scope:

This International Standard 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. This International Standard is applicable to the f ollowing 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.
