The S50XUTM series consists of cross joint type flexible couplings with aluminum alloy hubs, steel pins, polyimide bushings, stainless steel spacers, and black oxide steel screws. These couplings provide zero backlash, high torsional stiffness, and high torque capacity with maximum angular offset of 1° and lateral offset of 0.2 mm. Shaft bores range from 3 mm to 12 mm with h7 tolerances. The series offers rated torques up to 12 N·m, max rotational speeds up to 25,000 rpm, and torsional stiffness values up to 900 N·m/rad. Weight ranges from 8 g to 33 g depending on bore size. The maximum overall length listed is 27 mm, and no variant with a 30 mm length is included in the series.
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.
