The table below shows the materials that we can offer for metal cages and springs.

Application Material Standard Characteristics
Metal cage Non-alloy standard steel AISI 1010
(DIN 1624)
Cold rolled steel
Metal cage Nickel chrome steel AISI 304
(DIN 1.4301 - V2A)

PU

Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterised by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.

Chemical resistance Pure aliphatic hydrocarbons (propane, butane)
Mineral oils and greases
Silicone oils and greases
Water up to +50°C
Compatibility issue Ketones, esters, ethers, alcohols and glycols
Hot water, steam, alkalis, amines and acids
Temperature range -30°C/+90°C
-30°C / +110°C with our PUHT
