Browning 2B70SK Sheave
The Browning 2B70SK Sheave is a heavy-duty two-groove Q-D sheave engineered for demanding HVACR and industrial drive applications. Constructed from high-grade, close-grain cast iron, this 7.35" outside diameter sheave is precision-machined to ensure minimal vibration and optimal power transfer. It features a combination groove design, making it fully compatible with both A and B series belts (including 4L and 5L sections), providing technicians with significant drive flexibility and varying pitch diameters for different torque requirements. Specifically designed for use with SK series bushings, this QD bushed sheave allows for a split taper secure fit on shafts ranging from 0.5" to 2.625". With a 7.0" datum diameter for B belts and 6.6" datum diameter for A belts, the 2B70SK provides a reliable, split-taper bushing interface that simplifies installation and removal in tight mechanical rooms. This cast iron V-belt pulley is factory-balanced and phosphated to resist corrosion in high-moisture environments.
Key Benefits- Dual-Groove Performance: Increases torque capacity and provides redundancy for critical power transmission systems.
- Universal Belt Compatibility: Browning combination grooves accommodate A, B, 4L, and 5L V-belts, reducing the need for multiple replacement parts.
- SK Bushing Versatility: Utilizes a Quick-Detachable (Q-D) system for a secure, concentric fit across a wide range of shaft diameters.
- Precise Tolerances: Close-grain iron construction ensures dynamic balance and reduces wear on motorized equipment.
Which bushing is compatible with the Browning 2B70SK?
This sheave requires a Browning SK series bushing. The specific bore size must be selected based on your motor or fan shaft diameter.
Can I use both A and B belts in this sheave?
Yes, the 2B70SK features combination grooves designed to seat A (4L) and B (5L) cross-section belts effectively.
What is the difference between outside diameter and pitch diameter for this sheave?
While the outside diameter (OD) is 7.35", the pitch diameter varies by belt type: it is 6.8" for A belts and 7.3" for B belts, which is critical for calculating correct drive ratios.
