Belleville washers or conical washers are the strongest type of spring washers available. These types of washers are also referred to as disc springs and feature a conical shape, which allows them to work like a heavy-duty spring and provide high spring loads in tight places.
Willie Washer — a family-owned, domestic manufacturer of special washers, stampings, and machined parts — implements strict quality control procedures throughout the manufacturing process to ensure our selection of disc springs do not underperform when subjected to specified loads over an extended timespan.
Belleville washers feature a convex disc that is supported by forces on the exterior and center of the disc. Disc springs are able to be configured singly or stacked to develop the optimal load. Belleville disc spring washers are able to achieve extensive forces with short spring lengths. Conical washers produce little to no movement throughout the compression process.
Belleville disc spring washers feature a conically shaped disc form.These types of conical washers will deflect overtime at a specified rate. These disc springs are used in industries such as pump manufacturing, valve development, and industrial automation. Conical spring washers maintain a high degree of tension and act as shock absorbers on vibrating parts, which keeps assemblies tight.
These Belleville washers also compensate for thermal expansion and contraction on bolted joints. Belleville washers or conical springs are designed to be used as a single spring or in a stack formation. Conical washers are able to be stacked in a uniform direction or in an alternating fashion for all types of applications.
If you need to support extensive loads in limited spaces, Willie Washer recommends investigating the use of Belleville washers. Remember, it is important to keep friction in mind stacking Belleville washers.
