Barrel Spring

Our

barrel springs

are specially designed

compression springs

with a

wider middle diameter

and

narrower ends

, providing

better centering

, stability, and controlled deformation

under load

. They are ideal for compact structures requiring

reliable axial force

without

lateral deflection

.

    Key Features

    • Stable

      axial motion

      with

      minimal lateral shift

    • Higher buckling resistance than

      straight compression springs

    • Material options: stainless steel, music wire, phosphor bronze
    • Surface treatments: passivation, black oxide, zinc plating
    • Custom sizes,

      wire diameters

      , and

      spring rates available

    Applications

    • Push buttons and tactile switch modules
    • Medical instruments and compact actuators
    • Precision tools and optical devices
    • Automotive interior components
