The S50GS2MA25H0810 is an antivibration flexible coupling designed to reduce hunting in high-gain servo systems by absorbing vibration while maintaining torsional rigidity. It features aluminum hubs and a molded rubber (FKM) center with steel cap screws, and compensates for up to 1.5° angular offset, 0.2 mm lateral offset, and ±0.3 mm axial motion. The coupling operates from -10°C to +120°C and is rated for 2.3 N·m torque at 25,000 rpm with a torsional stiffness of 290 N·m/rad and a polar moment of inertia of 2.4 × 10⁻⁶ kg·m². The shaft bores are 8 mm and 10 mm with h7 tolerance (0/-0.015 mm), and the overall length is 27 mm. The coupling weighs 24 grams based on maximum bore dimensions.
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.
