Features
The RW laminated spring is a short deflection form of spring and generally consists of two or more laminations.
The torque being the sum of the number of springs used, a maximum of 8 springs can be used in any one assembly,
providing increased torque in the least possible space.
Our standard range of maximum energy springs are designed for 90° maximum angular movement with an average fatigue life of 5000 cycles. However, special springs can be manufactured to provide higher fatigue lives and greater deflections.
