Browning SDS 1 1/8 Bushing

The Browning SDS 1 1/8 Bushing is a high-performance Quick Disconnect (Q-D) bushing engineered for precise shaft mounting in industrial HVACR and power transmission systems. Manufactured from high-strength ductile iron, this SDS Series bushing features a 1 1/8" finished bore and a standard 1/4" x 1/8" keyseat, ensuring a secure and reliable mechanical connection. Designed with a functional 3/4" per foot self-locking taper, it provides a superior clamping force that minimizes vibration and prevents shaft slippage under high-torque conditions. The split-barrel design allows for easy installation and removal, while the reverse mounting capability provides essential flexibility for technicians working with varied sheave or sprocket configurations. Rated for a torque capacity of 5,000 in-lb, this industry-standard QD bushing is fully interchangeable with competitive models, making it a versatile choice for maintaining or upgrading belt-driven equipment and fan assemblies in the field.

Key Benefits:

• Ductile Iron Construction: High-tensile material provides exceptional durability and resistance to cracking during high-torque applications.
• Self-Locking Taper: The 3/4" per foot taper ensures a 100% mechanical lock between the shaft and the hub, reducing maintenance intervals.
• Reverse Mounting Capability: Allows for mounting from either side of the flange to accommodate tight spaces or specific alignment needs.
• Universal Compatibility: Designed to fit perfectly with Browning pulleys, sheaves, and sprockets, and is interchangeable with other Q-D style systems.
• Precision Keyway: Features a standard 1/4" x 1/8" keyseat to provide positive drive and high torque transmission without relying solely on friction.

Common Questions:

• What is the proper installation torque for the SDS 1 1/8 bushing? The terminal wrench torque for the 1/4-20 cap screws used on this bushing should be approximately 9 ft-lbs (108 in-lbs) to ensure a secure, seated fit.
• Can this bushing be used on a worn shaft? While the split-barrel design provides a degree of clamping adjustment, it is recommended to use it on shafts within standard tolerances to maintain concentricity and avoid failure.
• Is a gap required between the bushing flange and the hub? Yes, a gap of approximately 1/8" to 1/4" should remain between the flange and the hub face after tightening to ensure the taper has fully seated and locked.
