ISO/TC 131/SC 7/WG 2 - Dimensions for seal housings

This document specifies dimensions and tolerances of housings for wiper-rings used in reciprocating rod applications for fluid power cylinders. The range of rod diameters is from 4Â mm to 450Â mm.

This document specifies the dimensions and associated tolerances for a series of hydraulic cylinder piston seal housings to accommodate elastomer-energized, plastic-faced seals used in reciprocating applications. This document does not stipulate details of seal design, since the manner of construction of seals varies with each manufacturer. The design and material of the seals, and any associated anti-extrusion components, are determined by conditions such as temperature and pressure. This document only applies to the dimensional characteristics of products manufactured in accordance with this document. It does not apply to their functional characteristics.

ISO 5597:2018 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 500 mm; - for rods of 6 mm to 450 mm. An additional range of seal housings is detailed in this document to meet the reduced envelope requirements of the 160 bar (16 MPa)[1] compact series of ISO 6020‑2; these smaller section seals require stricter piston rod and cylinder bore tolerances. The range of dimensions is as follows: - cylinders of 25 mm to 200 mm; - rods of 12 mm to 140 mm. ISO 5597:2018 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. ISO 5597:2018 only applies to the dimensional criteria of products manufactured in conformity with this document; it does not apply to their functional characteristics. [1] 1 bar = 100 kPa = 105 Pa = 0,1 MPa; 1 Pa = 1 N/m2.

ISO 10766:2014 specifies the preferred range of nominal dimensions and associated tolerances for a series of hydraulic cylinder piston and rod housings for rectangular-section-cut bearing rings, of the type shown in Clause 5, for applications in the following range of dimensions: for cylinders with bores of 16 mm to 500 mm, inclusive; for rods with diameters of 12 mm to 450 mm, inclusive. ISO 10766:2014 does not give details of cut bearing ring design, because the manner of construction of cut bearing rings varies with each manufacturer.

ISO 6195:2013 specifies dimensions and tolerances of housings for wiper rings used in reciprocating rod applications for fluid power cylinders. The range of rod diameters is from 4 mm to 360 mm. ISO 6195:2013 is applicable to the following five housing designs. Type A: recessed housings with undercut or separate cover to retain elastomeric wipers. Type B: open recessed housings for wipers with integral rigid enforcement, that are press-fit in the housing. Type C: recessed housings with undercut to retain elastomeric wipers (these are the preferred housings for double lip wipers without integral rigid enforcement). Type D: recessed housings with undercut to retain elastomer-energized, plastic-faced wipers. Type E: recessed housings with undercut or separate cover to retain elastomeric wipers (these are the preferred housings for single lip wipers without integral rigid enforcement).

This part specifies the dimensions and associated tolerances for a series of housings to accomodate seals used in reciprocating applications. Does not stipulate details of seal design. This part applies only to the dimensional characteristics of products. Does not apply to their functional characteristics. Figure 1 contains an example of housing. Table 2 covers dimensions and tolerances of housings for rod diameters from 6 to 360 mm.

ISO 5597:2010 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: cylinders 16 mm to 500 mm and rods 6 mm to 360 mm. An additional range of seal housings is detailed in ISO 5597:2010 to meet the reduced envelope requirements of the 160 bar (16 MPa) compact series of ISO 6020-2; these smaller section seals require stricter piston rod and cylinder bore tolerances. The range of dimensions are as follows: cylinders 25 mm to 200 mm and rods 12 mm to 140 mm. ISO 5597:2010 does not give details of seal design, since the manner of construction of seals varies with each manufacturer.

ISO 5597:2010 applies only to the dimensional criteria of products manufactured in conformity with ISO 5597:2010; it does not apply to their functional characteristics.

ISO 10766:2006 specifies the preferred range of nominal dimensions and associated tolerances for a series of hydraulic cylinder piston and rod housings for rectangular-section-cut bearing rings, of the type shown in Figure 1, for applications in the following range of dimensions: for cylinders with bores of 16 mm to 500 mm, inclusive; for rods with diameters of 12 mm to 360 mm, inclusive. ISO 10766:2006 does not give details of cut bearing ring design, because the manner of construction of cut bearing rings varies with each manufacturer.The design material of cut bearing rings and any incorporated anti-extrusion component are determined by conditions such as temperature and pressure.

ISO 6195:2002 specifies dimensions and tolerances of housings for wiper rings used in reciprocating rod applications for fluid power cylinders. The range of rod diameters is from 4 mm to 360 mm. ISO 6195:2002 is applicable to the following four housing designs. Type A: recessed housings with undercut or separate cover to retain elastomeric wipers (these are the preferred housings for single lip wipers without integral rigid enforcement). Type B: open recessed housings for wipers with integral rigid enforcement, that are a press-fit in the housing. Type C: recessed housings with undercut to retain elastomeric wipers (these are the preferred housings for double lip wipers without integral rigid enforcement). Type D: recessed housings with undercut to retain elastomer-energized, plastic-faced wipers. ISO 6195:2002 does not otherwise specify the style, configurations, materials, or performance ratings for the wiper ring.

Specifies the preferred range of nominal dimensions and associated tolerances for a series of hydraulic cylinder piston and rod housings for rectangular-section-cut bearing rings. Does not give any details of bearing ring design.

Establishes the preferred range of nominal dimensions and associated tolerances for a series of housings as follows: for cylinders of 16 to 500 mm; for rods of 6 to 360 mm. For the compact series of ISO 6020-2 the ranges of dimensions are as follows: for cylinders of 25 to 200 mm; for rods of 12 to 140 mm. Does not give details of seal design. Applies to the dimensional criteria of products; does not apply to their functional characteristics.

Lays down the dimensions and tolerances; the range of sizes is from 6 mm to 360 mm rod diameters. Includes the following three housing designs: - type A: recess housings with undercut or separate cover to retain elastomeric wipers (preferred); - type B: open recess housings for wipers having integral rigid reinforcement; - type C: recess housings with undercut to retain elastomeric wipers (for reduced dimension series). Does not specify the style, configurations, materials, or performance rating for the wiper ring.
