Browning 2B94SK 2-Groove V-Belt Sheave 9.75" OD SK QD Bushed A/B Belt

The Browning 2B94SK is a fixed-pitch, two-groove V-belt sheave designed for use with A, 4L, AX, B, 5L, and BX belt sections. Featuring a 9.75-inch outside diameter and an SK-series Quick Detach (QD) bushed bore, this sheave delivers reliable, high-efficiency power transmission across a wide range of industrial and mechanical drive applications.

Built from close-grain cast iron, the 2B94SK is precision-machined to tight tolerances for accurate belt alignment and smooth operation. The combination groove design allows both A and B section belts to be run interchangeably, providing flexibility in pitch diameter and horsepower capacity.

Key Features:

• 2 Grooves — accepts A/B combination belt sections (4L, A, AX, B, 5L, BX)
• 9.75" Outside Diameter — pitch diameter 9.20" (A belt) / 9.40" (B belt)
• SK Series QD Bushing — bushing bore range 0.500" to 2.625"; bushing sold separately
• Close-grain cast iron construction — precision machined for closest possible tolerances
• Face width: 1.750" | Length through bore: 1.9375"
• Keyway sizes: multiple keyway options included across full bore range (1/8×1/16" through 5/8×5/16")
• Arm style: Type D3 | Manufacturer internal number: 1004357
• QD two-component design — replace only the worn component without discarding the entire assembly

The SK Quick Detach bushing system simplifies installation and removal, and supports a broader range of shaft bore sizes compared to a fixed-bore sheave. Note: SK bushing is sold separately. This sheave is statically balanced and finished for corrosion resistance, making it suitable for demanding drive system environments.
