The S50HAM-125H1010 is a flexible helical coupling with a split hub, designed for industrial motor shaft applications requiring zero backlash. It has a 1.25-inch outer diameter, a 0.313-inch bore diameter, and a length of 1.75 inches. The coupling is constructed from 7075-T6 aluminum with alloy steel cap screws and features a clear anodized finish. It accommodates up to 5° angular offset, 0.030 inch lateral offset, and ±0.010 inch axial motion. For non-reversing applications, the maximum torque capacity is 51 lb-in, and for reversing applications, it is 12.75 lb-in. The moment of inertia is 7.8 × 10⁻⁴ lb·in·sec². The coupling uses #6-32 cap screws and is nonmagnetic, one-piece, and designed for constant velocity.
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.
