Below is a sample of some of the more common specialty pulleys Martin can manufacture. • Available in Wide Variety of MTO Sizes • Meet or Exceed CEMA Standards • Superior Strength • Pulleys for Any Industry • Fast Reliable Service DSP Dead Shaft Pulleys The Martin Dead Shaft Pulley (DSP) is designed to withstand the most rugged applications in any harsh environment. The DSP has been used in the industry to help reduce damage to conventional externally mounted pillow block bearings. The DSP features an internal bearing, tucked back close to the pulley where falling material is less likely to damage the bearings and seals. The Martin DSP features an off-the-shelf piloted flange cartridge (interchangeable with multiple bearing manufacturers) suited with harsh environment seals and external end caps for maximum protection against material contamination. Each Martin DSP Pulley is shipped with an aggressively constructed pedestal which is fabricated to drop into the same dimensional footprint of the pillow block which it is replacing (this must be specified at the time of order). The DSP is available as either wing or drum pulleys. DSP Wing Pulley with Martin Pedestals
