New sleeve bearing fans with MagFix system for temperatures up to 85 °C

With the high operating temperature of up to 85 °C, this innovative fan generation by SEPA EUROPE opens up a wide range of new applications for the user, not least the automotive sector. The term MagFix stands for magnetic fixation (positioning) of the fan propeller/rotor in sleeve bearing fans.

The sleeve bearing as used in fans only allows for a positioning of the rotor shaft in the radial and not in the axial direction due to its design. Thanks to the use of highly precise and reliable sintered sleeve bearings, it was possible to intelligently solve the problem of the considerable increase in the operating temperature. A special feature of this bearing technology is not only the treatment with thermally stable lubricants but also the magnetic pull that enables smooth running in all installation positions. An additional feature of the fans is the extraordinary high life expectancy of 210.000 h (MTBF). Many of the extremely robust and durable high-temperature fans are available as standard models, however they can be adapted accordingly to meet the individually required parameters (size, tacho output, PWM input, input voltage, connector assembly).
