In the world of industrial fasteners, maintaining a secure and reliable connection is paramount. Spring washers are indispensable components designed to prevent the loosening of bolted joints due to vibration, thermal expansion, or other dynamic forces. These washers work by applying a continuous spring force against the nut or bolt head, which compensates for any slack that might develop. Among the various types available, Split Spring Washers are a popular choice due to their helical cut design that creates a sharp edge to bite into the bearing surface and the bolt head, providing excellent resistance to rotation. Similarly, split lock washers function on the same principle, often used interchangeably in many applications to maintain preload. For scenarios demanding higher spring action and load distribution, Split spring lock washers combine the features of both split and spring washers, offering superior locking performance. When a more uniform pressure distribution is required across a larger surface area, a Corrugated Spring Washer, with its waved or curved design, is the ideal solution, effectively handling varying loads and gaps.
A Spring Washer is characterized by its specific design parameters that dictate its performance in an assembly. The material, dimensions, load capacity, and working temperature range are all critical factors to consider for optimal selection and application. Below is a detailed breakdown of the standard specifications for our high-quality spring washers.
| Parameter | Description | Standard Range / Value |
|---|---|---|
| Material | The base metal used for manufacturing, determining strength and corrosion resistance. | Carbon Steel (Grade 1050, 1065), Stainless Steel (302, 316), Inconel, Phosphor Bronze |
| Surface Finish | Coating or plating applied to enhance durability and environmental resistance. | Zinc Plated, Galvanized, Black Oxide, Cadmium Plated, Passivated |
| Size (Nominal Diameter) | The internal diameter that fits the bolt shaft. | #2 to 1 inch (or M2 to M24 metric equivalents) |
| Load Capacity (Spring Rate) | The force exerted by the washer per unit of deflection. | Varies by size and material; typically 10 N/mm to 500 N/mm |
| Operating Temperature | The temperature range within which the washer performs reliably. | -60°C to +300°C (dependent on material; higher for Inconel) |
| Standards Compliance | International standards governing dimensions and performance. | ANSI B18.21.1, DIN 127, DIN 128, ISO 10683 |
