The S57PY4MDFU0519 is a miniature universal joint featuring a 5 mm bore and a length of 54.1 mm. It is constructed from 303 stainless steel for the body and 440 stainless steel for the balls, ensuring durability and resistance to wear. This joint is designed to provide zero backlash through a patented design that maintains close dimensional control of its components. The torque is transmitted via hardened steel balls operating in burnished sockets, and an elastic preload between components eliminates all clearances. The joint can operate at a maximum speed of 4000 rpm at 0¬8 and can accommodate a maximum operating angle of 20¬8 at 2000 rpm. It features sealed-in lubrication with a dry film plus oil suspension, which enhances its performance and longevity. The inverted design of the joint reduces both size and weight while improving torque capacity and inertia. Set screws are available upon special order, making it adaptable for various applications. This product is suitable for engineers seeking a compact and efficient solution for transmitting torque in precision applications.
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.
