Sterling Instrument's magnetic disk couplings feature no friction or wearing parts

Sterling Instrument unveils a series of magnetic disk couplings that features no friction or wearing parts, uses no electricity and no magnetic particles to leak. The units, identified as the S50DCM (inch) and S50DCMM (metric) Series, are stocked in eight different bore sizes ranging from .1875 inches to 1.000 inches (5 mm to 19 mm). The couplings consist of two opposing disk halves with rare earth magnets. The torque applied to one disk is transferred through an air gap to the other disk. Because of its simple flat design, one can have angular misalignment of up to 3O or parallel misalignment of up to 1/4 inch and still transmit nearly full rotational torque.

These 416 Stainless steel couplings incorporate an NdFeB, nickel plated magnet. The hub sections are offered singularly, with or without a keyway and are fastened to shafts with an included set screw. The coupling O.D. ranges from 1.72 inches to 2.86 inches (43.7 mm to 73 mm).
