China Light Type Spring Lock Washers Manufacturer, Supplier, Factory

In the realm of fastening solutions, ensuring joint integrity and preventing loosening under vibration is paramount. A key component for achieving this is the category of spring lock washers, which includes various specialized types designed for specific applications. Among these, our range of Single Coil Spring Lock Washers offers a robust and reliable solution for maintaining bolt tension. The broader family of Spring Lock Washers encompasses designs that provide a consistent spring force, crucial for dynamic load conditions. For applications requiring enhanced resilience and a specific coil geometry, our Coil Spring Lock Washers are engineered to deliver superior performance. Understanding the fundamental principle, a Coil Spring Washer functions by applying a continuous axial force, compensating for slack and material relaxation, thereby securing the assembly effectively.

The Light Type Spring Lock Washers are precision-engineered components designed for applications where a lower spring force and minimal weight are critical design considerations. These washers are characterized by their slender cross-section and reduced height compared to standard spring washers, making them ideal for use in compact assemblies, electronic enclosures, and lightweight machinery where space and mass are at a premium. Despite their light-duty designation, they are manufactured to exacting standards to provide consistent and reliable anti-loosening properties. The fundamental working principle remains the same: when compressed under a nut or bolt head, the Light Type Spring Lock Washer exerts a counter-force against the fastener, which helps to maintain clamp load and resists back-off caused by vibrations, thermal cycling, or dynamic stresses.

Key Technical Parameters of Light Type Spring Lock Washers

• Material: Typically manufactured from high-carbon steel (Grade C1065/C1070) or stainless steel (AISI 302/304/316), offering a balance of strength, spring properties, and corrosion resistance.
• Finish: Common finishes include plain (self-color), zinc plating (with or without chromate conversion coating), and galvanization for enhanced corrosion protection.
• Operating Principle: Functions as a spring to maintain tension in a bolted joint, preventing loosening under vibrational and dynamic loads.
• Standards: Conforms to industry standards such as DIN 127 B (Light Type), ANSI B18.21.1, and ISO 8752, ensuring interchangeability and specified performance.
• Temperature Range: Suitability depends on the base material and finish, generally effective from -20°C to +120°C for carbon steel, and up to +300°C for certain stainless-steel grades.
