Overview
DIN 2093 disc spring washer is a standardized conical elastic fastener in accordance with German industrial standards. Different from ordinary flat washers, it features a unique conical disc structure that provides continuous elastic preload after compression. It effectively compensates for thermal expansion, mechanical vibration and bolt stress relaxation, preventing loosening and failure of threaded connections under dynamic loads. DIN 2093 covers standard A/B/C series specifications with precise dimensional tolerance, supporting single-piece use or stacked combination installation to meet different pressure and displacement requirements. With compact structure and ultra-high load performance in limited space, it is a core anti-loosening and buffer component for modern mechanical connections.
Material & Surface Treatment
All DIN 2093 disc spring washers are fully produced in accordance with EN10132-4 industry standard. Carbon steel versions adopt high-quality 65MN and C67S spring steel, processed with integral quenching and tempering heat treatment to achieve uniform hardness, stable elastic recovery and ultra-long anti-fatigue life. Phosphating treatment is applied for carbon steel surface, improving surface density, wear resistance and long-term rust-proof performance.
Application
DIN 2093 disc spring washers are widely applied in automotive transmission systems, motorcycle equipment, hydraulic machinery, engineering machinery, mold equipment, compressor units, precision automation devices, valve fittings and heavy-duty mechanical connections. Mainly used for bolt anti-loosening, gap compensation, vibration buffering, pressure maintaining and overload protection.

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,
