The S50GT2MA39H1216 is a metric antivibration flexible coupling designed to reduce vibration and eliminate resonance in high-speed servo and stepping motor systems. It features aluminum hubs and a molded rubber (FKM) center, with steel cap screws in black oxide finish. The coupling accommodates a maximum angular offset of 1.5°, a lateral offset of 0.2 mm, and an axial motion of ±0.3 mm, with an operating temperature range of -10°C to +120°C. It has a rated torque of 13.5 N·m, a maximum rpm of 16000, a polar moment of inertia of 2.5 × 10⁻⁵ kg·m², a torsional stiffness of 1100 N·m/rad, and a weight of 105 grams, based on the maximum bore size. The shaft bores are 12 mm and 16 mm, with h7 tolerance of 0/-0.018 mm for bore sizes 11 to 16 mm. The overall length is 48 mm, and it uses M4 cap screws.
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.
