Disk couplings have no wearing parts

The series spans eight bore sizes ranging from 5 mm to 19 mm and are also availablea in comparable Imperial sizes. The couplings consist of two opposing disk halves with powerful 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 3 degrees or parallel misalignment of up to 7mm and still transmit nearly full rotational torque. These 416 Stainless steel couplings incorporate an NdFeB, nickel plated magnet. The hub sections are offered singularly and are offered with or without a keyway and are fastened to shafts with a set screw. The coupling outside diameter ranges from 43.7 mm to 73 mm. Sterling Instruments expects the couplings to find applications in the material handling area such as for conveyor belts and film transport. Machinery for capping of syringes or bottles, shrink wrapping, constant wire tension coil winding and film tensioning are other likely uses.
