Description
The AMEC SDS type QD (Quick Detachable) style bushing is a high-performance, flanged mechanical component used to securely lock sheaves, pulleys, and sprockets onto a drive shaft. It features a standard tapered barrel with a single split, providing a robust, 360-degree clamping grip that prevents component slippage under heavy industrial loads.
Key Features
- Built-in Keyway: Unlike smaller series at maximum capacity, the SDS series maintains enough wall thickness to accommodate a standard mechanical keyway across all popular sizes, preventing shaft rotation under high torque.
- Flanged Construction: Features an integrated collar with pre-drilled holes for standard mounting bolts and threaded holes for easy removal.
- Jackscrew Removal: Utilizes pull-up bolts as jackscrews for fast, hassle-free removal, drastically reducing machinery maintenance downtime.
- Premium Materials: Precision-machined from high-grade cast iron or steel with a corrosion-resistant finish to withstand harsh environments.
Technical Specifications
- Barrel Taper: 3/4 inch per foot
- Bolt Circle Diameter: 2.688 inches
- Mounting Hardware: Requires three 1/4"-20 cap screws
- Bore Range: Available in exact fractional sizes from 1/2" up to 2"
Common Applications
- Industrial V-belt drives and high-torque synchronous pulleys
- Heavy-duty roller chain sprockets
- Conveyor system drive rollers
- Air handling fans and industrial blowers
