Powerhouse™ MX pulleys are built for high torque, low speed applications. They outperform the industry standards and are never made from sintered metal. Sintered metal pulleys are prone to cracking, fracturing, and are harder to machine. Residual porosity lowers a sintered metal pulley's final mechanical and physical properties. Powerhouse™ MX pulleys are not made from gray iron until they reach 9 in outside diameter instead of the 4 in outside diameter of our competitors' pulleys. Gray iron has a much lower tensile strength and makes a poor shock resistor when compared to ductile iron. Gray iron is also too brittle for some applications. B&B Manufacturing now offers Powerhouse™ MX pulleys with finished bores from stock. Finished bore pulleys eliminate the need for extra hardware such as the bushing. Because there are fewer parts, the Powerhouse™ MX pulleys with finished bores are easier to assemble and cheaper than the sum of the bushings and the bushed timing pulleys.
