Browning AK64X7/8 Sheave
The Browning AK64X7/8 Sheave is a precision-engineered fixed bore pulley designed for light-duty laboratory and industrial HVACR applications. Cast from high-grade gray cast iron, this single groove AK sheave features a 6.25" outside diameter (O.D.) and is machined to accommodate a 7/8" shaft. It is engineered for versatility, supporting 3L, 4L, and A section belts. By utilizing a static-balanced design, the AK64 minimizes vibration, extending the service life of motor bearings and fan assemblies. The cast iron construction provides superior wear resistance compared to stamped steel alternatives, maintaining pitch diameter integrity under consistent load. Technicians frequently specify this A-section pulley for blower motors and exhaust fans where precise belt alignment and heat dissipation are critical. This component ensures reliable power transmission in belt-driven systems requiring a 7/8" bore interface.
Key Benefits
- Broad Belt Compatibility: Designed to work seamlessly with 3L, 4L, and A-style v-belts for maximum field flexibility.
- Durable Cast Iron Build: High-tensile strength material reduces the risk of rim distortion and groove wear.
- Machined Fixed Bore: Factory-set 7/8" bore with standard keyway ensures a secure, slip-free fit on the drive shaft.
- Vibration Reduction: Precision machining helps maintain system balance, reducing mechanical noise and stress.
Common Questions
What is the datum diameter for this sheave?
The Browning AK64X7/8 has a datum diameter of approximately 5.8" when used with A belts and 5.4" for 3L belts.
Can this pulley be used with a 5L or B belt?
No, this sheave is specifically grooved for 3L, 4L, and A belts. Using a 5L or B belt will result in improper seating and premature belt failure.
Does this sheave include the setscrew?
Yes, standard Browning AK sheaves come equipped with a standard setscrew over the keyway to secure the pulley to the motor or fan shaft.
