The S50MSX-114H37H37 is a split hub flexible coupling with a 0.375 in. bore and 1.181 in. overall length, designed to transmit torque while accommodating angular misalignment up to 5°, lateral offset up to 0.002 in., and axial motion of ±0.004 in. It is constructed from aluminum alloy ASTM 7075, features zero backlash, and is maintenance-free. The coupling has a maximum torsional torque rating of 17.70 lbf in, a static torsional stiffness of 216.27 lbf in/deg, and a rated speed of 21000 rpm. Its moment of inertia is 1.45 oz. in², and it uses a #6-32 cap screw for securing the hub.
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.
