The S50MDS-196H75H75 is a single-disk flexible coupling with a 0.7500 inch bore, designed for zero backlash and high torsional stiffness in precision applications. It has an overall length of 1.654 inches and an outside diameter of 1.969 inches. The coupling compensates for a maximum angular offset of 0.7° and axial motion of ±0.008 inch, with no lateral offset capability. Constructed with stainless steel pins and disks and aluminum alloy hubs, it supports a maximum static torque of 79.66 lbf·in and a maximum rotational speed of 4000 rpm. Its torsional stiffness is 478.95 lbf·in/deg, and it weighs 4.94 ounces. The recommended shaft tolerance for this bore size is +0.0000/-0.0008 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.
