What is a 2-bolt flange bearing unit?
It is a mounted insert in a two-hole flange housing. USA Bearings lists steel, stainless, pressed-steel, and thermoplastic 2-bolt units so you can match bore and housing material, then order singles or a commercial quantity.
How do I match a replacement 2-bolt flange?
Confirm shaft diameter, the center-to-center distance between the two bolt holes, and whether the insert uses set screws or an eccentric locking collar. Photos of the old unit help when numbers are worn off.
2-bolt vs 4-bolt flange — which do I need?
If the machine has two mounting holes in a diamond or oval pattern, stay on this 2-bolt hub. If it has four holes in a square, use the 4-bolt flange units page. Mixing them will not line up.
