The S50BPH-P18725033 is a heavy-duty set screw type hub bellows coupling with brass hubs and a phosphor bronze bellows, designed to accommodate angular and lateral misalignment in rotating shaft applications. It has bore diameters of 0.1873 in and 0.2498 in, and an overall length of 1.035 in, with set screws sized #2-56 and #4-40 respectively. The coupling permits a maximum angular offset of 6° and a maximum lateral offset of 0.015 in, with a torsional spring rate of 200 lbf/in and axial motion tolerance of +.020 / -.040 in. The finish is tin plating, and the set screws are stainless steel.
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.
