A perspective on fans. Bearings in industrial fans often operate at high speeds and relatively light radial loads. They may also operate in extreme temperatures, both hot and cold, as well as in inaccessible surroundings. Quite often the airflow is used to transport material, which will lead to build up on the impeller, creating unbalance. This will reduce uptime and the service life of the fan. Operating difficulties often put great demands on the bearing solutions in fans. From long and genuine experience, SKF has developed a range of excellent solutions for industrial fans as well as HVAC. These solutions improve cost-efficiency and provide trouble-free operation. |
