Description

QD bushings are high-engineering tapered locking bushings, designed to quickly and securely mount pulleys, sprockets, and couplings to shafts. Their flange-based bolt tightening system ensures a robust connection and simple disassembly, optimizing maintenance times.

Manufactured from high-quality steel or cast iron, QD bushings provide a powerful and precise interference fit, eliminating the need for complex machining on shafts.

Key features of QD bushings

  • Quick Installation and Removal : The "Quick Disconnect" system allows for swift installation. For removal, the same bolts act as jackscrews, releasing the part effortlessly and without special tools.
  • Firm and Precise Fit : The tapered design ensures a 360° grip on the shaft, achieving excellent concentricity. This reduces vibration, prevents wear, and guarantees smooth power transmission.
  • High Torque Transmission Capacity: Their design allows them to transmit higher torque values than traditional keyed systems, offering a more reliable connection in high-load applications.
  • Flexibility and Standardization: A single component (pulley or sprocket) can be mounted on shafts of different diameters simply by changing the QD bushing. This simplifies inventory management and reduces costs.
  • Versatile Installation: The bushing can be mounted in a standard or reverse configuration to adapt to machinery space constraints, without sacrificing clamping strength.
