Bearings in industrial fans are typically operated at high speeds and a relatively light radial load. Fan bearings can also operate under extreme low or low temperatures; they can also operate in environments where protection is not easy. Airflow is often used to transport materials. The material will accumulate on the impeller; then it will lead to imbalance. This will increase the operating hours and operating life of the fan. The difficulty in operation generally demands high demands on the bearing disposal scheme in the fan.
Based on temporary practice, SKF has developed a range of outstanding disposal solutions for industrial fans and HVAC. These disposal options are cost-effective; end-of-the-road operation.
The most economical fan shaft bearing solution for oil-lubricated bearing systems is to disengage the bearings. Due to the problem of shaft alignment; it is recommended to adopt self-aligning bearings. A few years ago; only one doorway could accommodate the shaft of the shaft Shortening: The bearing on the non-positioning side slides in the bearing housing.
However, there is now a better disposal solution for the CSKF self-aligning bearing system. It adopts the SKF "seeker" spherical roller bearing on the positioning side; adopts the CARB on the non-positioning side? Toroidal roller bearings. The bearing system can accommodate misalignment; the elongation of the shaft is accommodated outside the CARB bearing; there is almost no conflict.
When oil lubrication is adopted; SONL series standard bearing housings are recommended. SONL housings are importantly used for oil bath lubrication; but they can also be used for circulating oil lubrication.
Any two applications are different. SKF provides you with the products and performances that are specifically designed for your application and unique conditions. We use our latest tips and accumulated application knowledge and experience to add value to our customers; Gain more surplus contribution power.

Low-temperature operation; without the need to switch to costly lubrication methods, the higher the fan speed; the more heat that occurs. This generally requires the conversion of grease lubrication to a more costly oil bath method; However; in many cases; does not adopt a more costly lubrication method; it can also advance the function of the fan.
The SKF Total Axis Disposal Solution for industrial and hot air fans disposes of all aspects of the low temperature problem; then it can advance speed; increase flow; increase energy consumption; enhance reliability; and extend the interval of the compensated lubrication.
High-performance fans that are lubricated with oil or circulating oil are used in applications where operation is performed at low temperatures; the circulating oil system is an extremely useful door for lubricating bearings and reducing temperature. SKF supplies several total shaft disposal solutions that can advance the benefits of wind turbines; High-performance fan lubricated in oil bath and circulating oil.
High-performance industrial fans operate at very high speeds; sometimes at low temperatures. Under these conditions; a single oil is used as a lubricant. Oil lubrication will ensure lower bearing operating temperatures;
The air handling unit SKF has developed a small number of products and efficiencies that have arrived at HVAC's professional pleading. For example; these products and efficiencies provide a sensitive and concise energy-saving doorway. They increase the need for protection; advance benefits and functions together. In addition; Degree of disposal plan; improve the mission environment.
In order to reduce the cost of maintenance; there are various disposal options to eliminate the most rare reasons for the premature results of the components; and then improve the overall economic benefits.
