Extending Lubrication Interval of 260°C High Temp Fan Bearings
2026-04-21
Case Study: Fan bearings requiring extended lubrication intervals at 260°C continuous operation.
Recommended Products: FRTLUBE High Temperature Bearing Grease FL338A
Under the rigorous operating conditions of industrial fan bearings at high temperatures of 260°C, traditional mineral oil- or synthetic hydrocarbon-based greases suffer from issues such as oxidation, volatilization, and carbonization. This leads to drastically shortened lubrication cycles, and the resulting frequent downtime for maintenance severely compromises production continuity and economic efficiency.
Upon adopting FRTLUBE FL338A PFPE high-temperature bearing grease, its unique molecular structure—based on a perfluoropolyether (PFPE) base oil—demonstrates exceptional thermal-oxidative stability, low volatility, and chemical inertness. In extreme environments reaching 260°C, its lubrication performance is significantly enhanced, extending the lubrication cycle by more than 3 to 5 times while effectively reducing bearing wear and equipment failure rates.
FRTLUBE FL338A long-tern grease is engineered to perform reliably in extreme heat. Its advanced synthetic formula effectively resists oxidative degradation, volatilization, and viscosity changes, ensuring a stable lubricant lifespan and maintaining a consistent oil film even at temperatures up to 260°C. The carbon-fluorine molecular structure of the PFPE base oil provides exceptional thermal and oxidative stability, preventing decomposition, carbonization, or deposit formation that commonly cause bearing failures in high-temperature environments.
FRTLUBE FL338A is designed to be performance-equivalent to BARRIERTA L 55/2, the high-quality PFPE-based high-temperature grease from BARRIERTA L 55/2 High-temperature long-term greases. BARRIERTA products are known for long-term availability and service life over a wide service temperature range up to 260°C, particularly when exposed to aggressive chemical agents and vapours. FRTLUBE FL338A delivers comparable performance at a more competitive cost, offering an excellent value proposition without compromising on quality or reliability.
