Browning AK30X7/8 Sheave
The Browning AK30X7/8 Sheave is a precision-engineered cast iron V-belt pulley designed for consistent power transmission in fractional horsepower applications. Featuring a 7/8" finished bore with a standard keyway and set screw, this single groove sheave eliminates the need for additional bushings, allowing for direct mounting on motor or fan shafts. With a 3.05" outside diameter, it is optimized for 4L and A section belts, while also remaining compatible with 3L belts for lighter load requirements. Machined from close-grain cast iron and statically balanced to minimize vibration, this component ensures stable HVAC blower motor performance and reduces mechanical wear on bearings. Whether you are replacing a worn fixed bore sheave in a commercial air handler or a small industrial compressor, the AK30X7/8 provides the concentricity and grip necessary for high-efficiency drive systems and reliable belt tracking.
Key Benefits- Precision Machined Cast Iron: Constructed from high-quality close-grain cast iron for maximum wear resistance and thermal stability.
- Vibration-Free Operation: Statically balanced at the factory to ensure smooth rotation and extend the life of your motor and belts.
- Versatile Belt Compatibility: Designed to fit A, 4L, and 3L V-belts, offering flexibility for various drive configurations.
- Finished Bore Installation: Includes a 7/8" bore with a standard keyway and hex set screw for secure, immediate mounting.
What is the difference between Datum Diameter and Outside Diameter for this sheave?
The 3.05" Outside Diameter (OD) is the total edge-to-edge measurement. For calculation of drive ratios, technicians should refer to the Datum Diameter, which is approximately 2.46" for 3L belts and 2.80" for A section belts.
Can I use a Gripnotch belt with the AK30X7/8?
It is generally recommended by the manufacturer to avoid using gripnotch (cogged) belt ratings with "AK" sheaves that have bores 1" and under to maintain optimal surface contact and prevent premature belt fatigue.
Does this sheave require a separate bushing?
No, this is a fixed bore sheave. It is bored to size at 7/8" and is ready for direct installation on a matching shaft.
