A roller chain & sprocket strand can be shortened by removing links and lengthened by adding whole or a half links (offset links).4B74SK sheave features 4 grooves, is 7.75″ in diameter, and is designed to use a SK bushing. QD (quick detachable) style sheaves offer a wider selection of bore sizes versus a standard “fixed” bore style sheave. Also because they are a 2-comp1nt part if 1 comp1nt fails the entire part doesn’t need to be replaced. All of our sheaves are manufactured out of an extremely durable cast iron, are dynamically balanced at the factory, and are phosphated then painted for corrosion resistance. Additionally, we stock a full line of premium A, 4L, B, 5L, AX, BX, AA, and BB belts, SK bushings, shafting, key-stock, motors, gearboxes, bearings, and much more!
