Arc Springs

Global leader in arc spring

We work with the necessary know-how and always provide the perfect arc spring for your project

Arc springs are one of the applications with the greatest demand for FEM analysis at RPK Group. It is a good example of how Finite Element Analysis (FEA) is used to ensure a safe and optimized design of this type of springs.

Regarding the material, we use eddy current tested qualities of torsion and valve spring wires. Depending on your application, stresses, and space we can make them with round and profiled wire cross-sections. At RPK Group, we deliver these arc springs as single springs with a linear torque characteristic or as a spring set variant for multistage torque characteristics.  Our springs are manufactured in wire diameters from 2.00 mm to 5.00 mm, so they are ideal for various applications.
