what is a four bolt flange bearing?
May 07, 2025
Four bolt flange bearings are mounted within a flanged housing and are preferred to shaft access when the bearing mounting surface is perpendicular. 4 bolt flanged ball bearing units have a square shape with four holes for mounting. The four hole design can bear higher loads than a two or three bolt flange.
Winstar Bearing can offer a variety of 4 bolt flange bearing units in a wide range of styles and sizes.
