As aerospace, energy, and heavy machinery sectors push operating temperatures beyond 350°C, demand for reliable high-temperature bearing solutions is surging. MTWB Customized Bearings is at the forefront of this evolution, delivering precision-engineered bearings that withstand extreme thermal conditions.
The bearing industry is experiencing a paradigm shift as advanced applications demand components capable of operating reliably at increasingly extreme temperatures. From next-generation aircraft engines to deep-well oil extraction equipment, the requirement for bearings that perform consistently above 350°C has become a critical success factor.
China high-temperature bearing sector is making significant strides, driven by national strategic initiatives and growing industrial demand. Key developments include:
Major Project Milestones: In April 2026, CNOOC Energy Development Co., Ltd. completed its “350°C High-Temperature Submersible Electric Pump Technology Research and Product Development – Thrust Bearing Procurement” project. Luoyang Bearing Research Institute Co., Ltd. secured the contract with a bid of ¥597,700, marking a significant step toward domestic substitution in extreme-condition oil and gas applications.
Overcoming Technical Bottlenecks: In the aerospace sector, as engine thrust-to-weight ratios increase, bearing operating temperatures have reached 350–500°C. Domestic bearings currently struggle to fully meet these demanding specifications. To address this gap, the Jing-Jin-Ji National Center for Technology Innovation has partnered with Beihang University to launch a “Next-Generation Low-Density High-Temperature Bearing Material” project, aiming to break overseas technological monopolies.
Product and Material Innovation: Chinese manufacturers are actively expanding their high-temperature portfolios. Jiangsu Luyue Bearing offers products including the 6215-2Z/VA208 350°C heat-resistant bearing. Meanwhile, domestic researchers are comparing the friction and wear performance of new GNG CSS-42L bearing steel across temperatures from room temperature to 350°C, and developing innovative thermal expansion control structures for micro-turbojet engines operating at 350°C and 85,000 rpm.
Global bearing leaders are pushing technological boundaries through material science breakthroughs:
SKF 350°C Maintenance-Free Bearing: According to Bearing News, SKF has introduced an extreme-temperature bearing capable of operating at 350°C without relubrication, featuring a graphite cage that provides continuous self-lubrication.
SKF ARCTIC15 Aerospace Steel: In November 2025, SKF unveiled ARCTIC15, a new bearing steel designed for next-generation aerospace engines. This material supports higher power density and rotational speeds, with testing scheduled for early 2026 in combination with ceramic rolling elements.
Academic Research and New Product Launches: A May 2026 study focused on M50 bearing steel—widely used in aerospace engine bearings now operating at 350°C—exploring Thermal-Assisted Ultrasonic Surface Rolling (HUSR) to enhance tribological performance. Additionally, Jiaxing Rongcan Bearing launched a high-temperature composite bearing in January 2026, while Germany’s igus released a new PTFE-free wear-resistant plain bearing in April 2025.
Whether SKF ARCTIC15 steel, graphite cage technology, or domestic nano-dispersion strengthening techniques, material innovation remains the primary driver of high-temperature bearing advancement.
Bearings operating at 350°C face challenges including:
Thermal expansion and dimensional stability
Lubricant degradation and loss of film strength
Reduced material hardness and fatigue resistance
Oxidation and corrosion at elevated temperatures
Advanced materials such as high-temperature steels, ceramics, and specialized coatings are essential to overcome these obstacles.
Aerospace and energy sectors are the primary drivers of 350°C bearing technology.
The aviation industry’s pursuit of higher thrust-to-weight ratios, combined with extreme downhole conditions in oil and gas extraction, directly fuels R&D investment and procurement of high-temperature bearing solutions.At MTWB Customized Bearings, we understand that standard bearings often fail when exposed to extreme thermal environments.
