The S50GL2MA19H0608 is a long-series antivibration flexible coupling designed for high-response servo systems, featuring aluminum hubs and a molded rubber (FKM) center to absorb vibration while maintaining torsional rigidity. It accommodates shafts with 6 mm and 8 mm bores and has an overall length of 34 mm. The coupling supports a maximum angular offset of 1.5°, axial motion of ±0.2 mm, and lateral offset of 1.5 mm. It operates from -10°C to +120°C and has a rated torque of 2.1 N·m at 33,000 rpm, with rotational inertia of 1.0 × 10⁻⁶ kg·m² and torsional stiffness of 210 N·m/rad. All variants share these performance characteristics and material composition.
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.
