Such retaining rings are suitable for securing machine components which have non-square (radiuse
10、d or chamfered) edges, and for concealed assembly as illustrated in Figure 9. They have an eccentric form and several lugs of equal radial width uniformly distributed over their circumference. 2 Normative references The following referenced documents are indispensable for the application of this doc
