The S59DZ9-HCF240423 is a heavy-duty constant-velocity coupling designed to transmit torque while compensating for angular misalignment up to 1° and eliminating backlash. Its hubs are made of aluminum, the flexible member is acetal, and the pins and screws are hardened alloy steel. It has a 0.250 inch bore, an overall length of 1.48 inches, and an outer diameter of 1.457 inches, secured with #8-32 socket head screws. It operates between -10°F and +150°F, offers electrical isolation, and requires no lubrication or maintenance. The continuous rated torque is 912 ozf·in with a torsional stiffness of 31.3 ozf·in per degree, and maximum shaft misalignment values are 0.019 inch lateral and 0.014 inch axial. The summation of all alignment factors must not exceed 50% of the rated torque.
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.
