scope:

This part of ISO 6020 establishes metric mounting dimensions for medium series cylinders, 16 MPa [160 bar ¹⁾], as required for interchangeability of commonly used hydraulic cylinders.

The medium series dimensions are applicable to round head cylinders with bores from 25 mm to 200 mm and to both round and square head cylinders with bores larger than 200 mm, thus allowing a wider range of applications.

NOTE This part of ISO 6020 allows manufacturers of hydraulic equipment flexibility in the design of 16 MPa (160 bar) cylinders and does not restrict technical development; however, it does provide basic guidelines.

1) 1 bar = 0,1 MPa = 10⁵ Pa; 1 MPa = 1 N/mm².
