The S50HAA-075P0505 is a flexible helical coupling with one-piece 7075-T6 aluminum construction and clear anodized finish, designed to transmit torque while compensating for angular, lateral, and axial misalignment in non-reversing applications. It has a 3/4 inch bore diameter, a 0.157 inch shaft relief, and a 1.12 inch length. The coupling accommodates up to 5° angular offset, 0.010 inch lateral offset, and ±0.010 inch axial motion. Its maximum momentary torsional torque rating is 10 lbf•in for non-reversing applications. The part includes a #6-32 set screw and has a torsional inertia of 21.6 × 10⁻⁵ lb•in²•sec² based on the smallest standard bore. The coupling is nonmagnetic and suitable for high- and low-speed applications.
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.
