The S50MHSM63H18H18 is a heavy-duty single disk flexible coupling designed for high torque and high torsional stiffness applications with zero backlash. It features stainless steel pins and disks with anodized aluminum hubs, compensates for up to 1° angular offset and ±0.2 mm axial motion, and uses a clamp screw design. It has a bore diameter of 18 mm on both ends, an overall length of 50 mm, a maximum outer diameter of 63 mm, and is secured with M6 screws. It is rated for a maximum torque of 10 N·m, a maximum speed of 10,000 rpm, a torsional stiffness of 5000 N·m/rad, and a rotational inertia of 8.4 × 10⁻⁵ kg·m², with a mass of 190 grams.
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.
