This Indian Standard which is identical with ISO 6099 : 1985 ‘Fluid power systems and
components — Cylinders — Identification code for mounting dimensions and mounting types’ issued
by the International” Organization for Standardization ( ISO ) was adopted by the Bureau of Indian

Basic and Production Engineering Division Council.

The text of the ISO Standard has been approved as suitable’for publication as Indian Standard without :

Axial dimensions are determined from a reference point which

The meaning ofthe letters and ofthe sign + isgiven in5.1 to5.5.

5.1 Letter Z
Any group of two letters beginning with Z identifies a

5.2 Letter U
4.2 For a pin rod end, thereference point islocated at the
Any group of two letters beginning with U identifies an end

Any group of two letters beginning with W, X, Y, or Z iden-

5.4 Letter H
4.3 For a female threaded rod end, the reference point is
