Reznor 19111 Sheave
The Reznor 19111 is a high-performance AK 84-1 Sheave engineered specifically for heavy-duty HVACR applications. Designed for direct replacement in Reznor heating units, this single groove sheave facilitates precise power transmission within the blower assembly. Constructed from durable class 25 cast iron with a baked enamel finish, the 19111 sheave features an 8.25-inch outside diameter and a 1-inch finished bore. The integrated 1/4" x 1/8" keyway and hex setscrew ensure a secure, slip-free fit on the motor shaft, maintaining consistent belt-driven fan speeds. As a genuine OEM Reznor component, it eliminates the balancing issues and premature wear common with generic pulleys. This AK84-1 sheave is compatible with 3L, 4L, and A-section V-belts, making it a versatile hub for restoring optimal airflow and static pressure in commercial gas-fired heaters. For contractors performing preventative maintenance or diagnosing blower slippage, this cast iron pulley is the industry standard for reliable operational efficiency.
Key Benefits- Precise Power Transfer: The AK 84-1 design ensures consistent torque from the motor to the fan, preventing RPM loss.
- Industrial Durability: Machined from class 25 cast iron for high heat resistance and vibration dampening.
- Universal Belt Compatibility: Profiled to fit A-section, 3L, and 4L belts for maximum field flexibility.
- Vibration-Free Operation: OEM balanced to reduce bearing stress and extend the life of the blower motor.
What is the bore size for the Reznor 19111?
This sheave features a 1-inch finished bore equipped with a standard keyway and setscrew for secure shaft mounting.
Which Reznor models use the AK84-1 sheave?
It is widely used in Reznor gas-fired unit heaters and air handlers that utilize a belt-driven blower assembly.
Does this include the keyway?
Yes, the 19111 comes with a machined 1/4" x 1/8" keyway to ensure high-torque stability during startup and continuous operation.
