Overview
The Speedaire 6X481 rear clevis kit is a precision-engineered mounting component for 4-inch bore air cylinders. Featuring a durable cast iron construction, this clevis kit delivers the strength and durability required in demanding pneumatic systems. A rear rod clevis is a mounting component used to attach the rod end of a pneumatic or hydraulic cylinder to another part of a machine—allowing it to pivot smoothly when the cylinder extends or retracts. The 6X481 meets industrial standards for secure, repeatable mounting across a range of OEM and aftermarket applications.
