Trane SHE5346 Sheave
The Trane SHE5346 Sheave is a heavy-duty, single-groove BK90H Sheave engineered for precision power transmission in commercial air handlers and ventilation systems. Constructed from close-grain cast iron, this fixed-pitch component features a combination groove design optimized for 4L, A, 5L, and B section V-belts. This bushed-type pulley requires an H-series split taper bushing for secure shaft mounting, accommodating bore sizes ranging from 0.38 to 1.5 inches. To minimize vibration and extend the service life of high-RPM blower motors, each unit is statically balanced and finished with a corrosion-resistant powder coating. Whether you are replacing a worn FHP bushed sheave or performing a full drive-train overhaul, maintain OEM specifications across Trane SHE5346, SHE05346, and Browning BK90H cross-references to ensure consistent RPM ratios. For contractors, prioritizing HVAC drive maintenance with high-tolerance sheaves prevents premature belt failure and ensures maximum efficiency in fractional horsepower applications.
Key Benefits:- Universal Compatibility: The combination groove supports 4L, 5L, A, and B belt profiles, offering versatility for various drive configurations.
- Superior Balancing: Statically balanced machining reduces parasitic vibration, protecting motor bearings and reducing audible noise.
- Durable Construction: High-tensile cast iron and a powder-coated finish provide high resistance to wear and environmental corrosion.
- Secure Mounting: Utilizes an H-series split taper bushing for a concentric, slip-free grip on the driving shaft.
What is the difference between the SHE5346 and a standard BK90 sheave?
The "H" suffix in BK90H signifies a bushed-bore design. Unlike the "BK90" which uses a fixed-bore with a setscrew, the SHE5346 requires an H-series bushing to match the specific shaft diameter of your blower motor.
How do I know if my sheave needs replacement?
Inspect the grooves for "U-shaped" wear or thinning side walls. A worn V-belt pulley causes belt slippage, heat buildup, and squealing, which significantly reduces the efficiency of the HVAC blower system.
Can I use this sheave with different belt types?
Yes, this BK-series sheave is specifically designed to accept both A and B section belts (including 4L and 5L variants), providing flexibility for field adjustments and belt-driven air handler repairs.
