NFPA Releases New Technical Standard
A new technical document has recently been published and is now available from the National Fluid Power Association (NFPA).
ISO 6195:2013 (supersedes ISO 6195:2002) Fluid power systems and components — Cylinder-rod wiper-ring housings in reciprocating applications — Dimensions and tolerances
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 five housing designs, types A through E. These housing designs are intended for use with the wiper rings according to Figure 1.
This International Standard does not otherwise specify the style, configurations, materials or performance ratings for the wiper ring.
ISO 6195 benefits cylinder manufacturers by establishing a standard series of rod wiper-ring seal housings that can be incorporated in their components. It benefits sealing device manufacturers by providing a standard series of housings for which they can create standard sealing devices for a global market.
