Metal cage
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 |
Technical data
Surface roughness
| Roughness | Dynamic surface area | Static surface area | Groove flanks |
|---|---|---|---|
| Ra | 0.1 - 0.4 µm | ≤ 1.6 µm | ≤ 3.2 µm |
| Rz | 0.63 - 2.5 µm | ≤ 6.3 µm | ≤ 10.0 µm |
| Rmax | 1.0 - 4.0 µm | ≤ 10.0 µm | ≤ 16.0 µm |
Chamfer
The chamfer length as well as the chamfer angle are determined by the rod seal.
