QD Bushings are designed with a split tapered flange, optimally positioned at the center of the flange and taper, providing superior clamping force ideal for sprockets, sheaves, and pulleys, surpassing standard bushings. Quick-disconnect bushings are indispensable for mounting V-belt drives, synchronous belt drives, and roller chain drives. The ingenious design allows for easy adjustment, gently expanding the split in the bushing wall to facilitate smooth sliding along the drive shaft. The flange securely mounts to the pulley or sprocket, ensuring pinpoint accuracy and enhanced positioning of the bushing compared to non-flanged counterparts.
The QD bushing is distinguished by its installation flexibility, offering two distinct mounting options: 'standard mount' or 'reverse mount'. Key to installation is the meticulous matching of the selected hole set and the firm seating of the bushing. As the bolts are progressively tightened, the QD bushing contracts to grip the shaft with unwavering security, ensuring dependable performance.
Mounting Instructions
1. Ensure all tapered cone surfaces of the bushing and the interior of the driven components are pristine and free from anti-seize lubricants for optimal performance.
2. Carefully slide the QD bushing onto the shaft, ensuring the flange end leads. Securely assemble the key for a stable setup.
3. Precisely position the QD bushing on the shaft. Secure the set screw over the key by hand-tightening with a standard wrench, avoiding any excessive force to prevent damage.
4. Align the large end of the sheave, pulley, or sprocket taper bore over the cone, ensuring drilled bolt holes are perfectly aligned with the tapered holes in the bushing flange for a seamless fit.
5. Systematically tighten the pull-up bolts, alternating and evenly, adhering to the torque specifications provided in the accompanying torque table for reliable fastening.
