Browning 2B68SDS Sheave

The Browning 2B68SDS Sheave is a precision-engineered two-groove Q-D (Quick Detachable) sheave designed for rugged commercial HVACR applications. Constructed from high-grade cast iron, this sheave features a 7.15" outside diameter and is balanced to ensure minimal vibration in high-torque environments. Engineered for versatility, it is compatible with both A and B series belts (including 4L and 5L variants), providing reliable power transmission across diverse motor and fan configurations. The component utilizes an SDS series bushing, allowing for a secure, slip-free fit on various shaft diameters while facilitating easier installation and removal compared to standard fixed-bore pulleys. By maintaining strict pitch diameter tolerances, the 2B68SDS optimizes belt drive efficiency and reduces tangential stress on the drive system, ensuring mechanical stability in demanding air handling or refrigeration setups. Rely on this Browning sheave for consistent RPM management and industrial-grade durability.

Key Benefits:

• Compatible with A, B, 4L, and 5L belts for maximum application flexibility.
• Features a 7.15" O.D. and 6.8" pitch diameter (B) for precise drive ratios.
• Designed for SDS Q-D bushings, offering superior clamping force and easy alignment.
• High-grade cast iron construction provides excellent heat dissipation and wear resistance.
• Dynamically balanced to reduce harmonic vibration and extend bearing life.

Common Questions:

Which bushing is required for this sheave?
The 2B68SDS requires an SDS Series Q-D bushing. Ensure you select the bushing size that matches your motor or blower shaft diameter.

Can I use this sheave with BX or AX cogged belts?
Yes, this sheave is compatible with AX and BX cogged belts, which can often improve drive efficiency and heat dissipation in tighter configurations.

What is the difference between the 2B68SDS and a fixed bore sheave?
The Q-D design allows for interchangeable bushings, meaning you can adapt the same sheave to different shaft sizes without replacing the entire unit, providing a more secure "press fit" than set-screw bores.
