Consultation with the manufacturer is recommended when making the appropriate selection from the available choices. NOTE This document includes a choice of axial length for every nominal piston and rod diameter, the exception being cylinders conforming to ISO 6020-2 in which case only one length is provided (see Clause 1 and Tables 4 and 6). 5.3 Radial depth The larger radial depth (cross-section) of the seal housing, S, shall be chosen where higher stresses or wider tolerances are involved. Consultation with the manufacturer is recommended when making the appropriate selection from the available choices. NOTE This document includes an alternative seal housing radial depth (cross-section) for most piston and rod diameters, the exception being at the upper and lower extremities of the diameter range as well as cylinder seal housings conforming to ISO 6020-2, in which case only one radial depth is provided. 6 Dimensions and tolerances NOTE See ISO 3320. 6.1 Piston seal housing dimensions 6.1.1 Illustrated examples of piston seal housing dimensions are given in Figures 1 and 2. 6.1.2 Piston seal housing dimensions (except in the case of cylinders conforming to ISO 6020-2) shall be selected from Table 3. 6.1.3 Piston seal housing dimensions for use with cylinders conforming to ISO 6020-2 shall be selected from Table 4. 6.2 Rod seal housing dimensions 6.2.1 Illustrated examples of rod seal housing dimensions are given in Figures 3 and 4. 6.2.2 Rod seal housing dimensions (except in the case of cylinders conforming to ISO 6020-2) shall be selected from Table 5. 6.2.3 Rod seal housing dimensions for use with cylinders conforming to ISO 6020-2 shall be selected from Table 6. 6.3 Radial seal space tolerances 6.3.1 Reference shall be made to Table 7 for radial seal space tolerances. 6.3.2 References shall be made to NOTES 1 and 2 of Table 7 for the formulae for calculating tolerances on d (see Figures 1 and 2) and D (see Figures 3 and 4). NOTE 1 The equations and values shown in Table 7, when used in conjunction with ISO 286-2 limits of D H9 and d 3 f8 (for the piston...
