In some cases it means that we actually develop and manufacture very special chain & sprocket types for 1 particular customer. In order to be able to do so, 3 things are important:M bushing with a 2-1/2″ bore is a high-quality, extremely durable, and high precision product that is manufactured out of solid steel. What really sets these M QD-type bushings apart is the extensive quality control procedure that is d1 to ensure you receive a consistent and premium product. M bushings are found in a wide range of applications and are most commonly used with sprockets, pulleys, sheaves, and more!

Standard Mounting1. Be sure that the tapered c1 surfaces on the bushing and the inside of the driven product is clean and free of oil or any anti-seize lubricants. 2. Slide the QD bushing on shaft, flange end first, then assemble key.3. Position the QD bushing on the shaft. Tighten the set screw over the key (hand tight) with a standard Allen wrench only. Do not use excessive force. 4. Slide the large end of sprocket or other part taper bore into position over the c1 aligning drilled bolt holes in the sprocket or other part with tapered holes into flange of bushing. Then assemble the pull-up bolts and lock washers.5. Tighten pull-up bolts alternatively and evenly to tightness indicated in the torque table below. Do not use extensions on the wrench handles. There should now be a gap between the face of the sprocket or other part hub and the flange of the QD bushing to insure a satisfactory c1 grip and press fit. Caution: this gap must not be closed. Dismounting1. Remove all pull-up bolts and screw them into tapped holes in sprocket or other part, against flange of QD bushing to break the c1 grip.2. Loosen set screw and slide QD bushing from shaft.Warnings: use of anti-seize lubricant on tapered c1 surfaces or on bolt threads when mounting may result in damage to sheaves and sprockets. This voids all manufacture’s warranties. Tel: +86-57188220973 Mail us: hzptcorp@gmail.com
