Conical springs are a type of compression spring that because of their shape are also known as tapered or cone springs. The coil diameters of this type of spring are variable. They have a large outer diameter on one end and a small outer diameter on the other end. Due to the shape the rest of the coil diameters are variables as they increase or decrease in size (depending on how you see it) from one end to the other.
Our large stock spring department allows you to quickly search online through our stock conical tapered spring catalog using Conical Spring Finder. 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 since 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 stability. This is especially useful to replace a compression spring whose coil diameter is too small in proportion to its free length which causes a large slenderness ratio that can make the spring 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 are different. A barrel spring looks like a barrel which makes the top and bottom coil diameters small and the middle ones bigger. A barbell spring has the end coil diameters large and the middle ones small in the shape of an hourglass. That is why a barbell spring can also be called hourglass spring. All these are types of compression springs but differ from conical springs and regular compression springs because of their shape.
Conical 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.
