Hydraulic cylinders are well-known linear motion workhorses in industrial machinery. They’re reliable, familiar, capable of high force, and affordable, but they’re not without disadvantages. The leading ones are fluid leaks, large footprint (with hydraulic power unit or HPU), cumbersome changeovers due to lack of programmability, and high maintenance costs.
The introduction of electric high force linear actuators means machine designers now have a choice. An electric rod actuator can replace a hydraulic cylinder and eliminate the need to clean up leaks.
