The S50HAA-112H1616 is a split hub flexible helical coupling designed for non-reversing applications, with a maximum momentary torque of 28 lbf·in and a torsional inertia of 19.2 × 10⁻⁵ lbf·in·sec² based on the smallest standard bore. It features one-piece 7075-T6 aluminum construction with a clear anodized finish, integral clamp, shaft relief, and nonmagnetic properties. The coupling compensates for up to 5° angular offset, ±0.010 in lateral offset, and ±0.010 in axial motion. It has an outer diameter of 1.50 in, a length of 1.50 in, and uses a #6-32 cap screw. The bore diameter is 0.500 in. Designed for constant velocity and zero backlash operation, it is suitable for precise, high-speed motion control where misalignment must be accommodated.
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.
