22318MB/W33

 22318MB/W33 is a professional spherical roller bearing manufactured from high-quality bearing steel through forging and precision machining. It features stable structure, high rigidity, excellent self-aligning performance, heavy load capacity, strong impact resistance and outstanding wear resistance. Equipped with W33 annular oil groove and lubrication holes, it enables convenient lubrication and good heat dissipation. With reliable sealing performance, it can stably adapt to high-speed, heavy-load and dusty harsh working conditions. **Application** It is widely applied to heavy-duty rotating transmission parts of mining machinery, speed reducers, crushers, metallurgical equipment, cement machinery, fans, paper-making machinery, conveyor equipment and heavy industrial machine tools. **Usage Method** During installation, keep proper concentricity between the shaft and bearing housing, and make full use of its self-aligning function to compensate installation deviation. Fill with high-quality grease before installation and keep the seal intact. Avoid overloading, eccentric load and strong impact during operation. Inspect and refill lubricating grease regularly, clean dust and impurities in time, and prevent water ingress and corrosion to ensure stable operation. **Service Life** Under standard working conditions with professional installation and regular lubrication maintenance, its service life can reach 3 to 6 years. In light-load, clean and constant-temperature environments, it can serve more than 6 years. Under severe conditions such as 24-hour continuous operation, heavy dust, high humidity and heavy load, the service life is about 1.5 to 3 years. Standard daily maintenance can greatly extend its working life.
