Ebmotrix Bearings
1 / 5
Spherical roller bearings have two rows of rollers and mainly bear radial loads. At the same time, they can also bear axial loads in either direction. The outer ring raceway of this type of bearing is spherical, so it has excellent self-aligning performance and can compensate for coaxiality errors. They have a high radial load capacity and are especially suitable for working under heavy loads or vibration loads, but they cannot bear pure axial loads.
