The S9901Z-G404-14 is a precision bellows coupling with a 0.2498-inch bore on the pin-type hub and a 0.312-inch bore on the clamp-type hub, designed for zero backlash torque transmission at speeds up to 2000 rpm and permissible angular misalignment of 5°. The bellows are made of phosphor bronze, the pin hub of brass, and the set screws of stainless steel. It features two #4-40 socket head set screws on each end, spaced 120° apart. Dimensions include A1 diameter of 0.2498 inch, A2 diameter of 0.312 inch, B1 diameter of 0.312 inch, and B2 diameter of 0.312 inch, with overall length of 1 ± 1/16 inch.
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.
