The S50DCMM60H12 is a magnetic disk coupling with a 12 mm bore, composed of 416 stainless steel hubs and nickel-plated NdFeB magnets. It accommodates a maximum angular offset of 3° and a maximum parallel offset of 6.35 mm, with a maximum operating temperature of +140°C. The coupling has an outer diameter of 60 mm, an overall length of 38 mm, and an air gap of 9 mm. It is rated for a breakaway torque of 1 N·m, a maximum torque of 1.4 N·m, and supports up to 19,000 rpm with a weight of 0.55 kg per hub half. The hub includes a keyway with a width of 4 mm and a height of 13.8 mm, per ISO convention. The part is priced per hub half and requires pairing with an identical hub 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.
