Self-locking rings provide a mechanical interference via a small tab on the ring that locks into a corresponding slot in the opposite turn and prevents the ring from expanding out of the groove as a result of centrifugal forces at high rotational speeds. The location of the locking mechanism can be dictated by the application requirements. Internal and external locks are easier to install (especially when small diameters or heavy cross-section material is involved) and allow for a simple visual confirmation of proper installation. Where tamper-proof applications are involved 'centreline' locks are typically used and once the ring is removed from an application, the tab is broken and a new ring must be installed. This type of locking feature is also less likely to interfere with mating components within the assembly.
