In high-temperature environments, it is addressed with heat-resistant stainless steel bearings filled with fluorine grease or grease-free bearings.
For use in high-temperature environments (100-260°C) such as heating furnaces and dryers, fluorine grease sealed bearings and grease-free bearings are suitable. Our company offers "heat-resistant stainless steel bearings / heat-resistant hybrid bearings" and grease-free bearings "TC series" that are ideal for high temperatures and vacuum environments where grease cannot be used.
