A 4-bolt flange housed unit from the SEALMASTER line pairs an insert bearing with a cast iron housing, giving you a bolt-on support point for a rotating shaft. The VF4B 200 series is the reference to look for when the mounting surface is flat and the shaft needs firm, straightforward fixing.

The code tells you what you are ordering. VF identifies the housing style, a 4-bolt flange. 4B covers the flange size and its configuration. 200 is the insert bearing series. From there, the shaft number and any suffix are appended, as in VF4B-220S and VF4B-232S, where S marks the insert seal type. Reading the number this way keeps you from ordering the wrong bore or the wrong sealing arrangement.

Typical duty includes belt conveyors, bucket elevators, mixers, mills and other process equipment in food, chemical and aggregate operations. The flange bolts to sheet metal or steel structure, and alignment stays simple because the insert absorbs the small misalignments that show up during installation. That combination of rigid fixing and easy replacement is why these units are common in plants handling bulk materials, oilseeds, meat and mining feed.

Selection comes down to three things: shaft diameter, the nature of the load (radial, axial or combined) and the surrounding conditions. The S seal is the choice when dust and moisture are present. On installation, check that the flange face sits flat, tighten the bolts in a cross pattern, and lubricate the insert to suit the operating conditions. Keeping the two units on a shaft aligned reduces stress and helps the bearing reach its expected service life.

4-bolt flange housed units that follow the same nomenclature and shaft diameter can be swapped between brands. When you ask for a quote, compare the full part number: shaft number, flange type and seal suffix. We can point you to the equivalent that matches your equipment dimensions so the existing mounting does not have to be modified.
