A flange bearing is a mounted unit whose housing bolts to a vertical face or panel instead of a flat base.
What is a bearing with flanges?
A flange bearing (or flanged unit) is an insert locked in a housing with a bolt-on face. The shaft runs through the insert; the flange takes the load into the machine wall. USA Bearings groups 2-bolt and 4-bolt patterns here so you can browse by bolt count and bore.
What are the different types of flange bearings?
The common industrial types are 2-bolt oval or diamond flanges, 4-bolt square flanges, and round cartridge flanges (UCFC). 2-bolt units fit tight frames. 4-bolt units spread load. Round cartridges fit circular cutouts. Pick the bolt pattern that matches the existing holes before you pick the bore.

What are the applications of flange bearings?
Flange units show up on conveyors, fans, agricultural implements, and any shaft that mounts through a panel instead of sitting on a base. If the shaft sits on a horizontal pad, you want a pillow block, not a flange.
When should I use a 2-bolt flange instead of a 4-bolt?
Use 2-bolt when the frame only has two holes or space is tight. Use 4-bolt when the load is higher or the original housing was square. Do not force a 2-bolt unit into a 4-bolt hole pattern.
