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 and our Flangette Series, the 4-bolt flanged bearing units have bearings that can be moved and aligned to better accomodate long shafts.
Standard housings from AST Bearings include both cast iron and thermoplastic materials and come with built-in grease nibs.
