Cylinder cushioning calculations
WebOur standard cylinders are designed according to DIN and ISO standards and are available in two series (maximum operating pressure: 160bar = DIN ISO 6020/1 and 250bar = ISO 6022 or DIN 2433). Piston rods of our standard cylinders are also hardened, ground and hard-chrome plated as standard.

WebJan 11, 2024 · Hydraulic Cylinder Cushions Can Prevent Mechanical Shock. A racecar on a track can stop one of two ways. If the driver applies the brakes, the reduction in speed is controlled and gradual. If the car hits the wall, the change in speed is abrupt and violent. The car will likely sustain mechanical damage as it absorbs the change in energy.

The cushion piston is an alternate solution to provide the cushion function and offers advantages over the spear-type cushion. This solution can be designed for a wide range of flows and can be more effective in a lower flow range than the spear type. The controlled flow passes through a single orifice, which allows more
