Browning 1VP68X 1 3/8 Sheave
The Browning 1VP68X 1 3/8 Sheave is a precision-engineered variable pitch pulley designed for high-performance HVACR air handling units and industrial motor drives. Constructed from high-grade cast iron, this single-groove component features a 6.55-inch outside diameter and a 1 3/8-inch fixed bore with a standard keyway. Engineered for versatility, it supports an adjustable datum diameter range of 4.9 to 6.4 inches, allowing technicians to fine-tune fan speed adjustment and system CFM without replacing the motor or drive. This heavy-duty sheave is compatible with a wide range of power transmission belts, including 4L, A, AX, 5L, B, BX, and BV belt profiles. Its robust construction ensures long-term concentricity and minimizes vibration in belt-driven systems. Use this sheave where precise belt tensioning and speed control are required for commercial ventilation or refrigeration condenser fan applications.
Key Benefits
- Precision Machined Cast Iron: Provides superior durability and heat dissipation compared to stamped steel alternatives.
- Variable Pitch Flexibility: Allows for field-adjustable sheave diameter changes to balance airflow and optimize motor load.
- Broad Belt Compatibility: Designed to work seamlessly with both A and B section V-belts for maximum application versatility.
- Fixed Bore Stability: The 1 3/8-inch bore with integrated keyway ensures a secure, slip-free attachment to the motor shaft.
Common Questions
How do I adjust the pitch on the Browning 1VP68X?
Loosen the set screws on the adjustable flange and rotate the flange to the desired pitch diameter, ensuring the moving parts are properly secured before operation.
What is the maximum RPM for this sheave?
This cast iron sheave is balanced for standard industrial motor speeds; however, always verify the maximum rim speed does not exceed 6,500 feet per minute.
Can I use this with a cogged AX belt?
Yes, the 1VP68X is fully compatible with AX and BX cogged belts, which often provide better efficiency and flexibility over small pulley diameters.
