The S50XUVM17H04H06 is a metric Oldham coupling with 4 mm and 6 mm bore diameters on opposite hubs, featuring mild steel hubs with black oxide finish and a ductile iron spacer. It accommodates a maximum angular offset of 2° and a lateral offset of 0.4 mm, with a maximum operating speed of 20,000 rpm. The coupling transmits a rated torque of 5.5 N·m and a peak torque of 11 N·m, has a torsional stiffness of 1300 N·m/rad, and a moment of inertia of 1.1 × 10⁻⁶ kg·m². Two set screws per hub, spaced 90° apart, secure the shafts. The overall length is 20.4 mm, and it weighs 24 grams.
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.
