Curved Spring Lock Washers

Curved spring lock washers get surface treatments to work better and last longer. For example, zinc plating helps them resist rust, phosphating improves friction (so they grip better), and passivating stainless steel removes tiny contaminants that could cause problems. Electroless nickel coatings offer even protection in high-temperature spots, while black oxide finishes cut down glare and provide some rust resistance. Heavy-duty industrial setups might use specialty coatings like Dacromet or Geomet.

Applying a surface coating not only prolongs the life of curved spring lock washers, it also improves functionality.Lubricated coatings, for instance, reduce friction when you’re installing them, making the job easier. Properly prepping the surface ensures the washers can handle harsh environments, whether it’s a chemical plant, an offshore rig, or anywhere else with tough conditions.

Size Selection

Curved spring lock washers come in standard sizes (metric and imperial) to fit bolt diameters from M3 up to M100. The main measurements,outer diameter (OD), inner diameter (ID), and thickness,determine how much weight they can hold. If you need special sizes for things like tiny washers in electronics or extra-large ones for construction, those are available too.

The Xiaoguo® factory selects the right dimensions based on how much the curved spring lock washers needs to bend (deflection) and how much space there is. Following international standards like DIN 6796 means they can be swapped out easily and are good quality. The spec sheets include load-deflection curves, which help you figure out the best preload for your specific setup.

Factors that determine service life

Q: What factors affect the service life of curved spring lock washers in corrosive environments?

A:In a rust-prone environment, the length of time that curved spring lock washers can last depends on the material selected, its surface coating, and the severity of the environment.Stainless steel (like 316 grade) or nickel-alloy spring washers stand up to saltwater, acids, and chemicals way better than plain carbon steel without any coating. Electroplating with zinc or cadmium adds a protective layer, but it might wear off over time.

Always check curved spring lock washers regularly for rust, dents, or loss of tension and replace with new washers. In highly corrosive locations, standard spring washers can be replaced with non-metallic spring washers, such as those coated with silicone. Use the correct torque when installing to prevent excessive squeezing of the spring washers, which can accelerate material wear.
