RTW Internal Retaining Ring (DIN 472 Standard)

The DIN 472 standard defines a type of internal retaining ring designed for installation in bore grooves. These rings prevent axial displacement of bearings, washers, or internal components, ensuring structural stability and allowing for repeated assembly and disassembly.

Featuring dual-hole construction, they are compatible with internal circlip pliers for quick and secure installation. DIN-standard rings are dimensionally precise, making them ideal for heavy-duty assemblies, export machinery, and EU-compliant equipment.
