Browning SH 1 1/8 Bushing

The Browning SH 1 1/8 Bushing is a high-performance Quick-Disconnect (QD) bushing designed for precise shaft mounting in industrial drive systems. Engineered from high-strength ductile iron (Grade 65-45-15), this SH series component features a 1-1/8" finished bore with a standard 1/4" x 1/8" keyseat. The split-taper design provides a 3/4" per foot taper, ensuring a reliable, self-locking mechanical grip that effectively minimizes vibration and prevents shaft slippage under heavy loads. With a rated torque capacity of 3,500 in-lb, it is ideal for securing Browning sheaves, sprockets, and pulleys in HVACR and power transmission applications. This bushing supports both conventional and reverse mounting, allowing for maximum installation flexibility in tight mechanical spaces. The three 1/4-20 x 1-3/8" cap screws facilitate easy installation and removal, acting as jack screws during disassembly to break the cone grip without damaging the drive components or the shaft.

• Ductile Iron Construction: Enhanced material strength over standard cast iron for superior durability in high-torque environments.
• Self-Locking Taper: The 3/4" per foot barrel taper ensures concentric alignment and a secure 360-degree clamp fit.
• Versatile Mounting: Supports reverse mounting for flush-face applications or restricted space configurations.
• Interchangeable Design: Fully compatible with major industry-standard QD sheaves and sprockets.
• Ease of Maintenance: Integrated pull-up and jack screw holes simplify component swaps, reducing system downtime.

• Does this bushing require lubrication during installation? No, the tapered surfaces and bore must be clean and dry. Applying lubricants can lead to over-tightening and potential hub fracture.
• What is the recommended bolt torque for the SH series? The 1/4" cap screws should be tightened to approximately 9 ft-lbs (108 in-lbs) for optimal seating.
• Can I use this with a different brand sheave? Yes, the Browning SH series is a standard QD design and is interchangeable with other manufacturers' QD-style hubs.
