Luff can custom design and engineer pulleys to meet your specific needs and are available in drum, wing, spiral wrapped and helical designs. Luff’s team can assist with all aspects of pulley design by using state-of-the-art finite element analysis (FEA) software. All Luff Pulleys are backed by a full two-year warranty — providing years of valuable, maintenance-free service.
Luff utilizes a trapezoidal machined crown to ensure maximum concentricity and improved belt tracking. Having concentricity of 0.0000 – 0.030”, compared to the industry standard of 0.080 – 0.125”, provides constant contact with the belt. This results in consistent discharge, less shaft deflection and reduced stress on the bearings.
