Disc springs and washers, from standard steel and exotic materials, to satisfy any application.
A 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.
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. All discs springs 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.
Disc Spring Products offered include:
Carbon Composite Disc Springs
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
Serrated Disc Springs
Serrated element ideal for use with almost any screw or bolt
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
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
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
Springs for Ball Bearings
Especially designed for preloading springs use with radial ball bearings
Slotted Disc Springs
Slotted elements reduce the spring load and increase deflection
Finger Disc Springs
Counteract noise, excess wear, end play, and vibration especially at high speeds
