The S50FP9-FBC31221 is a Fairloc® bellows coupling with a 0.3125-inch bore, 1.16-inch overall length, and a #4-40 socket head screw. It is designed to absorb shaft end play, correct angular and parallel misalignment, and provide zero backlash with constant angular velocity. The hubs are made of brass, the bellows of phosphor bronze, and the screws of 300 series stainless steel with a tin plate finish. It accommodates a maximum angular misalignment of 6°, lateral offset of 0.015 inch, and axial motion of +.020 / -.040 inch. The maximum torsional torque is 200 ozf·in. and maximum axial deflection is 0.8°.
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.
