The S9932Y-M28438438 is a crowned tooth gear type flexible coupling with a 0.4375-inch bore, designed to accommodate angular, lateral, and axial misalignments while transmitting torque with minimal friction and no lubrication. It features a molded nylon sleeve and steel hubs, supports a maximum angular offset of 1° per hub, lateral offset of 0.016 inch per hub, and axial motion of ±0.040 inch, with a recommended shaft gap of 0.160 inch. The coupling operates at temperatures up to 180°F, has a maximum torque capacity of 781 lbf·in, and is rated for up to 8500 rpm with a power rating of 10.5 hp at 1750 rpm. It weighs 1.8 pounds and uses a 1/4-20 set screw for shaft attachment.
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.
