China Spring Lock Washers Manufacturer, Supplier, Factory

Spring Lock Washers are essential components in a wide range of industrial and mechanical applications, designed to prevent loosening of fasteners due to vibration, thermal expansion, or other dynamic forces. Their unique spring action applies a continuous load, maintaining bolt tension and ensuring secure, reliable assemblies. We offer a comprehensive selection of high-quality spring lock washers, including specialized types such as Light Type Spring Lock Washers for applications with limited space and lower load requirements, Single Coil Spring Lock Washers which provide a robust, single-point contact for consistent pressure, and the more general-purpose Coil Spring Lock Washers. For applications where the primary function is to absorb shock and provide a spring cushion, our range of Coil Spring Washers is the ideal solution. Each variant is engineered to meet specific performance criteria, ensuring optimal functionality in your projects.

The Spring Lock Washer operates on a simple yet highly effective principle. When compressed under a nut or bolt head, the washer's helical or curved form flattens, storing energy like a spring. This stored energy exerts a constant force against the fastener, which counteracts any rotational forces that might cause loosening. This makes the Spring Lock Washer indispensable in environments subject to constant vibration, such as in automotive engines, heavy machinery, and electrical equipment. The design of a Spring Lock Washer ensures that it returns to its original shape after compression cycles, providing long-term reliability. For optimal performance, it is crucial to select the correct size and type of Spring Lock Washer based on the specific application's load, temperature, and environmental conditions.

Spring Lock Washer Product Specifications

Material and Design Specifications

• Material: Typically manufactured from carbon steel (Grade 1050, 1070), stainless steel (Grade 304, 316), or other alloys like phosphor bronze for corrosion resistance.
• Finish: Common finishes include zinc plating, galvanization, and plain (self-color) for stainless steel, offering protection against rust and corrosion.
• Design: Helical (single or double coil) or Belleville (conical) shapes designed to apply a continuous spring force.
• Standards: Conforms to various international standards such as ASME B18.21.1, DIN 127, and ISO 8779.

Key Performance Characteristics

• Temperature Range: Standard carbon steel washers perform reliably from -20°C to +120°C. Stainless steel variants can withstand temperatures from -100°C to +400°C.
• Reusability: While designed for single use in critical applications, Spring Lock Washers can often be reused in non-critical assemblies if they are not permanently deformed.
• Application: Ideal for use in bolted connections subjected to dynamic loads, thermal cycling, and vibrational stress across industries like aerospace, automotive, construction, and electronics.
