Zero Maintenance Bearings Available for Schmidt Offset Couplings
October 4, 2010—Zero maintenance bearings are now available as an option for Schmidt Offset couplings from Zero-Max. This new coupling feature eliminates the need for periodic coupling lubrication and the resulting downtime. These couplings provide precision for parallel offset shafts. They transmit constant angular velocity and torque in a wide range of parallel shaft misalignments. They are designed for a wide range of machine applications including printing, embossing, paper converting, pharmaceutical and automated assembly systems. The new sealed bearing feature incorporates needle bearings with internal micro-poly lubrication. There are no lube fittings, making for a cleaner coupling setup. Compact in design, the couplings keep out contaminants and foreign matter, enabling the couplings to be used in less than ideal operating environments. The Schmidt Offset couplings are designed to handle parallel offset up to 17 in. and are available with torque capacities up to 459,000 in-lbs. They impose no side loads on shafts or bearings to eliminate radial shaft vibrations.
