SMC NJ08 1 2-20UNF Floating Joint

The SMC NJ08 Floating Joint is a compact, 1/2-20 UNF threaded cylinder-rod connection from SMC's NJ series designed to tolerate misalignment in pneumatic systems. It accepts a 1/2-20 UNF threaded interface and features a floating joint design that accommodates angular and lateral misalignment between the rod and mating components, reducing side loads and wear on cylinder linkages. The NJ08 uses UNF end style and has an overall width of 1.61 inches, making it suitable for tight installations. Rated for up to 150 psi, it fits standard industrial pneumatic circuits and automation equipment that require a simple, reliable floating connection. Typical uses include coupling a cylinder rod to end-effectors, linkages, or tooling fixtures where precise axis alignment cannot be guaranteed, enabling smooth motion and simpler mechanical layouts without major cylinder repositioning. As part of the NJ Floating Joint lineup, the NJ08 is designed for standard 1/2-20 UNF ports and is readily sourced through SMC's distribution network and authorized suppliers.
