What are the features of a hydraulic locking cylinder?
Hydraulic locking cylinders typically have emergency stop or “e-stop” features designed to go into effect when power is lost. These locking systems can feature a mechanical lock manually set at a particular location along a rod, or an automatic locking feature, or both.
What is the guide support ring on a hydraulic cylinder?
