The S50MSX-094P37P37 is a flexible coupling with a 0.3750 inch bore and 0.984 inch overall length, designed to compensate for angular, lateral, and axial misalignment with zero backlash and maintenance-free operation. The coupling is made of aluminum alloy ASTM 7075, has a maximum angular offset of 5°, lateral offset of 0.002 inch, and axial motion of ±0.004 inch. It is secured with a #6-32 set screw. The coupling has a rated torsional stiffness of 122.04 lbf·in./deg and a moment of inertia of 0.81 oz·in.², with a maximum torsional torque of 13.28 lbf·in. and a maximum speed of 26,000 rpm. Its overall diameter is 0.945 inch, and the bore tolerance is +.0011/-.0000 for this size.
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.
