Corrosion resistance, flexible rotation, anti-rust, no need for lubrication.
POM has a small friction factor, good wear resistance, and uses high-strength glass balls to rotate smoothly and reduce noise. Good electrical insulation, hardly affected by temperature and humidity;
There is little change in humidity and frequency range.
POM has excellent mechanical properties, and its strength can reach 50.5MPa, which is very close to metal. It is only 2.3% at 20, 21MPa, 3000h, and it is not affected by temperature, and the friction factor is small.
Good wear resistance and high fatigue strength.
Material: Polyoxymethylene (POM), known as “super steel” or “sai steel”, also known as polyoxymethylene. It can be used normally in an environment up to 90°C.
Ferrule: The inner and outer rings are made of POM material known as Saigang for longer life and more durable.
