This International Standard lays down the dimensions and tolerances of housings for wiper rings used in reciprocating rod applications for fluid power cylinders. The range of sizes is from 6 mm to 360 mm rod diameters.
It includes the following three housing designs :
— Type A : recess housings with undercut or separate
cover to retain elastomeric wipers [see figure 1 and table 2 for normal series (pre-ferred)｜;
— Type B : open recess housings for wipers having
integral rigid reinforcement, that are a press-fit in the housing (see figure 2 and table 3);
— Type C : recess housings with undercut to retain
elastomeric wipers (see figure 3 and table 4 for reduced dimension series — recom-mended for use with cylinders conforming to ISO 6020/2).
This International Standard does not specify the style, configurations, materials or performance rating for the wiper ring.
