The S50GL2MA39H1214 is a compact antivibration flexible coupling designed for high-speed servo and stepping motor applications, featuring aluminum hubs and a molded FKM rubber center to absorb vibration and eliminate resonance while maintaining zero backlash and high torsional stiffness. It accommodates shaft bores of 12 mm and 14 mm, with an overall length of 55 mm, and supports a maximum angular offset of 1.5°, axial motion of ±0.3 mm, and lateral offset of 0.2 mm. The coupling operates between -10°C and +120°C, with a rated torque of 13.5 N·m at 16,000 rpm and torsional stiffness of 950 N·m/rad. Shaft tolerances are 0/-0.018 mm for 11 to 14 mm diameters. The coupling is electrically insulating and designed for precision positioning in automation and semiconductor manufacturing equipment.
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.
