Zero-Maintenance Bearings Reduce Coupling Concerns

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 connections for parallel offset shafts, and are able to transmit constant angular velocity and torque in a wide range of parallel shaft misalignments. Schmidt couplings 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. This means that there are no lube fittings anywhere in the coupling, making for a cleaner installation.

The Schmidt couplings are very compact and keep out contaminants and foreign debris, allowing them to be used in less than ideal environments. These couplings are able to handle parallel shaft offsets up to 17 inches, and are available in torque capacities up to 459,000 in-lbs (38,250 ft-lbs). They also impose no side loads on shafts or bearings, thus eliminating radial shaft vibrations.
