Constant force stainless steel 301 torsion spiral springs for
Power springs are identified by the many coils of strip material
stored in a case, barrel, or band, and connected to a central arbor
or shaft. When this shaft is rotated, the material starts to wind
flat against it. This action creates an increasing torque for as
many turns as it can be wound until there is no material left.
Pre-pressed or conventional power springs
Our capabilities of power springs range from 0.002 inch to 0.125
inch material thickness and from 0.030 inch to 3 inch material
widths. Power springs can be made using pre-stressed (back wound)
or conventional (from flat) methods. Pre-stressed power springs are
spooled to a special free diameter and back wound into a housing or
keeper, while conventional wound springs are manufactured and wound
in the flat state. The advantages of pre-stressed springs are that
it allows maximized torque from a specific material. Conventional
wound power springs, however, offer increased cycle life.

The clock spring (also referred to as a flat torsion spring) is
designed to produce a torsional force (circular movement). In
contrast to the tightly coiled motor spring on the previous page,
the clock spring has open coils that, when mounted correctly,
reduces fricton to zero. However, torque capacity is reduced as a
result. The standard range is made from rounded edge stainless
steel, which affords a better fatigue life.
Constant force spring
The constant force spring consists of strip material, which has
been shaped and pre-tensioned into a tightly wound roll. The spring
is used in a linear movement and produces almost constant force
throughout its deflection. Constant force springs can be fitted in
a number of ways and extended partly or completely. There is
practically no limit on extension speed and acceleration.
