The S50HAD-075H0808 is a split hub, low-inertia flexible helical coupling designed for non-reversing applications with a maximum momentary torque of 1.25 lbf·in. It features a 0.250 inch bore diameter, a 1.50 inch length, and is constructed from 7075-T6 aluminum with alloy steel cap screws and a clear anodized finish. The coupling accommodates up to 3° angular offset, 0.010 inch lateral offset, and ±0.008 inch axial motion. It has zero backlash, constant velocity, and a torsional inertia of 0.091 × 10⁻⁴ lb·in·s² based on the smallest standard bore. The coupling is nonmagnetic and uses an integral clamp for shaft retention.
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.
