The S50HS9M2P03P04 is a one-piece helical coupling made of 303 stainless steel, designed to compensate for angular and lateral misalignment while maintaining constant velocity in high- and low-speed applications. It features a set screw type connection with bore diameters of 3 mm and 4 mm, a total length of 20 mm, and a maximum angular offset of 5°. The coupling has a maximum lateral offset of 0.075 mm and no axial motion capacity. Torsional flexibility is rated at 3.5 N·m, and it supports a torsional stiffness of 18.9 arc sec/(N·m). The coupling is available in both set screw and clamp versions, with this variant using set screws 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.
