Belleville Disc Spring: 4.2" ID, 0.7" OAH MPN:170010

The Belleville disc spring is an essential part used in fastening and hardware solutions where pressure or tension must be absorbed by the component. With its conical shaped disc design, it exerts a constant force acting radially against the mating surface of the assembly ensuring a tight fit for flange assemblies or retaining rings applications found on bolted joints or clamping systems in automotive, marine and aerospace industries. The ID size is 4.2 inches and OAH (overall axial height) measures at 0.7 inches which can support up to 65-80% of its diameter compressively providing consistent force distribution across the assembly without wearing out easily or losing elasticity over time making it ideal for demanding conditions requiring regular use where vibration resistance, low permeation of corrosive media, thermal stability are critical.
