Browning AK46X3/4 Sheave
For veteran contractors looking to eliminate drive-train vibration in fractional horsepower (FHP) applications, the Browning AK46X3/4 Sheave is a trade-standard solution. This 4.45" outside diameter sheave is precision-machined from high-tensile gray cast iron, providing far superior wear resistance compared to stamped steel alternatives. As a fixed bore sheave with a 3/4" finished diameter, it features a factory-cut 3/16" x 3/32" keyway and a standard hollow head setscrew, allowing for immediate installation on blower motor shafts without the need for additional bushings.
The single groove AK46 is designed for maximum versatility, providing a precise fit for 3L, 4L, and A section V-belts. Each unit is statically balanced at the factory to ensure true-running performance, which is critical for extending the life of motor bearings and reducing decibel levels in air handling units. The cast iron V-belt pulley construction effectively dissipates heat, maintaining belt grip and preventing premature glazing during continuous-duty cycles. This HVAC blower pulley is the reliable choice for technicians replacing worn adjustable sheaves with a permanent, high-stability fixed-ratio drive.
Key Benefits:
- Precision Machined: Constructed from grade 35 cast iron for long-term dimensional stability and resistance to "dishing."
- Optimized Balance: Statically balanced to minimize harmonic vibration in fan and blower assemblies.
- Fixed Bore Logic: The 3/4" finished bore provides a high-torque connection with less runout than bushed sheaves.
- Multi-Belt Compatibility: Engineered to match the pitch and datum diameters of 4L and A section belts.
- Corrosion Protection: Finished with a durable phosphate coat to prevent seizing in high-humidity mechanical rooms.
Common Questions:
- Can I use an AX belt with this sheave? Yes, the groove profile is compatible with AX and Gripnotch belts, though standard 4L or A belts are frequently used for FHP applications.
- How does this affect my blower RPM? The 4.45" OD (4.20" Datum Diameter for A-belts) determines the output ratio; ensure your motor's sheave diameter aligns with the required CFM specifications.
- Does this include the key? No, while the 0.75" bore includes the standard keyway and setscrew, the keystock must be sourced separately.
