Flat Wire Compression Springs

Compression springs made from flat wire - wound to the spring axis - offer the advantage of higher energy absorption at the same installation space compared to round wire compression springs. Furthermore, flat wire compression springs are more resistant to buckling and will encounter no friction martensite at high frequencies -- unlike round wire compression springs, where the life expectancy is reduced. Our in-house rolling mills allow us to roll and process high-quality spring steels to the specific wire profiles our customers need. By choosing the right wire profile and spring dimensions, both linear and progressive characteristics can be realized.

Tension and Torsion Springs

We are able to offer our customers tension, torsion and individual form springs made of round, square or flat wire as well as of strip steel for all kinds of applications.

Steep Taper Standard Ball-End Runout Test Arbors

Ball end spindle runout test arbors are designed checking positioning accuracy of 5-axis machines, but can also be used in place of a standard runout test bars when a shorter length is required or for a touchoff point from the spindle face (ball end is ideal for this purpose).
