Our custom spring washers are either stamped, laser cut, or photochemically etched from a sheet/strip material. In most cases, after the blanks are made, the now-flat washers are formed, heat-treated as necessary and finished to the drawing’s specifications. Spring washers can be used alone or in stacks to achieve the desired load and travel.
Peninsula Spring takes pride in being an industry leader in the engineering, prototyping and manufacturing of custom spring washers. We can punch, cut, stamp or bend just about any shape imaginable.
Below are the three most common types of spring washers:
Curve washers can be designed and used in many devices where tight space constraints don’t permit the use of conventional wire springs. Of all the spring washers, curve washers offer the highest amount of deflection. Another advantage is that they can be used to take up “slack” in many designs where constant pressure is required. Curve washers are well suited for applications requiring flexibility and light loads (from ounces up to about a hundred pounds) and repeated cycles through a range of motion.
Wave washers are spring washers that are designed to offer a compression force and maintain a load or take up “slack” between two surfaces. The waves in the washer act like a compression spring in such a way that when a load if applied, the waves deflect. Wave washers are generally used when there is limited radial space. Peninsula Spring manufactures custom metal wave washers to almost any size or shape imaginable.
Belleville washers, also known as disc washers, are one of the most common types of spring washers. These conical shaped washers can be used alone or stacked. Depending on the application, Belleville washers can also be stacked in either parallel form, where the spring-rate remains unchanged, and the deflection increases, or in series form, where the deflection remains unchanged and the spring-rate increases; or you can stack a combination with both configurations. Since Belleville washers have a conical configuration, it enables them to support high loads with relatively small deflections and solid heights compared to helical springs. Belleville washers are often used to fix vibration, relaxation, bolt creep and thermal expansion problems where a high spring-rate with little deflection is required.
