This EPG power transmission products are designed to deliver both reliable performance and cost-efficiency. Every product is utility-tested and engineered to meet stringent standards for uniformity in dimension, heat treatment, tensile strength and other critical characteristics. As a cost-effective alternative designed specifically for general-duty use, EPG’s expanding line of products are available in all frequently ordered sizes and specifications, including ball bearings, mounted units, roller chain, seals, gauges, sheaves and more.Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, pto shaft, agricultural gearboxes,torque limiters, shaft collars, motor bases and motor slides, chain & sprocket detachers, chain & sprocket guides, universal joint, rod ends and yokes. 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.3TB70 Pulley uses a Q1 series bushing, is directly interchangeable with other manufacturers, is 7.35″ in diameter, and is manufactured in accordance with ARPM Standard for safe operation. With B-series TB pulleys you can use A, 4L, B, 5L, AX, BX, AA, and BB belts. What separates this 3 groove 3TB70 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 3TB70 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, Q1 bushings, shafting, key-stock, motors, gearboxes, bearings, and much more!
