Belleville Disc Spring: 10.2 mm ID, 2.25 mm OAH, 28 mm OD MPN:180005

The Belleville disc spring is a superior spring washer made from chrome silicon alloy steel with an ID of 10.2mm, outer axis height (OAH) of 2.25 mm, and an outer diameter (OD) of 28mm. It provides a more stable and secure grip compared to conventional springs due to its conical shape that increases friction with compressive force, which in turn resists slippage and holds tightly against the surface it contacts, making it ideal for various industries such as automotive, construction equipment manufacturing, transportation, and aerospace. This versatile spring washer is used to provide support and take up space under the head of bolts or screws and prevents rotational movement between the fastener and connected assembly in applications subjected to tension, vibration and shock. With its wide range of sizes available, Belleville disc springs are crucial components that offer high load capacity, repeatable performance, and long service life for both professional assemblers and do-it-yourselfers.
