Flange mounted bearings are used when a shaft axis is perpendicular to the bearing mounting surface. Available in 2, 3, or 4-hole configurations, flange mounted bearings provide a method of accurate mounting fits and load support. 2-bolt flanged bearings have a diamond shaped flange with 2 mounting holes. Most 3-bolt flanged bearings have a circular mounting flange with three, equally spaced mounting holes. Other hole configurations, such as an offset pattern, are also available. 4-bolt flanged bearings have a square or round mounting flange with four mounting holes. Selection of the appropriate bearing can be accomplished with knowledge of the shaft size and radial and thrust load requirements. Bearing type choices for flange mounted bearings include ball bearing, needle roller bearing, plain bearing, and roller bearing.Below is a list of Mounted Unit Bearings design features and characteristics.
