Browning 2AK74H Sheave
The Browning 2AK74H Sheave is a precision-engineered 7.25" outside diameter drive component designed for dual-groove power transmission systems. Manufactured from high-grade ASTM A48 Class 30 gray cast iron, this double groove sheave provides the structural rigidity required to manage belt tension and minimize vibration in demanding HVACR blower and motor applications. Engineered for maximum versatility, it is compatible with 3L, 4L, and A section v-belts, allowing technicians to maintain or adjust drive ratios with localized reliability. The hub is designed for use with H series split tapered bushings, ensuring a secure, concentric fit on the shaft that prevents keyway wallow and simplifies removal during maintenance. By utilizing a cast iron V-belt pulley configuration, this component offers superior heat dissipation and wear resistance compared to light-duty alternatives, making it a staple for commercial air handling units and industrial fan drives requiring consistent RPM stability.
Key Benefits
- High-Grade Construction: Built from durable cast iron for long-term resistance to abrasive wear and thermal stress.
- H-Bushing Compatibility: Utilizes the H series bushing system for easy installation and precise shaft alignment.
- Dual-Groove Design: Supports two groove AK sheave configurations to increase torque capacity and provide redundancy.
- Multi-Belt Versatility: Machined to accept 3L, 4L, and A belts, streamlining inventory for various light-duty drives.
- Static Balance: Precision-machined to reduce radial vibration and extend the service life of motor bearings.
Common Questions
What is the effective pitch diameter for A-section belts?
On the Browning 2AK74H, the datum diameter for A belts is 7.20", and for 4L belts, it is 7.00", which should be used for all drive ratio calculations.
Can I use this sheave with a B-section belt?
No, this sheave is specifically grooved for A belts (4L) and 3L belts. Using a B-section belt will result in improper seating and premature belt failure.
Does this sheave come with the bore bushing?
This is the sheave only. It must be paired with an H split tapered bushing sized to your specific motor or fan shaft diameter.
