This The high precise CNC equipment, such as Slow-feeding wire-cut machine, jig grinding machine and electric discharge machine, ensures the top quality precision of mould processing, with the high efficient and environmental protection acid rolling line being the largest raw material converting equipment in the field in china; The wildly use of automatic milling machine, high-speed automatic feeding punch, high speed automatic rolling and assembling machine guarantees the high quality and efficiency of comp1nts and chain & sprocket making. Firstly: innovative product engineering. We are continuously improving well-proven and established products in the areas of drive and conveyance technology or are looking for possible innovations. One example for this is the maintenance-free chain & sprocket. Secondly: excellent production engineering. Our production processes are also constantly improved upon. Quite frequently effective, new products are only possible because of innovative production methods. Thirdly: competent application consulting.BK57 Pulley 1-1/8″ bore is directly interchangeable with other manufacturers, is 5.45″ in diameter, and is manufactured in accordance with ARPM Standard IP20 for safe operation. It works with belt sizes A, 4L, B, 5L, AX, BX, AA, and BB. What separates this BK57 pulley from the others is that it is made using a high grade-35 cast iron, is phosphate coated, painted, and balanced at the factory. Using the grade 35 cast iron offers a higher10sile strength and is more wear resistant than the more commonly used grade 25. While the phosphate coated and then painted finish adds corrosion resistance to the BK57 pulley. Then, because this pulley is dynamically balanced it runs smoother which gives bearings and other comp1nts of the equipment a longer working life. Additionally, we stock a full line of premium A, 4L, B, 5L, AX, BX, AA, and BB belts, shafting, key-stock, motors, gearboxes, bearings, and much more!
