The S50MHSM40H10H14 is a heavy-duty single disk flexible coupling for high-torque, zero-backlash transmission between shafts, with anodized aluminum hubs and stainless steel pins and disks. It accommodates a maximum angular offset of 1° and axial motion of ±0.2 mm. The coupling has bore diameters of 10 mm and 14 mm, a 40 mm outer diameter, 38 mm length, 16.5 mm hub thickness, 12 mm bore keyway width, and uses a 14 mm screw. Rated for a maximum torque of 4 N·m and 15000 rpm, it exhibits a torsional stiffness of 2800 N·m/rad and a static moment of inertia of 1.2 x 10⁻⁵ kg·m², weighing 66 grams. All values are based on specifications for the S50MHSM40 series, as the exact part number is not independently listed but falls within its known variants.
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.
