Selecting bearings for environments exceeding 200°C requires careful consideration of materials, lubrication, and load ratings. Our technical team shares key factors to help you make informed procurement decisions.
Key Considerations
- Material Selection: Chrome steel bearings are suitable up to 120°C. For higher temperatures, consider stainless steel, ceramic, or high-temperature alloys.
- Lubrication: Standard greases失效 above 150°C. Use solid lubricants, perfluorinated compounds, or continuous oil bath systems for extreme heat.
- Clearance: High temperatures cause thermal expansion. Select bearings with increased internal clearance (C3 or C4 clearance).
- Load Ratings: Elevated temperatures reduce bearing load capacity. Apply temperature correction factors to your calculations.
