Sealed, lubricated-for-life hybrid bearings boost service life for variable frequency drive fans
A manufacturer of high quality fans, motors and control systems wanted to increase the service life of its motors with variable frequency drives to provide additional customer value.
The SKF solution
To meet this objective, the company replaced the all-steel bearings in their fan motors with SKF hybrid bearings. In addition to increasing bearing service life, hybrid bearings were also able to reduce the noise level of the motors.
Field tests report that the SKF hybrid bearings currently in use have doubled and in some cases tripled the service life of the motor, when compared to the all-steel bearing solution that was previously in place.
