3TB124 Sheave three-groove 12.75" OD

This 3TB124 Pulley uses a Q1 series bushing, is directly interchangeable with other manufacturers, is 12.75" 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 three groove 3TB124 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 higher tensile 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 3TB124 pulley. Then, because this pulley is dynamically balanced it runs smoother which gives bearings and other components 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!
