ISO 8140: Rod-end clevis
ISO 8140 defines the mounting dimensions of rod-end clevises for pneumatic cylinders. Rod-end clevis attachments are also commonly called rod end forks. Rod end forks use female threads to attach to a male threaded piston rod. A load is coupled to the clevis attachment with a pivot pin.
Rod-end clevis attachments are suitable for linear (push or pull) and non-linear load travel. A rod-end clevis attachment provides a coupling to rotate about and keep the force transfer along the centerline of the cylinder during actuation. Spherical eye attachments can be used in applications where the load is pushed or pulled in a linear path.
