The Custom DIN 2093 Conical Disc Spring Washers, also known as Belleville washers in Series B, are angular, conically shaped fasteners that deliver powerful axial spring force for maintaining preload in high-load bolted joints. Constructed from resilient alloy spring steel like 60Si2Mn or 50CrVA for exceptional elasticity and fatigue resistance, or stainless steel (304/316) for corrosion-heavy settings, these washers compensate for thermal expansion, bolt relaxation, and vibrational loosening. With a dₑ/t ratio of approximately 28 and h₀/t of 0.75, they adhere to DIN 2093 standards, offering outer diameters from 8mm to 112mm for versatile sizing. Ideal for heavy machinery, automotive suspensions, wind turbines, and industrial assemblies, they generate consistent tension to prevent joint failure. Duojia in Hebei, China, customizes these washers to specific load requirements, meeting ISO9001, ISO14001, and ISO45001 for quality and sustainability. With a monthly output of 10,000 pieces and fast global delivery, these conical disc springs provide an efficient preload solution, reducing maintenance by absorbing shocks and ensuring long-term stability in dynamic environments. Their robust design minimizes space while maximizing force, making them essential for engineers seeking reliable axial compensation in demanding applications.
These DIN 2093 Series B conical disc spring washers feature a tapered, disc-like structure that compresses under load to produce spring-like axial force, ideal for applications needing vibration damping and preload maintenance. Alloy steel options offer high resilience for cyclic loading, while stainless variants provide rust-proofing in wet or chemical exposures without sacrificing elasticity. Sizes span outer diameters of 8mm to 112mm, with precise ratios ensuring optimal deflection and force output. Duojia’s forming process guarantees uniform thickness and angle, certified by SGS for fatigue life and performance. Installation places the washer between the bolt/nut and component; tighten to compress, creating tension that counters loosening—stack multiple washers for increased force or travel. Avoid exceeding the rated load to prevent flattening, and monitor for fatigue in high-cycle uses, replacing as needed. Suited for wind power generators, automotive components, and heavy equipment, these washers enhance joint reliability by absorbing expansions. With custom sizing available, minimum orders of 100 pieces, and 14-30 day delivery in secure packaging, they are exported worldwide, offering a compact, high-force solution for stable fastening in space-limited assemblies.

DIN 2093 Conical Disc Spring Washers in Series B provide dynamic axial preload through their conical shape, generating high spring force in minimal space to compensate for bolt stretch and thermal variations, surpassing flat washers in vibration control. Alloy steel construction ensures fatigue resistance for millions of cycles, while stainless options add non-corrosive reliability in harsh climates without embrittlement. Customizable stacking allows tailored force-deflection curves, with precise ratios optimizing energy absorption for specific loads. Duojia’s production enables bespoke dimensions and materials, all tested for elasticity and preload consistency to prevent failures. These washers reduce joint creep by maintaining tension, ideal for bolted connections under fluctuating stresses, and their polished finish minimizes friction for smooth compression. Compact and stackable, they fit tight spaces while handling extreme pressures, requiring no special maintenance beyond load checks. Sustainable manufacturing meets ISO standards, ensuring low environmental impact. This array of capabilities offers vibration damping, preload retention, and adaptability, making them a superior solution for applications needing resilient, space-efficient fastening with enduring axial support.
Custom DIN 2093 Conical Disc Spring Washers excel in providing axial preload for vibration-prone bolted joints across industries. In heavy machinery, they maintain tension in engine mounts or presses, absorbing shocks to prevent loosening during operation. Automotive suspensions use them to compensate for road impacts, ensuring consistent performance in vehicles. Wind power generators benefit from their role in turbine assemblies, countering cyclic loads for reliable energy production. Industrial equipment like valves or pumps employs these washers to handle thermal expansions, reducing maintenance in high-pressure systems. Duojia’s custom options support specialized uses in aerospace for secure, lightweight fastening under extreme forces. With simple installation between bolts and components, they enable quick setups, requiring periodic inspections for optimal preload. Their design minimizes downtime by stabilizing connections, enhancing safety in dynamic environments from manufacturing lines to structural builds. Versatile for both standard and custom projects, they improve efficiency and longevity in global applications, from automotive to renewable energy.
