Pulp and Paper Processing Equipment

Spherical roller bearings have two rows of rollers that are mainly used for withstanding radial loads and also axial loads in either direction. Self-aligning roller bearings have high radial load capacity, especially suitable for heavy load or vibration load, but can not withstand the axial load. Spherical roller thrust bearings have good self-aligning properties and can compensate for the coaxiality error.
