Introduction to UJK970 Series High-Temperature Bearings
The UJK970 Series is a high-performance bearing line specifically designed for ultra-high temperature, heavy-load, and highly corrosive environments. Utilizing special alloy steels, ceramic hybrid materials, and advanced solid lubrication technology, these bearings can operate stably for extended periods under extreme conditions ranging from 500°C to 1200°C. They are widely used in industries such as steel metallurgy, glass furnaces, chemical reactors, cement rotary kilns, and aerospace, offering exceptional longevity, low friction, and resistance to thermal deformation.
Key Features
Ultra-High Temperature Resistance: Made from high-temperature alloys (e.g., Inconel 600/800) or SiN ceramic balls, capable of withstanding temperatures up to 1200°C.
Corrosion & Oxidation Resistance: Special surface treatments (e.g., carburizing, chrome plating) enhance resistance to acids, alkalis, and oxidation.
Self-Lubricating Design: Built-in graphite, molybdenum disulfide (MoS), or PTFE lubrication layers for maintenance-free operation.
High Rigidity Structure: Optimized internal raceway design minimizes the risk of seizing due to thermal expansion.
Multiple Configurations Available: Offers deep groove ball, cylindrical roller, angular contact, and other designs to suit varying load requirements.
