Browning 2B5V86 Sheave

The Browning 2B5V86 Sheave is a high-performance, precision-engineered component designed for heavy-duty HVACR and industrial blower applications. This 2-groove cast iron sheave features a versatile combination groove design, allowing technicians to utilize A, B, and 5V belt sections within a single drive assembly. Built with a significant 8.88" outside diameter, the 2B5V86 is optimized for high horsepower transmission while maintaining exceptional balance and reducing system vibration. This unit requires a B Series Split Taper Bushing to ensure a secure, key-to-key drive connection between the shaft and the hub, effectively eliminating torque-related stress on cap screws.

For contractors managing multi-belt air handlers or cooling tower fans, the Browning B5V series simplifies inventory by consolidating classic and high-capacity drive requirements. The spoked construction utilizes Finite Element Analysis to maximize structural integrity while reducing overall weight, ensuring the Browning 2B5V86 delivers consistent pitch diameters across 4L, 5L, AX, BX, and 5VX belt profiles. This robust V-belt pulley is the standard for technical reliability in demanding environments, offering 5V performance with B-groove economy.

• Universal Belt Compatibility: The unique combination groove accommodates A, AX, B, BX, 5V, and 5VX belts, providing maximum flexibility for field replacements.
• Split Taper Bushing System: Utilizes B series bushings for a true concentric fit, ensuring high torque capacity and easy installation on varying shaft sizes.
• Industrial Durability: Machined from high-grade cast iron for superior wear resistance in high-duty cycle HVACR applications.
• Optimized Performance: Precision balanced to minimize vibration, extending the service life of bearings and connected drive components.

Common Questions

What is the OD and datum diameter for the 2B5V86?
This sheave has an 8.88" outside diameter. The datum diameter varies significantly based on the belt used: 8.20" for A belts and 8.60" for B belts, with a 5V pitch diameter of 8.70".

Can I use banded belts with this sheave?
No, B5V sheaves utilize specific groove spacing that is not compatible with banded belt configurations. Always use individual belts in each groove.

Which bushing is required for installation?
The 2B5V86 requires a B series Browning Split Taper Bushing. Ensure the bushing bore size matches your motor or blower shaft diameter.
