This standard establishes the preferred range of nominal dimensions and associated tolerances for a series of hydraulic cylinder rod and piston seal housings for reciprocating applications in the following range of dimensions: for cylinders of 16 to 500 mm; for rods of 6 to 360 mm. An additional range of seal housings is detailed to meet the reduced envelope requirements of the 160 bar (16MPa) compact series of ISO 6020-2: these smaller section seals require stricter piston rod and cylinder bore tolerances. The ranges of dimensions are: for cylinders of 25 to 200 mm; for rods of 12 to 140 mm. It does not give details of seal design.
