The S50MDD-248H99H99 is a double disk flexible coupling with a 1.0000 inch bore and 2.480 inch overall length, designed for high torque transmission and zero backlash. It features stainless steel pins and disks with aluminum alloy hubs and spacer, and compensates for angular misalignment up to 1.5° and axial motion up to ±0.02 inch. The coupling has a maximum torsional torque rating of 110.64 lbf·in, a maximum speed of 10,000 rpm, a moment of inertia of 11.481 oz·in², and lateral stiffness of 463.43 lbf·in/deg. It is secured with a 1/4-20 cap screw and has a static weight of 12.00 oz.
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.
