The S50FP9-FBC12515 is a Fairloc® bellows coupling with a 0.125 in. bore, 0.921 in. overall length, and brass hubs with phosphor bronze bellows for torque transmission while accommodating angular and parallel misalignment, end play, and vibration. It uses a #2-56 socket head screw and provides zero backlash with constant angular velocity. The coupling permits up to 5° angular misalignment, 0.015 in. lateral offset, and 0.015 in. axial motion, with a maximum torsional torque of 120 ozf·in. The hub bore has a suggested clearance fit of 0.0001 to 0.0008 in. over the shaft diameter.
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.
