The WBB Series (Plain) provides a wider footprint than standard miniature bearings, allowing for improved load distribution and lubrication retention. Without an outer ring flange, these bearings fit into standard bores where axial space is available. Their stainless steel construction ensures they remain reliable in challenging environments, particularly in specialized micro-motors.
