The S50HS9M2C04C04 is a one-piece helical coupling made of 303 stainless steel for constant velocity torque transmission with zero backlash, designed to accommodate angular misalignment up to 5° and lateral offset up to 0.075 mm while permitting no axial motion. It features a clamp-type bore connection with 4 mm and 5.6 mm bore diameters, a nominal outside diameter of 12.7 mm, and a torsional stiffness of 0.56 N•m per arc second. The coupling is 20 mm long with an overall length of 6 mm for the hub, and uses an M3 set screw for secure shaft attachment.
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.
