Bushings are cylindrical objects with one end turned down to produce a wider edge. On the outside, the turned down portion of the cylindrical part, often called the flange, produces 2 diameters (OD) & two lengths. Meanwhile the entire part has one inside diameter (ID), usually a clear hole drilled through but threaded in some...

Characteristics By far the most widely used type of spring, compression springs are designed to oppose compression and return to its uncompressed length when the applied force is removed. The potential applications for compression springs are limited only by the imagination. Dimensions Measurement Guide Hold the base of the spring in one hand, and the calipers...
-
Compression springs are the most common spring configuration that product manufacturers turn to when enhanced product functionality is desired. Used in automotive, aerospace, general industrial, medical and technology products, this spring type is used to resist applied compression forces or to store energy in the push mode. In more simple terms, compression springs contain the highest potential energy when the component is “compressed.”

A disc spring (sometimes called a “Belleville washer” after the inventor) 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...
-
An extension spring is a part that captures energy and develops force used to execute an action. The “initial tension” is created during manufacturing when the wire is rotated backwards during coiling. When you pull the spring apart, you are undoing the rotation, which develops force or initial tension. Extension springs are used in a...
