Description
AMEC BK-Series pulleys (sheaves) are durable, cast-iron V-belt pulleys designed for industrial power transmission. They are highly versatile and engineered to accommodate multiple belt sizes, making them a standard choice for motors, pumps, HVAC systems, and manufacturing equipment.
Key Features
- Versatile Compatibility: BK pulleys are designed to be used with a wide variety of belt profiles, including A (4L), B (5L), and BX V-belts.
- Cast Iron Construction: Manufactured from high-quality, durable gray cast iron, making them rugged and capable of handling demanding industrial workloads.
- Multiple Groove Options: Available in both single-groove (e.g., BK32H, BK50H) and double-groove (e.g., 2BK36, 2BK80H) configurations to adjust power transfer and speed.
- Bushing Mounting System: Many models in this series use "H" style Quick Detachable (QTL) taper bushings, allowing for easy installation, precise centering, and effortless removal without damaging the equipment shaft.
Why Choose BK Series?
Compared to lighter-duty AK pulleys, which are strictly limited to lighter fractional horsepower applications, the BK-Series provides heavier-duty capability. Because they support heavy-duty B-section belts, they can transfer higher torque and are excellent for frequent stop-and-start applications commonly found in high-pressure wash pumps and commercial blowers.
