The light, stiff body extrusion has Hydraulic rotary actuators and pneumatic rotary actuators may have fixed or adjustable angular strokes, and can include such features as mechanical cushioning, closed-loop hydraulic dampening (oil), and magnetic features for reading by a switch. If there is a high-inertia load, when the cylinder reaches the end of stroke the sudden stop can cause mechanical shock, with effects ranging from mild annoyance to serious risk. Bore 7. Twelve popular mounting kits can be assembled to the basic cylinder and are shown on the following pages. In hydraulic cylinders, special shaping or contour-ing of the cushion spear or sleeve has been employed to provide programmed deceleration for the unit.
