Flange-Mount Ball Bearing Units

Flange-mount ball bearing units are used to accurately mount load supports when the mounting surface is perpendicular to the shaft axis. They consist of a housing that secures and positions a ball bearing.
Units feature one-piece cast iron housing, solid base, wide inner ring bearing, dual heavy-duty contact-type seals, steel plate slingers on sides for dust exclusion, full self-alignment, grease fitting for adding lubricant. Set screw units have two set screws 120° apart in the inner ring. Eccentric locking collar units provide locking for one-directional applications. 
Bearings that are mounted within a flanged housing are used when the bearing mounting surface is perpendicular to a shaft axis. They are commonly available in two, three, or four-hole configurations.  Four-bolt flanged ball bearing units have a square shape with 4 holes for mounting to accomodate higher loads than two-bolt flanges.  As with our 2-Bolt Flanged Bearing Units, 3-Bolt Flanged Bearing Units and our Flangette Series, the 4-bolt flanged bearing units have bearings that can be moved and aligned to better accomodate long shafts.
