17 Bearing Load and Life Information SM Series Motors Compumotor s SM Series and NeoMetric Series motors use ABEC5, double-shielded, prelubricated bearings. Bearing life is directly affected by radial and axial loading, along with operating speed. Engineering charts provide L1 life estimations for listed radial and axial forces applied to the motor shaft. This data includes the internal bearing preload and is for the shortest length motor in each frame. Longer motors will exhibit longer L1 life.
