Specialty
Springs
(Counterbalance Springs / Constant Force Springs
In
response to customer demand, Dudek & Bock, in 2009
expanded the product line to include the production of
counterbalance springs - also known as regulator springs,
spiral springs and/or constant force springs. These
springs are a form of a torsion spring, made of rectangular
material. This
spring type is commonly used in automotive seating and other
highly demanding applications.
As a result of these high performance requirements,
the torque delivered per revolution is linear for the first
360 degrees. These
springs are required to apply constant force until the 360
degree point of rotation as they store rotational energy when turned about the
center shaft.
Size range capabilities for these
counter-balance springs span from .047”
x .125 to .076” x .140” for small springs up to .093” x .375” to .160” x .625” for larger springs.
