Four Bolt Flanges

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.
