Browning 2TB74 Sheave
The Browning 2TB74 Sheave is a precision-engineered two-groove TB Gripbelt sheave designed for high-performance power transmission in commercial HVACR and industrial blower applications. With a 7.75" outside diameter and a 7.4" pitch diameter for B-belts, this cast iron pulley is dynamically balanced for standard operating speeds and utilizes Q1 Series split taper bushings to ensure a secure, concentric fit on the shaft. It is engineered for versatile field installation, offering compatibility with A, AX, B, and BX V-belts, allowing contractors to standardize inventory while maintaining peak drive efficiency. The rugged construction minimizes vibration and extends belt life, making it a reliable component for heavy-duty fan motors and air handling units requiring consistent V-belt pulley alignment and torque transmission.
Key Benefits:- Compatible with A, AX, B, and BX belt profiles for maximum field flexibility.
- Utilizes Q1 split taper bushings for a rigid, concentric grip that prevents shaft marring.
- Precision-machined from gray cast iron for durability in high-static pressure environments.
- Two-groove design allows for increased horsepower capacity and redundancy in critical air-moving systems.
- Static balance ensures quiet operation and reduces mechanical stress on motor bearings.
What is the difference between pitch diameter and outside diameter for this sheave?
The Browning 2TB74 has a 7.75" outside diameter, but the effective pitch diameter varies based on the belt used: 7.0" for A-belts and 7.4" for B-belts. Correct calculations are essential for maintaining designed CFM outputs.
Which bushing is required for installation?
This sheave requires a Q1 series bushing. These must be ordered separately to match your specific motor or blower shaft diameter.
Can this be used with notched belts?
Yes, this sheave is fully compatible with AX and BX cogged V-belts, which offer higher efficiency and better heat dissipation than standard wrapped belts.
