The SEALMASTER PN series insert bearing is a spherical roller bearing with an extended inner ring, designed to be mounted in split plummer block housings and split housings. It is used in equipment where the shaft must be supported with the possibility of small misalignments and combined loads. MR Accesorios Industriales sells this line for industrial plants, workshops and maintenance in Buenos Aires, Argentina.

The PN series designation reads as a size code: the final numbers indicate the shaft diameter for which the insert is made. For example, PN-204 corresponds to a 20 mm shaft, PN-205 to 25 mm, PN-206 to 30 mm, and so on according to the code. The PN prefix identifies the SEALMASTER family of spherical roller inserts. There are no additional suffixes in this series: the numeric code is the direct reference for ordering the replacement.

These inserts are mounted in split plummer block housings that are bolted to the structure, which makes replacement easier without dismantling the entire shaft. They are common in belt conveyors, bucket elevators, mills, mixers, pumps and industrial fans. In Argentina they are found in food, cement, mining and agro-industrial plants, where fast maintenance and resistance to contamination are key.

To select the correct insert, take into account the shaft diameter and the type of load: spherical roller inserts withstand moderate radial and axial loads, and tolerate small angular misalignments. Sealing is essential: check that the insert has seals suitable for the environment (dust, humidity, washdowns). Lubrication must be with good quality grease and renewed according to the duty cycle. During mounting, make sure the housing is aligned and that the locking screws are tightened evenly.

As for equivalents, SEALMASTER PN inserts can be interchanged with other brands that use the same numeric nomenclature for shaft diameters, such as SKF, FAG or NTN, as long as the housing dimensions and the locking system match. It is important to verify the outside diameter, width and type of sealing before replacing. If you need an alternative, at MR we will indicate the compatible option.
