Attention is dr
7、awn to the possibility that some of the elements of this document may be the subject of patent rights. DIN shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 471:1981-09 as follows: a) normative references have been updated; b) the
8、specifications for load bearing capacity, detaching speed and assembly have been revised; c) the tolerances on radial run-out have been deleted from Figure 2 (formerly Figure 3); d) in Clause 10, Figure 11 (formerly Figure 14) “Taper assembly” has been revised; e) Figure 10 “Design of groove base” h

NOTE Retaining rings are used to hold components or assemblies (e.g. rolling bearing
11、s) on shafts and are suitable for the transmission of axial forces. 2 Normative references The following referenced documents are indispensable for the application of this document.
