Types of Disc Springs & Belleville Washers
Carbon Composite Disc Springs
- Alternative to steel elements
- Up to 70% lighter weight
- Non-corrosive
- Non-magnetic
- Available from MW Industries
Belleville Washers (Classic)
- Designed to meet high performance requirements of dynamic loading applications
- Typically made from High Carbon or Alloy steel
- Available from MW Industries
Belleville Washers (Pre-Stressed)
- Used to maintain load or tension in light bolted assemblies
- Sized for standard bolt sizes
- Pre-stressed
- Available from MW Industries
Belleville Washers (Heavy Bolted)
- Designed for heavy bolted applications
- Used when there is a need to overcome thermal expansion / contraction
- Stainless steel options for corrosion resistance
- Not pre-stressed – designed for static bolt applications only
- Available from MW Industries
Flange Disc Springs (FL / MFL)
- Elastic mechanical elements designed primarily for pipe flange applications
- Reactive power keeps bolt joint tight under all conditions
- Available from MW Industries
Flange Disc Springs (NDS)
- Maintain bolt tension and gasket pressure around the flange
- Stand up under the most severe conditions
- Automatically adjusts for thermal variation, vibration, and mechanical shock stress
- Available from MW Industries
Flat Washers (SFW)
- Made from 17-7 stainless steel
- Provide strength of heat treatment and corrosion-resistance
- Great for outdoor use or in harsh environments
- Available from MW Industries
Ball Bearing Spring Washers
- Especially designed as preloading springs for use with radial ball bearings
- Help to maintain positioning accuracy of the bearing
- Minimize vibration and shaft deflection
- Available from MW Industries
Slotted Disc Springs
- Slotted elements reduce the spring load and increase deflection
- Available from MW Industries
Contact Disc Springs
- Improved bolt connections – compensates for developed looseness, loss of bolt tension due to applied surface deterioration, or movement due to thermal changes
- Available from MW Industries
Curved Spring Washers
- Cylindrical curve is well-suited for application requiring flexibility, light loads, and repeated cycles through a range of motion
- Available from MW Industries
Serrated Disc Washers
- Serrated element ideal for use with almost any screw or bolt
- Available from MW Industries
Finger Spring Washers
- Counteract noise, excess wear, end play, and vibration
- Especially effective at high speeds
- Available from MW Industries
Wave Spring Washers
- 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
- Available from MW Industries
