The S50MSKMS63K20K20 is a miniature slit-type flexible coupling with 20 mm bores on both sides, designed to transmit torque with zero backlash and high torsional stiffness. It is made of stainless steel, compensates for up to 2° angular offset and ±0.5 mm axial offset, and has a maximum torque rating of 35 N·m at 10,000 rpm. The coupling has a total length of 90 mm, a mass of 1300 grams, and a torsional stiffness of 1800 N·m/rad. It is secured with an M8 set screw and conforms to ISO conventions for keyway projections.
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.
