This International Standard establishes port dimensions1) for 160 bar2) (16 MPa) compact series cylinders as required for interchangeability of commonly used hydraulic cylinders.
NOTE — This International Standard allows manufacturers of hydraulic equipment freedom in design of metric cylinders; it does not restrict technical development but provides basic guidelines.
The compact series dimensions are most applicable to square head cylinders.
