Trane SHE5939 Sheave
When you're out in the field servicing a commercial air handler or a belt-driven condenser, you need a replacement sheave that holds its settings under load. The Trane SHE5939 is an industrial-grade, single groove variable pitch sheave designed for precision airflow balancing and reliable power transmission. Cast from high-quality gray cast iron, this 1VP40 model sheave features a 3.75-inch outside diameter and a 7/8-inch fixed bore with a standard ANSI keyway and dual knurled set screws for a secure, slip-free shaft lock.
For technicians dialing in static pressure, the variable pitch design offers an adjustable range from 2.3 to 3.8 inches, allowing you to fine-tune blower speeds without swapping out the entire pulley. This component is optimized for 3L, 4L (A), and 5L (B) V-belt sections, ensuring maximum flexibility across broad HVACR motor drive applications. Whether you are replacing a worn fan pulley or upgrading a belt drive system, the SHE5939 provides the thermal stability and mechanical durability required for continuous-duty industrial environments.
Key Benefits
- Precision Speed Control: The variable pitch diameter allows for field-adjustable RPM settings to meet specific airflow requirements.
- Bore Security: The 7/8" fixed bore includes a set screw over the key and a second at 90 degrees to prevent shaft galling and vibration.
- Heavy-Duty Construction: Cast iron body ensures superior wear resistance and heat dissipation compared to stamped steel alternatives.
- Universal Belt Support: Compatible with A and B section V-belts, making it a versatile OEM replacement part for Trane and American Standard units.
Common Questions
- What is the adjustment range of this sheave? This Trane drive component features a 2.3 to 3.8 variable pitch, providing a significant range for motor speed adjustments.
- Does this sheave include the key? While it features a standard ANSI keyway, the 7/8" shaft key is typically sold separately or retained from the existing motor shaft.
- Is this sheave balanced for high-RPM use? Yes, these cast iron sheaves are statically balanced at the factory to minimize harmonic vibration in high-velocity blower assemblies.
