The S57PY5-DUT0306 is a telescoping miniature universal joint with zero backlash, designed to transmit rotary motion while accommodating up to 1/4 inch of axial motion. It is constructed with 303 stainless steel body and 440 stainless steel balls, lubricated with a dry film and oil suspension. The unit has a closed length of 1.5 inches, an outside diameter of 0.31 inches, and supports a maximum operating speed of 10,000 rpm at 0° alignment. Torque capacity is rated at 16 ozf-in at 0°. It features a 3/16 inch bore and tapered end flanges. Angular misalignment up to 60° is allowable at 4,000 rpm. The design permits free angular orientation of tapped holes, and set screws are available on special order.
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.
