HVAC technicians and mechanical contractors rely on fixed sheaves for their durability and consistent power transmission performance. The 1 inch bore accommodates a standard motor or blower shaft size commonly found in commercial and residential air handling units. This sheave is paired with a standard A or B section V-belt to transfer torque from the drive motor to the blower assembly. Proper sheave alignment and belt tension are critical to reducing wear and maintaining system efficiency. Replacing a worn or damaged sheave with a direct OEM-equivalent like the SOURCE1 2812364700 helps restore proper airflow and motor load balance. This component is a common service part for rooftop units, air handlers, and fan coil units across a wide range of equipment brands. HVAC service professionals should verify shaft diameter, belt section, and outside diameter compatibility before installation to ensure correct fit and system performance.

• Fixed single groove design provides consistent, non-adjustable speed ratio for reliable blower performance
• 1 inch bore fits standard motor and blower shaft sizes used in commercial and residential HVAC equipment
