Leading Precision Disc & Spring Washer Manufacturer
Leading Precision Disc & Spring Washer Manufacturer
Leading Precision Disc & Spring Washer Manufacturer
Introduction
In the realm of high-load mechanical assemblies, the reliability of fastening components is non-negotiable. Durga Spring stands as a premier precision disc & spring washer manufacturer, dedicated to producing high-performance conical spring washers that provide consistent tension and shock absorption. Our disc springs are engineered to handle extreme loads in limited spaces, making them indispensable for industrial valves, clutch mechanisms, and heavy machinery. By utilizing advanced heat treatment processes and high-grade spring steel, we ensure that every washer maintains its elastic properties even under severe cyclical loading conditions.
Why Choose Our Precision Spring Washers?
As a specialized precision disc & spring washer manufacturer, we understand the nuances of spring rate, fatigue life, and deflection. Our production process involves:
- Material Integrity: We use premium 50CrV4 (DIN 1.8159) and stainless steel grades to prevent relaxation and ensure long-term durability.
- Tight Dimensional Tolerances: Our CNC-controlled manufacturing ensures that inner diameters, outer diameters, and thicknesses are maintained within microns for perfect fitment.
- Advanced Surface Engineering: From phosphating to zinc plating and mechanical cleaning, we offer finishes that protect against corrosion and hydrogen embrittlement.
Applications & Benefits — High-Performance Disc Springs
Industrial Applications
- Actuators and high-pressure valve assemblies in oil and gas.
- Clutch and brake systems in heavy-duty commercial vehicles.
- Vibration damping in power plant turbines and generators.
- Maintained bolt tensioning in structural steel construction.
- Torque limiters and safety couplings in automated machinery.
Key Performance Benefits
- Superior load capacity within minimal installation space compared to coil springs.
- Predictable spring characteristics through modular stacking (parallel or series).
- Effective compensation for thermal expansion and contraction in bolted joints.
- High fatigue life under dynamic loads due to optimized stress distribution.
- Damping effect that protects machinery from sudden impact or vibration.
Engineering Excellence in Washer Production
- Utilization of precision stamping and fine blanking for burr-free edges and smooth profiles.
- Custom engineering capabilities to develop non-standard disc springs for specific load-deflection curves.
- Rigorous testing protocols including load testing, hardness checks, and salt spray testing.
- Compliance with international standards such as DIN 2093 and ISO specifications.
- Expertise in both small-batch specialized washers and high-volume industrial supply.

Maintenance & Safety Tips — Maximizing Washer Performance
Checklist
Durga Spring
Installation Guidelines
- Always verify the stacking sequence (series vs. parallel) to ensure the desired load and deflection are achieved.
- Ensure the guide rod or sleeve is hardened and lubricated to minimize friction during the compression of the disc spring stack.
- Check for alignment to prevent lateral loads, which can cause uneven wear or premature failure of the spring washer.
Safety & Maintenance
- Inspect washers periodically for signs of fatigue, cracks, or permanent deformation, especially in high-cycle applications.
- Avoid over-compressing the disc spring to its flat position unless the design specifically permits it, as this induces excessive stress.
- Replace any washer showing corrosion pitting immediately, as these pits act as stress risers that lead to rapid fracture.
FAQs about Precision Disc Springs
Q1 What is the difference between a disc spring and a standard spring washer?
Disc springs (Belleville washers) are designed for high-load, precision engineering applications with specific load-deflection curves, whereas standard spring washers are typically used for basic vibration resistance in general bolting.
Q2 Can you manufacture disc springs to DIN 2093 standards?
Yes, as a precision disc & spring washer manufacturer, we strictly adhere to DIN 2093 specifications for dimensions, tolerances, and material requirements.
Q3 What materials are available for high-temperature applications?
For high-temperature environments, we produce washers using Inconel, stainless steel 316, or specialized heat-resistant alloy steels that maintain tension at elevated temperatures.
Q4 Do you provide customized disc spring sizes?
Absolutely. We specialize in custom disc springs tailored to your specific load, space, and environmental requirements, including custom thicknesses and diameters.
Q5 How do you ensure the fatigue life of your spring washers?
We use shot peening to introduce compressive residual stresses and precise heat treatment to ensure an optimal grain structure, significantly enhancing the fatigue life of our products.
