The S50HAM-200H2020 is a split hub flexible helical coupling designed for industrial motor shaft applications with zero backlash. It features one-piece construction with a 7075-T6 aluminum body and alloy steel cap screws, clear anodized finish, and nonmagnetic properties. The coupling accommodates a maximum angular offset of 5°, lateral offset of 0.030 inches, and axial motion of ±0.010 inches. Its momentary torque capacity is 178 lb-in for non-reversing applications, or 44.5 lb-in for reversing, and it has a torsional deflection of 2.94 lb-in/sec². The coupling has a 0.625-inch bore and a 3.00-inch overall length, with 1/4-20 cap screws for clamping. Inertia is based on the smallest standard bore diameter.
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.
