Timing Belt Pulley - Custom

Click to Enlarge

Custom synchronous belt pulleys allow the end user to design a custom timing belt pulley to match their specific needs. This eliminates the frustrations often caused by trying to modify a off the shelf timing belt gear pulley. Additional custom synchronous belt pulley design resources have been made available by Pfeifer Industries within the following sections custom timing belt pulley design form and timing belt pulley design features. Pfeifer Industries specializes in producing sub-minimal tooth count timing belt pulleys. We are able to produce 8mm pitch pulleys down to 14 teeth. We also take pride in being able to maximize weight reduction in the timing belt gear pulleys we produce thanks to our vast knowledge of the demands required by the various racing applications that we support with our products.
