7 Key Criteria for Selecting High Quality High Temperature Bearings

Choosing the right high temperature bearing requires evaluating multiple performance parameters. Based on industry standards and feedback from global procurement experts, these seven criteria are essential for ensuring optimal performance and longevity.

1. Operating Temperature Range

The primary specification. Verify that the bearing's rated temperature exceeds your maximum operating temperature by at least 20%. Standard high temperature bearings handle 150-350°C, while specialty bearings can withstand up to 800°C with proper cooling systems.

2. Material Composition

High temperature bearings use specialized materials:

• Stainless steel (AISI 440C) for up to 300°C
• Tool steel (M50) for 300-500°C
• Ceramic (Si3N4, ZrO2) for 500-800°C
• High temperature polymers (PEEK, PTFE) for lower loads but extreme chemical resistance

3. Lubrication System

Standard grease fails above 150°C. High temperature bearings use:

• Solid lubricants (graphite, MoS2, PTFE) for dry running applications
• Synthetic oils (PFPE, silicone) for continuous operation up to 300°C
• Self-lubricating cages made from bronze or PTFE composites

4. Load Capacity and Speed Rating

High temperatures reduce material hardness and load capacity. Request dynamic and static load ratings at your specific operating temperature from the high temperature bearing supplier. A general rule: derate load capacity by 10% for every 100°C above 200°C.

5. Dimensional Stability

Thermal expansion can cause bearing seizure or loss of preload. Premium high temperature bearings use controlled heat treatment processes that ensure dimensional stability within +/-0.005mm across the operating temperature range.

6. Cage Design and Material

The cage holds rolling elements in position. For high temperature applications, choose:

• Machined brass cages for temperatures up to 300°C
• Phenolic resin cages for temperatures up to 200°C with low noise requirements
• Stainless steel cages for temperatures exceeding 300°C
