External locking rings are installed on the Shafts ( GOST13940 - 86 , GOST13942 - 86 , DIN 471 ).
The name (designation) of the outer ring is its nominal diameter d , which is the nominal diameter of the shaft.
The size in the free state is the diameter of the ring d * measured inside .
The name is different from the size of the ring in the free state - the inner diameter of the outer ring in the free state is less than the name.
Attention! Between retaining rings according to GOST and DIN, there are differences that consist in the discrepancy between the thickness of the rings in some sizes (as a rule, DIN - vskie thicker). Although the standards almost repeat each other, there are nevertheless some sizes of rings, which have no analogues in another standard.
Therefore, in order to avoid errors, when ordering, we recommend calling the number GOST or DIN .
