The S9901Z-G417-01 is a precision bellows coupling with brass set screw hubs and a phosphor bronze bellows, designed to transmit torque while compensating for angular misalignment up to 10° at a maximum speed of 2000 rpm. It has zero backlash and features two #4-40 socket head set screws at each end, spaced 120° apart. The shaft bores are 0.1200 inches in diameter with a tolerance of +0.0005/-0.0000 inch. The coupling is 1.25 inches long with a ±1/16 inch tolerance and has an overall diameter of 0.187 inches. It is available in clamp or set screw hub configurations, with the set screw type used here.
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.
