"Heat-resistant series" heat-resistant stainless steel bearings
This is a bearing that encapsulates fluorine-based heat-resistant grease in SUS440C stainless steel, which has superior heat resistance compared to SUJ2 bearing steel.
"Features" 1. The operating temperature is up to 250°C (excluding seal types). 2. SUS440C stainless steel has a smaller reduction in hardness and dimensional changes under high-temperature environments compared to SUJ2 bearing steel. 3. SUS440C stainless steel excels in oxidation resistance, which is significantly affected in high-temperature environments compared to SUJ2 bearing steel. 4. The inclusion of fluorine-based heat-resistant grease enables lubrication at high temperatures.
