Internal retaining rings are installed in bores (holes) to retain components on shafts passing through the bore. JLHY's internal retaining rings are manufactured to DIN 472 / ISO 472 standards — the counterpart to external rings — from spring steel with controlled hardness and consistent dimensions for reliable performance in bore-groove applications.

Internal rings have eyes that sit inside the bore for installation and removal with standard internal circlip pliers. The ring expands into a machined groove in the bore wall, creating a shoulder that prevents axial movement of the shaft component. JLHY's internal rings feature consistent ring thickness and eye geometry for reliable tool engagement.

Used in automotive wheel hubs, transmission shafts, pump and motor shafts, and general machinery assembly. Available in stainless steel A2 for corrosive environments. Contact JLHY for internal retaining ring specifications and technical support.
