Browning BK70X 1 7/16 Sheave
The Browning BK70X 1 7/16 is a heavy-duty, single groove cast iron sheave engineered for demanding HVACR power transmission applications. Featuring a 6.75" outside diameter and a precise 1-7/16" fixed bore, this component is designed for maximum concentricity and reduced vibration in high-torque environments. This BK cast iron sheave is versatile, compatible with 4L, 5L, A, and B series belts, allowing technicians to standardize inventory across various belt profiles. The high-grade cast iron construction ensures superior wear resistance and heat dissipation compared to pressed steel alternatives, maintaining belt tension and alignment during continuous operation. For contractors looking to optimize V-belt drive efficiency, the BK70X provides the rigid performance needed for air handlers, refrigeration condensers, and industrial fan assemblies. Proper installation requires checking alignment with the 1-7/16 inch shaft to prevent premature bearing wear and belt fatigue.
Key Benefits- Multi-Belt Compatibility: Engineered to accept A and B section belts along with 4L and 5L fractional horsepower belts.
- Durable Cast Iron Build: Provides high tensile strength and longevity for HVAC blower motor pulleys.
- Precision Machined Bore: The 1-7/16" fixed bore includes a standard keyway and setscrew for secure shaft seating.
- Optimized Heat Dissipation: Heavy-duty iron material draws heat away from the belt, extending the service life of the drive system.
What is the pitch diameter of the Browning BK70X?
The pitch diameter varies by belt type: it is approximately 5.8" for A belts and 6.2" for B belts, ensuring proper mechanical drive ratios.
Does this sheave require a separate bushing?
No, the BK70X features a fixed bore design pre-machined to 1 7/16 inches, eliminating the need for separate H-series bushings.
Can I use this for high-static pressure fan applications?
Yes, the Browning BK series is frequently used in high-static HVAC systems where rigid power transmission and minimal runout are required.
