Roller bearing units are robust, ready-to-mount units that are lubricated and sealed at the factory for maximum service life. Pillow (plummer) block units can support rotating shafts while standing on a flat surface, or hanging on a wall or ceiling. The SKF ConCentra locking combines easy mounting and a concentric tight fit on the shaft for high speeds and low vibration.

• Factory lubricated and sealed, ready to mount
• Long service life with minimal or no maintenance
• Quick mounting on the support surface, quick locking on the shaft
• True concentric fit on the shaft for high speeds and low vibration
