This document 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 mm to 500mm;
for rods of 6 mm to 450mm.
An additional range of seal housings is detailed in this document to meet the reduced envelope requirements of the 160bar (16MPa)1 compact series of ISO6020‑2; these smaller section seals require stricter piston rod and cylinder bore tolerances. The range of dimensions is as follows:
cylinders of 25 mm to 200mm;
rods of 12 mm to 140mm.
This document does not give details of seal design, since the manner of construction of seals varies with each manufacturer. The design and material of the seal and any incorporated anti-extrusion components are determined by conditions such as temperature and pressure.
This document only applies to the dimensional criteria of products manufactured in conformity with this document; it does not apply to their functional characteristics.
