Reference products


Compression spring for high frequency ranges

Description: This special spring was designed for applications in the powder processing industry with preload and oscillation in very high frequency ranges. It has a double start coil to ensure parallelism during compression.
Material: C300

Compression and tension spring without torsion

Description: This special compression spring was designed for coating processes with very high ambient temperatures and corrosive atmospheres. It has a left and right-hand helix and relief holes to prevent twisting during compression.
Material: Inconel 625

Compression spring as a replacement for coiled springs

Description: This special spring with an outer diameter of over 60 mm was developed as a replacement for coiled springs in shock absorbers to prevent fatigue fractures.
Material: Maraging C350

Injection valve spring for installation space optimization

Description: This special spring with an outer diameter of less than 5 mm was designed for use in injection valves of marine diesel engines. Relief holes reduce the tension during compression.
Material: Maraging C300

Electric contact spring with high conductivity

Description: This special spring was designed for the semiconductor industry and has a surface coating and a six-start coil to achieve maximum electrical conductivity.
Material: copper-beryllium
