KJ8D Applications

The KJ8D is a ball knuckle joint used as a rod-end mounting accessory on SMC C85 series round body air cylinders. Threaded M8, it couples the cylinder piston rod to a driven member while allowing angular articulation, accommodating slight misalignment and swinging motion in the load path. Typical uses include clamping, pushing, and pivoting mechanisms on automated equipment where the rod must connect to a moving lever or linkage rather than a fixed point.
