This Manufacturer of standard and custom roller chains. Suitable for aging, stress relieving, heat treating and powder coating applications. Aerospace, automotive, military, energy, composite, pharmaceutical and various other industries served. Turnkey systems integration and most items available in stock.The new products include a series of high-tech and high quality chain & sprockets and sprockets and gears, such as chain & sprockets and gearboxes for agricultural machineries, metallurgical chain & sprockets, escalator step-chain & sprockets, high-speed tooth chain & sprockets, timing chain & sprockets, self-lubrication chain & sprockets, among which have type high speed tooth chain & sprocket for car branch dynamic box and aerial chain & sprockets fill in the blanks of chain & sprocket in China. Standard single-strand roller chain & sprocket, standardized by ASME, is an assembly of alternating pin links and roller links. The distance between pin centers is called the pitch. The pitch is what categorizes the size of the chain & sprocket. The larger the pitch, the higher the load rating. Chain & Sprockets with small pitches carry smaller loads, operate more quietly, and at higher speeds. Multi-strand, small-pitch roller chain & sprockets are a good solution for high-load, high-speed applications.SH QD type bushing is a high-strength premium quality bushing with a 42 millimeter bore. What sets this bushing apart from others is the high-quality steel construction, and strict quality control procedure to ensure that you are getting a product that is consistent and precise. ept Roller Chain & Sprocket and sprockets is a 1-stop shop industrial power transmission supply facility that is focused on quality, value, and great customer service. We also have a highly-trained expert staff to answer any questions that you might have.

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: [email protected]
