International standard ISO 6020-3 hydraulic cylinders

Part 3: Compact series with bores from 250 mm to 500 mm
This part of ISO 6020 establishes metric mounting dimension for compact-series cylinders with bores from 250 mm to 500 mm,16 MPa 160 bar, as required for interchangeability of commonly used hydraulic cylinders.
NOTES
1 This part of ISO 6020 allows manufacture of hydraulic equipment flexibility in the design of metric cylinders and does not restrict technical development but does provide basic guideline.
2 the compact-series dimensions are most applicable to square-head cylinders.
This part of ISO 6020 only applies to the dimensions of manufactured products. It does not apply to their functional characteristics.
Bore size : 250-320-360-400-500mm
