The S50GL2MA30H0812 is an antivibration flexible coupling designed to reduce vibration and eliminate resonance in high-precision servo systems. It features aluminum hubs and a molded rubber (FKM) center, with bore sizes of 8 mm and 12 mm, and an overall length of 42 mm. The coupling accommodates a maximum angular offset of 1.5°, lateral offset of 0.2 mm, and axial motion of ±0.3 mm, and operates within a temperature range of -10°C to +120°C. It has a rated torque of 6.3 N·m, a maximum rotational speed of 21000 rpm, a torsional stiffness of 540 N·m/rad, and a weight of 56 grams. The coupling provides zero backlash and high torsional rigidity while dampening vibration for quiet, high-response operation.
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.
