Conical spring washers feature a unique disc spring design that delivers high spring efficiency, providing 70-90% of the contact pressure of Grade 8.8-10.9 bolts. These washers are engineered to compensate for subsidence in screw connections and prevent loosening through friction-based locking, ensuring long-term reliability in demanding environments.
Ideal for critical applications such as pressure vessels, structural steelwork, and power transmission systems, conical spring washers maintain clamp load under vibration and thermal expansion. The low-profile design offers space optimization, saving up to 40% height compared to coil spring solutions.
Available in a range of materials including 65Mn steel, 316 stainless steel, 304 stainless steel, and carbon steel (Q235), these washers cater to diverse industrial needs. Surface treatment options include Dacromet, galvanizing, black oxide, zinc-chromate coating, nickel plating, and phosphating, enhancing corrosion resistance and durability.
Technical advantages include high spring efficiency, effective settlement compensation, friction-based locking compliant with DIN 6796, and space-saving design. These features make conical spring washers a reliable choice for securing bolted connections in various industries.
Customization options are available for materials, sizes, and surface treatments, supporting OEM requirements and specific application needs. Bulk orders and trial quantities are accommodated, ensuring flexibility for both small and large-scale projects.
