Stock Conical Springs

Conical springs are also known as tapered or cone springs because of their shape. The coil diameters of this type of spring are variable. They’ll have a large outer diameter on one end and a small outer diameter on the other end; the rest of its coil diameters are variables but they do become smaller (or larger depending on how you see it) as they get closer to the small end (or the large end).

We are a fast-growing spring company that is making the change for an ancient industry. At you can find several tech tools that’ll help you both in designing your spring as well as buying them instantly, on the spot. Search through our stock conical tapered spring catalog using our easy-to-use Conical Spring Finder which you’ll find at the top of every page. You must simply select the spring type at the top of the Spring Finder tool and enter one or more spring dimensions to find the ideal spring for your application. These springs are non-linear for they don’t have a constant rate of force per unit of distance traveled. Instead, they have an average spring rate which you’ll see in its specifications on our stock conical spring catalog.

Conical tapered springs are useful for many things. You can turn a regular compression spring design into a conical spring design in order to give it with stability in case the coil diameter is too small in proportion with its free length thus giving you a large slenderness ratio that’ll cause your spring to bend or buckle during deflection.

Barrel and barbell springs are another alternative similar to conical springs because they also have tapered shaped diameters but the shapes these springs make are either convex or concave meaning the coil diameters on the ends are the same size but the coil diameters in the center are either smaller or larger.

Tapered compression springs are also very useful when it comes to reducing solid height. They perform a telescope effect which means that the smaller coils sink into the larger coils as the spring deflects. It doesn’t necessarily have to telescope flat either as long as the mean diameter of the smaller coil meets the inner diameter of the larger coil, you’ll still be able to save space.
