QD Bushings are designed with a split tapered flange, strategically split at the center for optimal performance. Perfect for use with sprockets, sheaves, and pulleys, they deliver exceptional clamping force, surpassing standard bored-to-size bushings. Ideal for mounting V-belt drives, synchronous belt drives, and roller chain drives, these bushings are easy to adjust with a gentle increase in the bushing wall split, allowing seamless sliding along the drive shaft. The flange's precise mounting to the pulley or sprocket ensures superior positioning within the bore, outclassing non-flanged alternatives.
The innovative QD bushing offers unparalleled installation flexibility, presenting two distinctive mounting options: 'standard mount' or 'reverse mount'. A critical factor in installation is the precise alignment of the selected hole set, ensuring the bushing is firmly seated. As the bolts are evenly tightened, the QD bushing contracts, securing a robust grip on the shaft.
Mounting Guidelines
1. Ensure the tapered cone surfaces of both the bushing and driven components are spotlessly clean and free from anti-seize lubricants.
2. Slide the QD bushing onto the shaft with the flange end leading the way. Insert the key for secure assembly.
3. Position the QD bushing on the shaft precisely. Tighten the set screw over the key to 'hand tight' with a standard wrench, avoiding excessive force.
4. Align the large end of the sheave, pulley, or sprocket taper bore over the cone, matching drilled bolt holes in the component with tapered holes in the bushing flange.
5. Alternately and evenly tighten the pull-up bolts to the specified torque as indicated in the torque table on the reverse side.
