The S50MDS-126H37H37 is a zero backlash, split hub, single disk flexible coupling designed for torque transmission with misalignment compensation. It has a 0.3750 inch bore, 1.142 inch overall length, and 1.260 inch outer diameter. The coupling accommodates a maximum angular offset of 0.7° and axial motion of ±0.008 inch, with no lateral offset capability. It is constructed with stainless steel pins and disks and aluminum alloy hubs and spacer. The coupling has a static torque rating of 22.13 lbf·in, a maximum speed of 6000 rpm, a torsional stiffness of 247.20 lbf·in/deg, a moment of inertia of 0.394 oz·in², and a weight of 1.45 oz. The shaft tolerance for the 0.3750 inch bore is +0.0000/-0.0006 inch.
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.
