The S50GT2MA15H0404 is a compact antivibration flexible coupling designed for high-torque, high-response servo systems, featuring aluminum hubs and a molded FKM rubber center that absorbs vibration while maintaining torsional rigidity. It has bore diameters of 4 mm on both ends and an overall length of 23 mm. The coupling accommodates a maximum angular offset of 1.5°, a lateral offset of 0.15 mm, and axial motion of ±0.2 mm, with an operating temperature range of -10°C to +120°C. It is rated for a maximum torque of 1.1 N·m, a maximum speed of 42,000 rpm, and has a torsional stiffness of 110 N·m/rad and a rotational inertia of 2.6 × 10⁻⁷ kg·m². Weight is 9 grams based on the maximum bore size. The shaft tolerance is h7 with a tolerance of 0/-0.015 mm for 4 mm bores.
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.
