Industrial Belleville disc spring with an inner diameter of 1.531 in, an outer diameter of 2.75 in, and an overall height of 0.255 in. This conical washer-style spring serves as a compact preload element in mechanical assemblies, helping maintain bolt preload and accommodate dimensional tolerances with repeatable load characteristics. Its small thickness and larger diameters make it suitable for constrained-space applications where precise pre-load is required.
