The SEALMASTER PN-R series is a 4-bolt flange mounted bearing housing from the CRFS-PN line. It mounts rotating shafts to flat surfaces, delivering rigid support and alignment where a firm, easily replaceable mounting is required. You will find it in agricultural machinery, conveyors, and general industrial equipment.

Reading the code helps you identify the right unit. The PN portion denotes the 4-bolt flange housing family, while the number after it, as in PN-20R or PN-32R, corresponds to the mounted bearing size. The R suffix sets this variant apart within the CRFS-PN line. With that information, you can pinpoint the exact reference and ask about the size your application needs.

Typical uses include belt conveyors, elevators, mixers, milling equipment, and agricultural machinery. In food plants, cement plants, quarries, and agro-industrial facilities, the 4-bolt flange simplifies mounting on plates or structures and lets you replace the bearing without taking apart the whole assembly.

When selecting a housing, consider shaft diameter, load type, and operating environment. The mounted bearing's seal guards against dust and moisture; in dirty or frequently washed areas, check the seal type. Proper flange alignment and even tightening of the four bolts are essential to avoid stress and extend service life.

Flange mounted bearing units from different manufacturers can be interchangeable when flange dimensions, shaft diameter, and mounting style match.
