The bearings in commercial fans operate at high speeds and relatively light radial loads. These bearings may also operate under extreme high or low temperature conditions, as well as in locations that are difficult to maintain. Fan airflow is often used for conveying materials. Over time, materials will accumulate on the impeller, causing imbalance and even reducing the normal operating time and service life of the fan.

The challenges posed by these operating conditions have placed high performance demands on the configuration scheme of wind turbine bearings. DOS can solve these problems. Based on extensive on-site experience, DOS has developed a series of solutions for industrial fans. These solutions can improve cost-effectiveness and achieve fault free operation.
