Cylindrical Compression Springs
The spring has a uniform round pocket and needs a straightforward push-back action.
See best-fit usesChoose by what the spring needs to do
Start with the job inside your assembly: return a moving part, keep contact, fit into a shallow space, hold something in place or maintain an electrical connection. These guides explain where each spring style fits and what to confirm before you choose it.
Move it back
For buttons, levers, plungers and other parts that need to return to a known position after each action.
Application guide
The spring has a uniform round pocket and needs a straightforward push-back action.
See best-fit usesApplication guide
A simple pull-back spring connects directly to round pins, posts or eyes.
See best-fit usesApplication guide
Two simple arms can bear directly against stops or moving parts around a pivot.
See best-fit usesApplication guide
One visible working arm drives the moving part while the opposite end is retained close to the coil.
See best-fit usesApplication guide
A shallow open wire form can provide return or clamping action without a full coil.
See best-fit usesFit more into less space
For designs where compressed height, a changing pocket or limited axial room matters more than using a conventional coil shape.
Application guide
Compressed height is tight and the coils can be arranged to nest inside one another.
See best-fit usesApplication guide
The surrounding space changes in steps or the design benefits from staged coil contact.
See best-fit usesApplication guide
Neither a straight cylinder nor a simple cone matches the available spring space.
See best-fit usesApplication guide
The assembly needs a small amount of axial compliance but has almost no height for a coil spring.
See best-fit usesApplication guide
More axial travel is needed than a single wave turn can provide, but overall height still needs to stay low.
See best-fit usesApplication guide
Only a small amount of axial take-up is needed in a washer-shaped space.
See best-fit usesControl opening and closing
For doors, covers, latches and rotating controls that need a pull, a turning force or assistance around a pivot.
Application guide
The extension spring needs a compact, controlled end profile around a fixed anchor.
See best-fit usesApplication guide
A compact extension-spring connection is needed around a linkage or small anchor.
See best-fit usesApplication guide
The two attachment points are intentionally offset from the coil centerline.
See best-fit usesApplication guide
Rotary force needs to be shared across two working arms around a common pivot.
See best-fit usesApplication guide
There is room along an axis but limited radial space for a conventional torsion coil.
See best-fit usesHold or locate a part
For clips, rings, brackets and custom wire shapes where the part must retain, guide, support or connect something in a specific space.
Application guide
The job is defined more by a custom wire shape than by a standard coil-spring category.
See best-fit usesApplication guide
A standard compression, extension or torsion layout cannot reach the required contact points or clear the available space.
See best-fit usesApplication guide
A component must be kept from moving axially on a shaft or inside a bore.
See best-fit usesApplication guide
A light, removable connection or retaining feature can be made from a simple wire path.
See best-fit usesApplication guide
A larger formed-wire structure can support, carry, guard or position the product.
See best-fit usesWork repeatedly under load
For dies, molds and fast repeated motion where operating stroke, duty and cycle life matter more than catalog size alone.
Application guide
Tooling needs high compression load, repeatable return and a standardized duty framework.
See best-fit usesApplication guide
A fast repeated system needs reliable closing force and control of moving mass through the full stroke.
See best-fit usesKeep parts in contact
For bolts, bearings, clutches and stacked assemblies that need force in a short axial space or need to absorb normal variation.
Application guide
The assembly needs substantial axial force in very little height.
See best-fit usesApplication guide
An annular spring needs defined fingers, slots or contact regions rather than a plain disc surface.
See best-fit usesApplication guide
Axial force needs to be distributed around a circular assembly and may be released through the center.
See best-fit usesApplication guide
A fastener, bearing or spacer stack needs a small amount of elastic axial compensation.
See best-fit usesApplication guide
The spring element sits directly under a fastener and must work as part of the bolted joint.
See best-fit usesApply force around a circle
For seals, circular grooves and connector interfaces that need distributed force or repeated engagement around a circumference.
Application guide
A seal or circular part needs continuous radial loading around its full circumference.
See best-fit usesApplication guide
A circular groove needs repeated multi-point contact, latching or controlled insertion force.
See best-fit usesMaintain a reliable contact
For batteries, grounding points, enclosure seams and switch interfaces where spring force works together with an electrical contact requirement.
Application guide
A removable enclosure seam or connector joint needs a reliable conductive contact path.
See best-fit usesApplication guide
A shallow strip can flex from a fixed area to provide return, retention or contact force.
See best-fit usesApplication guide
The spring must maintain electrical contact while also absorbing normal movement and tolerance.
See best-fit usesApplication guide
The user or mechanism needs a distinct snap action rather than a smooth linear return.
