Zero-maintenance bearings from Zero-Max are available as an option for Schmidt offset couplings, eliminating the need for periodic coupling lubrication and the resulting system downtime. Schmidt offset couplings provide precision for parallel offset shafts. They transmit constant angular velocity and torque in a wide range of parallel shaft misalignments. Used in a wide range of machine applications such as automated assembly systems, the Schmidt sealed bearing coupling feature incorporates needle bearings with internal micro-poly lubrication. Compact in design, it keeps out contaminants and foreign matter, enabling the couplings to be used in less than ideal operating environments. Schmidt offset couplings are designed to handle parallel offset up to 17 in (432 mm) and are available with torque capacities up to 459,000 lb·in (52000 N·m). They impose no side loads on shafts or bearings.
