Martin Elite Series® drum pulleys feature true-turbine profile end plates that distribute stress more evenly, unlike competitors dual tapered radius end plates, resulting in reduced stress in the hub region and the reduced likelihood of end disc failure. Once the pulley is formed, Martin utilizes a submerged arc weldment, versus competitors mig weldment, to ensure optimum connection of its individual components and incorporates a machined weld operation into the end plate to achieve maximum weld penetration and flexibility. Our trademark Elite Series® pulley is truly optimized for XT bushings and keyless locking devices.
