Designed for Ease of Use: Installation and removal of our DIN 471 External Circlips are designed for efficiency. Specialized circlip pliers allow for controlled expansion of the ring, enabling easy placement into machined grooves on the shaft. The inherent spring action then ensures a tight and secure fit. Key Advantages for Your Applications: Standardized Performance: Manufactured to DIN 471, ensuring consistent quality and interchangeability. High-Strength Material: Hardened spring steel (65Mn) provides exceptional durability and retention force. Corrosion Resistance: Black oxide finish offers protection against mild corrosion. Secure Shaft Retention: Effectively locates and retains bearings, gears, pulleys, and other components on shafts. Space-Saving Design: Offers a compact and efficient retention solution compared to other fastening methods. Ease of Installation & Removal: Designed for use with standard circlip pliers, simplifying assembly and maintenance. Wide Size Range: Available in a comprehensive range from d10 to d300, catering to diverse shaft diameter requirements. Ideal for: Automotive transmissions and axles Industrial machinery and equipment Bearing and seal retention Gearbox assemblies Electric motors and pumps Power transmission systems General mechanical engineering applications Product NameStandardMaterialDiameter Range (Shaft/Bore)Thickness (mm)External CirclipDIN 471Spring Steel (1.8159), Zinc-Plated1.5 mm – 200 mm (Shaft)0.3 – 3.5 mmExternal CirclipISO 8750Stainless Steel (AISI 304/316)2 mm – 120 mm (Shaft)0.4 – 2.5 mmExternal Retaining RingANSI B27.1Carbon Steel (ASTM A228), Zinc-Plated1/4" – 4" (Shaft)0.5 – 3.0 mmExternal CirclipJIS B 2804SCM435 Alloy Steel, Phosphate Coated3 mm – 80 mm (Shaft)0.4 – 2.0 mmExternal Retaining RingGB/T 894.1-202065Mn Spring Steel, Black Oxide4 mm – 100 mm (Shaft)0.5 – 2.8 mmExternal CirclipDIN 472Stainless Steel (1.4301/AISI 304)5 mm – 150 mm (Bore)0.6 – 4.0 mmExternal Retaining RingISO 13337Alloy Steel (42CrMo4), Galvanized6 mm – 200 mm (Bore)0.8 – 4.5 mmExternal CirclipANSI B27.2Stainless Steel (ASTM F899), Plain0.375" – 3" (Bore)0.6 – 3.2 mm
