External retaining rings — also called snap rings or circlips — are installed in grooves machined onto shafts to retain components such as bearings, gears, and housings in axial position. JLHY's external retaining rings are manufactured to DIN 471 / ISO 471 standards from spring steel (65Mn or equivalent) with precision-formed eyes for easy installation and removal using standard circlip pliers.

The precision-machined groove installation allows quick and secure axial positioning of components without additional fasteners. JLHY's external rings feature consistent ring thickness, proper eye dimensions for tool fit, and controlled hardness (HRC 47-52) for the right balance of flexibility and structural integrity.

Also available in stainless steel A2 for corrosive environments. External retaining rings are used across automotive, machinery, and industrial equipment applications. Contact JLHY for external retaining ring specifications, material options, and bulk pricing.
