The S50DCMM60H18 is a magnetic disk coupling hub half with an 18 mm bore, made of 416 stainless steel and paired with a neodymium iron boron magnet nickel plated for corrosion resistance. It is designed to be combined with an identical hub half to form a complete coupling, compensating for up to 3° angular offset and 6.35 mm parallel misalignment, with a maximum operating temperature of +140°C. The coupling transmits a breakaway torque of 1 N·m and a maximum torque of 1.4 N·m, supporting up to 0.25 hp at 19,000 rpm. The overall length is 38 mm, and the set screw is M5. The keyway dimensions are width 6 mm and height 20.8 mm, per ISO convention.
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.
