Martin CQW18026X40 Quarry Duty Wing Pulley, 4 in Dia Shaft, 18 in OD, 26 in W Face, Steel

Martin's quarry duty wing pulleys are constructed from extremely heavy materials and are recognized in the industry as the most aggressive wing pulley in the business. All Martin wing pulleys utilize the unique 'end-pipe' design, which offers ultimate protection against wing folding and hub-weld fatigue. Our minimum 3/4 in thick contact bar yields additional life in abrasive applications where our competitors thinner bar does not. Additionally, our 3/8 in thick wing and 5/16 in gussets offer higher structural support in aggressive applications. All Martin quarry duty wing pulleys utilize full depth keyed bushings which offer maximum clamping force on the shaft and minimize ''pulley walking''. The quarry duty wing pulley has changed the industry and has spawned many 'knock-offs', but none have been able to reproduce the original. For the most aggressive applications, specify the best, specify the Martin quarry duty wing pulley.
