The SMC JB floating joint has a male-threaded steel stud and a female-threaded port, and it helps correct misalignments between compact air cylinders and attached loads. When the movements of an air (pneumatic) cylinder's piston rod and an attached load are not precisely parallel to each other, the floating joint connects to the piston rod to help correct for the misalignment by +/-5 degrees. The floating joint connects to female-threaded sockets with a stud made of steel for strength and finished with a corrosion-resistant coating. A female-threaded socket on the opposite end of the floating joint connects to male-threaded piston rods, and a rubber dust cover helps keep contaminants out of the floating joint for prolonged operations. The maximum pressure of this floating joint is 145 pounds per square inch (psi) and it comes in several sizes to accommodate different piston rod bore sizes.
Pneumatic actuators fall into two classes: linear and rotary. Linear actuators move objects in straight lines, while rotary actuators turn objects, or rotate them in varying directions. Air cylinders (also called pneumatic cylinders), the most common type of linear actuators, use pressurized air to pull and push piston rods in and out of cylinder barrels. This motion moves mechanisms connected to the rods, or (for detached items) directs or blocks travel using rod-attached plates. Air cylinders execute pushing, pulling, lifting, lowering, pressing, and stopping functions, and they come in several different body types, including round, compact, tie-rod, guided, slide, and clamp. Pneumatic cylinders can be either single acting, with one compressed air port to push the rod in a single direction and uses a spring to return the rod, or double acting, with two compressed air ports on opposite ends of the cylinder to both extend and retract the rod. For quieter piston operation, air cylinders can come with cushioning in one or both ends of their barrels. Several mounting styles are available both for attaching the air cylinder ends to moving components in a pneumatic system and for mounting to rigid surfaces. Air cylinders are used in industrialized automation applications in automotive, food processing, material handling, and robotics industry applications, among others.
