The S50MDS-074H25H25 is a slit type single disk flexible coupling with a bore diameter of 0.25 inches and an overall length of 0.787 inches. It features zero backlash, ensuring precise torque transmission without play. The coupling is constructed from stainless steel for the pins and disks, while the hubs and spacer are made from aluminum alloy, providing a lightweight yet durable design. This coupling accommodates a maximum angular offset of 0.7 degrees and allows for axial motion of ±0.008 inches, making it suitable for applications requiring misalignment compensation. It is maintenance-free, which can reduce downtime and maintenance costs. The coupling is designed to handle a maximum torque of 6.20 lbf-in and can operate at speeds up to 10,000 RPM. Its static torsional stiffness is rated at 43.26 lbf-in/deg, contributing to its high performance in demanding applications.
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.
