WRAP SPRINGS

With square-cross sections ranging between 0.35 mm and 6.40 mm, used in various applications including as transfer elements in clutches.

Typical applications

CONSTANT FORCE SPRING
CONSTANT FORCE SPRING
CONSTANT FORCE SPRING

A constant force spring provides a very constant characteristic curve over a longer spring travel. This enables a constant force or a constant torque to be achieved, depending on the installation situation. Products in this group are used in quasi-static or dynamic fields of application and are usually designed for individual customers and for specific tasks.
