Cylinder Replacement Data Sheet

00

Existing installation

A pneumatic cylinder cannot be swapped directly for a hydraulic one — hydraulics run at 25 to 35 times the pressure, so the circuit around it changes too. This answer decides what we quote.

Pneumatic cylinderCompressed air, typically 6 bar. Converting to hydraulic. Hydraulic cylinderLike-for-like replacement or an upgrade. Nothing fitted yetSized from the load and the geometry instead.
