The S50GL2MA15H0305 is a compact antivibration flexible coupling designed for servo systems to absorb vibration, eliminate resonance, and maintain torsional rigidity while accommodating misalignment. It features aluminum hubs and a molded FKM rubber center, with a 3 mm bore for one shaft and a 5 mm bore for the other, and an overall length of 30 mm. The coupling compensates for angular offsets up to 1.5°, lateral offsets up to 1.5 mm, and axial motion up to ±0.2 mm, and operates within a temperature range of -10°C to +120°C. It is rated for a maximum torque of 1.1 N·m at a reference speed of 42,000 rpm, with an inertia of 3.6 × 10⁻⁷ kg·m² and torsional stiffness of 82 N·m/rad. The shaft tolerance is graded h7 with a 0/-0.012 mm tolerance for bores up to 6 mm. Rated torque must be adjusted using temperature correction factors above 30°C.
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.
