The SEALMASTER PN-R series housing is a 4-bolt flange mounted bearing unit, part of the CRFS-PN line. It is used to secure rotating shafts to flat structures, providing rigid support and alignment in equipment where mounting must be firm and easy to replace. It is a common solution in agricultural machinery, conveyors and industrial equipment operating in Buenos Aires and the rest of the country.

The PN-R series designation is read in parts: PN identifies the family of 4-bolt flange housings, and the number that follows — as in PN-20R or PN-32R — indicates the size of the mounted bearing. The R suffix distinguishes this variant within the CRFS-PN line. With that information you can locate the exact reference and ask about the size you need.

These housings are used in belt conveyors, elevators, mixers, milling equipment and agricultural machinery. In Argentina they are common in food plants, cement plants, quarries and agro-industrial facilities, where the 4-bolt flange makes mounting onto plate or structure easier and allows the bearing to be replaced without disassembling the entire assembly.

To select the correct housing, take into account the shaft diameter, the load type and the environmental conditions. The sealing of the mounted bearing protects against dust and moisture; in environments with a lot of dirt or frequent washing, it is best to verify the seal type. Flange alignment and even tightening of the four bolts are key to avoiding stress and extending service life.

Flange mounted bearing units are interchangeable between manufacturers if the flange dimensions, shaft diameter and mounting type match. When requesting a quote, provide the complete part number — for example PN-20R — and the shaft dimensions; that way we can indicate the compatible alternative or the version that best suits your equipment.
