The LINK-BELT flange bearing of the PKB FH line is a four-bolt mounted unit that combines an insert bearing with a cast iron housing to secure rotating shafts directly onto flat structures. It is used in equipment where the shaft must sit perpendicular to the mounting surface and the load acts radially. MR Accesorios Industriales carries this brand and advises you on choosing the right size according to shaft diameter and load type.

The designation of these bearings is read in blocks. The letters PKB identify the four-bolt flange family; the number that follows, as in PKB22631FH, PKB22639FH or PKB22655FH, refers to the B22600 series and the size of the insert bearing. The FH suffix defines the housing and sealing variant. The examples PKB22643FH and PKB22663FH show how the code changes as the shaft size increases. The complete code unambiguously identifies the unit you need.

These bearings appear in belt and chain conveyors, bucket elevators, mixers, screens and process equipment in food, chemical and aggregate plants. In Argentina they are found in sugar mills, meatpacking plants, water treatment plants and packaging lines, where the four-bolt flange allows mounting onto sheet metal or profile without machining a housing. They are also used in fans and horizontal-shaft centrifugal pumps.

To select correctly, start from the shaft diameter and confirm that the flange has a bolt hole spacing compatible with your structure. Check the sealing: in dusty or wet environments, a variant with a reinforced seal is advisable. The insert bearing has normal internal clearance and is lubricated with general-purpose grease; during mounting, seat the flange flat, tighten the four bolts in a cross pattern and verify shaft alignment before starting up.

Flange mounted units are available from several brands with their own nomenclatures. Interchangeability is defined by shaft dimensions, flange bolt hole spacing and housing outer diameter, not by the code. If your equipment carries another brand, send us those data and we will indicate the compatible LINK-BELT alternative or the one that best suits your application.

If you already have the bearing code, send it by WhatsApp to MR Accesorios Industriales and we will quote it shortly. If you cannot find it, send a photo of the nameplate or the shaft and flange measurements: with that we identify the unit and give you the corresponding option. We can also evaluate sealing or material variants according to the working environment.
