The S50MSX-074P25P25 is a flexible coupling with a 0.2500 inch bore and 0.787 inch overall length, designed to compensate for angular offsets up to 5°, lateral offsets up to 0.002 inch, and axial motion up to ±0.004 inch. It features an aluminum alloy ASTM 7075 construction, set screw mounting, and zero backlash. The coupling has a maximum torsional torque rating of 8.85 lbf•in, a maximum rotational speed of 33000 rpm, a torsional stiffness of 41.71 lbf•in/deg, and a moment of inertia of 0.42 oz•in². It weighs 0.25 oz.
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.
