The S59DZ6-TT040512 is a torque tube coupling with a 3.0 inch length, featuring bores of 0.2500 inch and 0.3130 inch on opposite sides, designed to accommodate angular misalignment up to 5° and transmit torque up to 25 lbf·in at speeds to 2000 rpm. It consists of an acetal torque tube and aluminum split hubs with clamp-type mounting, requiring no shaft flats or set screws, and provides zero radial play. The coupling is a one-piece assembly with an internal compression spring to prevent axial backlash and is intended for use in business machines, computer peripherals, printing equipment, packaging machinery, and servomechanisms.
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.
