The S50GL2MA15H series is a compact antivibration flexible coupling designed for servo and stepper motor applications, utilizing aluminum hubs and a molded FKM rubber center to absorb vibration while maintaining zero backlash and high torsional stiffness. It accommodates a maximum angular offset of 1.5°, axial motion of ±0.2 mm, and lateral offset of 0.2 mm for bore sizes 5 mm and 6 mm. The coupling operates between -10°C and +120°C, with torque ratings adjusted by temperature correction factors above 30°C. It has a rated torque of 1.1 N·m, maximum RPM of 42000, rotational inertia of 3.6 × 10⁻⁷ kg·m², torsional stiffness of 82 N·m/rad, and weighs 11 grams based on the maximum bore. The shaft bore tolerances are 0/-0.012 mm for 3 mm and 6 mm shafts.
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.
