Carrier KR12HY160 Pulley
The Carrier KR12HY160 Pulley is a high-performance 2VP56 variable pitch sheave designed for precise HVAC blower speed adjustment and reliable power transmission. Engineered from durable cast iron, this double groove variable speed pulley supports a variety of belt sections including 3L, 4L, 5L, A, and B, making it a versatile component for industrial fan drives. With an outside diameter (OD) of 5.35 inches and a finished bore, it provides the mechanical advantage needed to fine-tune airflow balancing in commercial air handling systems. This genuine OEM replacement part fits popular units such as the 40RMQ016 and 50BB series, ensuring vibration-free power transfer and consistent system uptime. Technicians can rely on the 2VP series for heavy-duty service up to 25HP, allowing for significant revolutions-per-minute changes without replacing the entire drive assembly. Proper alignment and precise set screw torque are essential to maintain belt drive efficiency and prevent premature wear.
Key Benefits- Precise Speed Control: The variable pitch design allows for minute adjustments to the pitch diameter, enabling technicians to optimize system airflow and air balance easily.
- Robust Construction: Manufactured from Class 30 gray cast iron, providing superior resistance to the abrasive wear typically caused by HVAC V-belts and environmental debris.
- Universal Compatibility: Works seamlessly with A and B series belts, offering flexibility for different HVAC drive system configurations and motor shaft requirements.
- Balanced Performance: Machined for high-speed operation to minimize mechanical vibration, which extends the life of both the motor bearings and the blower assembly.
What belt types are compatible with the 2VP56 sheave?
This 2-groove pulley is designed to accommodate 3L, 4L, 5L, A, and B belt sections. For optimal performance, ensure both grooves are adjusted equally so the belts ride evenly and provide consistent torque transmission.
How do I adjust the pitch diameter on this Carrier pulley?
To adjust the pitch diameter, loosen the knurled setscrews on the adjustable flanges. Each turn of the flange typically changes the diameter by approximately 0.16 inches. Always secure the setscrews to the specified torque after adjustment to prevent drive slippage.
Why is the KR12HY160 classified as Non-Cancelable / Non-Returnable?
As a specialized factory authorized part, this item is sourced for specific HVAC commercial applications. Contractors should verify the bore size and OEM part number against the equipment nameplate to ensure compatibility before ordering.
Item is Non Cancelable / Non Returnable
