The S50DCMM73 is a magnetic disk coupling consisting of two hub halves with 416 stainless steel hubs and NdFeB magnets nickel plated, designed to transmit torque while compensating for angular misalignment up to 3° and parallel offset up to 6.35 mm. The coupling has a maximum operating temperature of +140°C and an overall length of 55.6 mm. It is rated for a breakaway torque of 1.7 N·m and a maximum torque of 2.3 N·m, with a maximum speed of 16000 rpm and a weight of 1.13 kg per coupling. The hub bore is not specified for this exact part number, as it is listed without a bore suffix, indicating a solid hub half with no bore and no keyway. The part is priced per hub half and requires pairing with another matching hub half to form a complete coupling.
Couplings Types
Couplings can be divided into two categories: flexible and rigid. Both types are used to connect two rotating shafts driven by a motor and transmit torque and angular velocity; however, flexible couplings and shafts are designed to accommodate angular misalignment, angular offset, axial movement, and a variety of load conditions. A flexible coupling is pliable due to the twisting and compression of a durable, adaptable material, like neoprene, rubber, or silicone.
Flexibility can also be achieved with thin metal disks, corrugated aluminum bellows (bellows couplings), or even a stainless-steel ball (miniature ball couplings). Some materials can provide vibration reduction, as in our precision flexible antivibration couplings.
Rigid couplings are limited by comparison; rigid couplings are used when shafts are already positioned in precise lateral and angular alignment. Their rigid design inhibits shaft misalignment. They can generally transmit more power than flexible couplings due to their rigidity.
Even the most complicated application challenges can be solved by our skilled engineers, they will identify the best coupling solution for your application. SDP/SI provides a comprehensive range of rigid and flexible couplings. Many of our precision couplings, including the Miniature Bellows Coupling and the Neo-Flex Coupling, have our patented Fairloc® Hub design, which solves phasing, timing, positioning, and frequent removal problems.
