Browning SK 1 5/8 Bushing
The Browning SK 1 5/8 Bushing is a heavy-duty, ductile iron power transmission component designed for high-torque HVACR and industrial drive applications. As part of the SK Series Q-D Bushing line, this unit features a 1 5/8" bore with a standard 3/8" x 3/16" keyseat, ensuring a precise fit for 1.625-inch shafts. Engineered for versatility, it supports conventional or reverse mounting, allowing the flange to be positioned toward or away from the motor to accommodate tight clearances. With a robust torque capacity of 7,000 in-lbs and a 3/4" per foot self-locking taper, it provides superior mechanical locking that prevents shaft slippage under heavy loads. The assembly utilizes three 5/16-18 x 2" cap screws on a 3.3125" bolt circle, requiring a wrench torque of 15 ft-lbs for secure seating. This Quick-Disconnect bushing is essential for contractors maintaining blowers, fans, and pump systems where minimal downtime and reliable alignment are critical.
Key Benefits- High Torque Transfer: Rated for up to 7,000 in-lbs, making it ideal for high-demand HVAC fan and blower drives.
- Flexible Installation: Features reverse mounting capability to ensure a flush fit in restricted machine housings.
- Self-Locking Taper: The 3/4" per foot taper design provides a true interference fit, reducing vibrational wear on shafts.
- Durable Construction: Manufactured from ASTM 65-45-12 ductile iron for enhanced tensile strength and fatigue resistance compared to standard grey iron.
- Standardized Compatibility: Fits any SK series sprocket, sheave, or pulley, streamlining inventory for service technicians.
What is the correct torque for the Browning SK 1 5/8 cap screws?
The three 5/16-18 x 2" cap screws should be tightened to 15 ft-lbs (180 in-lbs) using a torque wrench to ensure even seating without over-stressing the flange.
Does this bushing require a special key?
The SK 1 5/8 utilizes a standard 3/8" x 3/16" keyway. Always ensure the key runs the full length of the 1.75" bore to maintain proper load distribution.
Can I use this on a 1.625-inch shaft from another manufacturer?
Yes, as long as the shaft diameter is 1 5/8" and the mating component (sheave or sprocket) is bored for an SK series Q-D bushing, this part is interchangeable with other QD-style hardware.
