The Different Compression Spring End Types

Today we want to share with you one of the basics of compression springs: the type of ends they have. This is important to know when trying to decide what stock compression spring to select and which is the adequate one for your device or when trying to design the best spring for your needs. Knowing the different types of ends a compression spring can have will give you a clear understanding of the type of ends you need to look for or want and whether this is relevant or not for your spring design.

Most compression springs you will see have closed and squared ends or closed and ground ends, which are the most popular end types. However those are not the only type of ends a compression spring can have. Less common types of spring ends are double closed and square ends and open ends. There are several things to keep in mind when trying to understand what type of ends your compression springs should have. We will address each of the four different compression end types and their abbreviations here:

closed and square ends

CS = Closed and Squared

Definition: Closed and squared ends are the most common end type and have one closed end on each side of the spring, meaning both ends of the spring touch the previous coils thus squaring the ends off so the spring can stand up vertically straight.

closed and ground ends

CG= Closed and Ground

Definition:Closed and ground ends are first made as closed and squared ends that are later ground off at the bottom of each end so that the spring’s ends can be rough and flat enough to stand vertically on a surface.

double closed ends

DC = Double Closed Ends

Definition: Double closed ends have two closed coils on each end thus giving you 4 four closed coils in total. These can sometimes be used for even more stability when trying to prevent buckling.

open ends

O = Open Ends

Definition: All coils are open and have pitch in between them so all coils are active. Therefore, the active coils equals the same number as the total coils. Open ends are the least common type of ends.
