DIN 471 External Circlip German Standard Shaft Retaining Snap Ring
Keywords：
Overview
DIN 471 external retaining ring is a standard fastener conforming to German industrial standards. It is installed on the outer groove of the shaft to provide axial positioning and anti-loosening protection for mechanical components. Different from DIN 472 bore circlips for holes, DIN 471 is specially customized for shaft outer diameter fixation. With elastic opening design and reserved pincer holes, the ring can be quickly expanded and installed, and tightly fits the shaft groove after rebound. It effectively avoids axial movement and vibration displacement of accessories during high-speed operation, greatly improving the stability and safety of mechanical operation.
Features & Advantages
Our DIN 471 circlips are manufactured in full compliance with EN10132-4 standard, adopting premium spring steel 65MN and C67S for carbon steel versions and SS420 for stainless steel versions. All carbon steel circlips undergo professional heat treatment to achieve consistent hardness, superior elastic recovery and excellent fatigue resistance, with phosphating finish as the surface treatment for effective rust prevention and improved wear resistance. The SS420 stainless steel circlips are processed with burr-free finishing, featuring smooth surface, high hardness and great corrosion resistance, perfectly suitable for precision mechanical assembly and various harsh working environments.
Application
DIN 471 shaft circlips are widely used in automotive industry, motorcycle parts, gearboxes, reduction motors, hydraulic pneumatic components, pumps, compressors, construction machinery, home appliances and precision automation equipment for fixing bearings, gears, sleeves and other transmission parts.

Frequently Asked Questions
product
What core advantages does standard DIN471 external circlip have over non-standard snap rings?
Produced per DIN471 & EN10132-4, it features precise dimension matching standard grooves. Made of 65Mn/C67S, it delivers outstanding anti-fatigue performance and resists loosening under long-term vibration.
How to maintain DIN472 when elastic weakness appears during equipment inspection?
Fatigued circlip cannot be restored; replace with brand-new DIN472 and forbid repeated usage of deformed old parts.
Standard installation operation of DIN6799 circlip?
Align E opening with shaft groove and press down vertically with flat screwdriver until fully seated.
Benefit of phosphated surface for DIN2093 during component service?
Phosphating improves rust and wear resistance to extend service life of DIN2093 inside hydraulic cylinders and high-pressure valves.
Self-locking fixing principle of DIN1481 slotted spring pin?
Slotted body shrinks during pressing and rebounds to expand against hole wall, forming radial preload for self-lock positioning.
business
How to select material of ISO8752 reasonably for different working environments?
Choose 65Mn black oxide carbon steel for dry indoor machinery, auto chassis and general reducer; switch to stainless steel ISO8752 for damp, oily and corrosive working conditions like water pumps and food equipment.
Correct disassembly method for DIN1 during mould maintenance?
Eject DIN1 from opposite end via pin punch; violent hammering is forbidden to avoid bore deformation.
Solution for stuck DIN7 taper pin during equipment overhaul?
Knock out from big end; drill and replace new DIN7 if severely rust locked.
Heat treated quenched steel strip includes blued strip and polished strip, what are respective advantages of two surface types?
All heat treated quenched steel strip is fully quenched with high hardness and stable elasticity. Blued steel strip forms uniform blue oxide layer for natural rust resistance with high cost performance; polished steel
What are the core advantages of annealed steel strip compared with semi-hard strip and heat treated quenched steel strip?
Made from 65Mn, C67S and other spring steel grades, annealed steel strip gets full full-annealing stress relief treatment. It owns the best ductility among three types of steel strips, hardly cracking during bending,
