Belleville Washers & Disc SpringsA disc spring, also known as a Belleville washer or Belleville disc spring, consists primarily of a convex disc supported at the outer periphery by one force and an opposing force on the center of the disc. They are an ideal design solution where there is a high load requirement and space is limited.

Disc springs are used singly, or in stacks, to achieve a desired load and travel. The advantage of a disc spring is that it generates high force in a very short spring length and with minimal movement when compressed. All MWI disc springs are subject to exacting manufacturing and quality control standards. They are preset so that they will not significantly relax under load over time.

The Century Spring Corporation and Maryland Precision Spring locations of MWI specialize in the design, engineering, manufacturing, and stocking of the Belleville washers and disc springs products.

Types of Disc Springs & Belleville Washers

Alternative to steel elements that are up to 70% lighter weight, non-corrosive, and non-magnetic

CDM Disc Springs

Precision steel Belleville washers designed for dynamic loading

CDS Disc Springs

Steel Bellevilles for light bolted assemblies, sized for standard bolts

SP Series Disc Springs

For heavy bolted applications with a need to overcome thermal expansion and contraction. Stainless steel options for corrosion resistance

FL & MFL Series Flange Disc Springs

Elastic mechanical elements designed primarily for pipe flange applications

NDS Series Flange Disc Springs

Maintain tension and pressure around a flange especially under thermal variations or mechanical shock

Slotted Disc Springs

Slotted elements reduce the spring load and increase deflection

Springs for Ball Bearings

Especially designed for preloading springs use with radial ball bearings

Contact Disc Springs

For improved bolt connection applications, compensates for developed looseness, loss of bolt tension due to applied surface deterioration, or movement due to thermal changes

Curved Disc Springs

Cylindrical curve is well-suited for application requiring flexibility, light loads, and repeated cycles through a range of motion

Serrated Disc Springs

Serrated element ideal for use with almost any screw or bolt

Finger Disc Springs

Counteract noise, excess wear, end play, and vibration especially at high speeds

Wave Disc Springs

Efficient for obtaining the required load when the load is static, the working range is small, and the allowable amount of axial space is limited
