When would you require a cushion bypass?

A cushion bypass is utilized to prevent damaging impacts at the end of a cylinder’s stroke when a load is present. In scenarios where the cylinder is loaded as it begins its stroke, the pressure dynamics change significantly. A sudden stop can create a shock in the system, leading to potential mechanical failure or damage. Implementing a cushion bypass allows for a more gradual deceleration, helping to cushion the end of the stroke and protect both the cylinder and the connected components from the forces generated during abrupt halts.

In contrast, a cylinder that is not in use wouldn't require a cushion bypass because there is no motion taking place. Similarly, while excessive fluid temperature can affect performance, it does not directly relate to the mechanics of stroke ending. Lastly, while extending a piston too quickly could cause issues, the primary function of a cushion bypass specifically pertains to managing the energy and forces involved at the end of a stroke when a load is present, rather than during the extension phase.
