Basic type cylinders with end lock prevent dropping when air supply decreases or residual pressure is exhausted. Separate air piping is not required for locking. Locking position can be at retracted end or at both ends, depending on the cylinder model. A wide variety of options are available.

Guided type end lock cylinders are available with a variety of locking methods and locking options in one direction or both depending on cylinder model. Emergency stops and intermediate stops are possible. Locking position can be changed to accommodate an exterior stopper position or the thickness of clamped work pieces.
