The S50HAWM20P0606 is a one-piece, zero-backlash helical coupling made of 7075-T6 aluminum for constant velocity transmission in high- and low-speed applications. It has a bore diameter of 6 mm, an outer diameter of 20 mm, and a length of 24 mm, with an M3 set screw. It compensates for up to 5° angular offset, 0.25 mm lateral offset, and ±0.25 mm axial motion. Its maximum momentary torque is 1.1 N·m, and its torsional inertia is 270 × 10⁻⁴ kg·cm² based on the smallest standard bore. Torque ratings are halved for nonreversing and quartered for reversing 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.
