This 3TB70 pulley uses one Q1 series socket, is directly interchangeable with other manufacturers, has a diameter of 7.35 inches and is manufactured to the ARPM standard for safe operation. With B series TB pulleys you can A-, 4L-, b-, 5L-, AX, BX-, AA- and BB strap use. What sets this 3TB70 three groove pulley apart from the others is that it is manufactured from a high quality 35 cast iron, phosphated, painted and factory balanced. Using Grade 35 cast iron provides higher tensile strength and is more wear resistant than the more commonly used Grade 25. While the phosphated and then painted surface gives the 3TB70 pulley corrosion resistance. Because this pulley is dynamically balanced, it runs more smoothly, giving bearings and other equipment components longer life. We also carry a complete range to Premium A-, 4L-, B-, 5L-, AX, BX-, AA- and BB strap, Q1 sockets, Waves, Key stick, engines, gearboxes, bearings and much more!
