Browning SK 1 7/8 Bushing
The Browning SK 1 7/8 Bushing is a heavy-duty Quick-Disconnect (Q-D) bushing engineered for high-torque power transmission in industrial HVACR systems. Built from high-strength ductile iron, this component features a 1-7/8" precision-machined bore and a 1/2" x 1/4" standard keyseat, ensuring a secure, slip-free interface between shafts and drive components. The design utilizes a 3/4" per foot taper to provide a robust mechanical lock that effectively handles 7,000 in-lb torque capacity, making it ideal for large-scale fan drives, compressors, and motor assemblies.
Designed for professional contractors, this split taper bushing supports conventional and reverse mounting, allowing for versatile installation in tight mechanical rooms or flush-mount pulley configurations. The use of three 5/16-18 x 2" cap screws on a 3.3125" bolt circle simplifies the mounting of Browning sheaves and sprockets without requiring specialized pullers. Its standard keyway design prevents shaft marring and high-speed vibration, maintaining drive alignment and operational efficiency across high-horsepower applications.
Key Benefits for Technicians:
- Broad Compatibility: Seamlessly integrates with SK Series sheaves, pulleys, and sprockets commonly found in commercial HVAC equipment.
- Dual-Mount Versatility: Supports flange-in or flange-out orientation for precise alignment in complex drive trains.
- Self-Locking Taper: The 3/4" per foot taper ensures a concentrated grip, significantly reducing the risk of component slippage under heavy loads.
- Durable Ductile Iron: Provides superior tensile strength and fatigue resistance compared to standard gray iron alternatives.
- Interchangeable Design: Serves as a direct industry-standard interchange for other SK series QD bushings, simplifying inventory management.
Common Technical Questions:
What is the maximum torque rating for the Browning SK 1 7/8?
This bushing is rated for a capacity of 7,000 inch-pounds, making it suitable for high-demand industrial motor drives.
Does this bushing require a specific bolt size for installation?
Yes, it requires three 5/16-18 x 2" cap screws. Always use high-grade fasteners to ensure the 15 ft-lb wrench torque specification is met.
Can I use this on a shaft without a keyway?
While the taper provides a strong grip, the 1/2" x 1/4" keyseat is critical for transmitting full rated torque and ensuring the safety of the drive assembly.
