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 ability to accommodate small misalignments and combined loads. MR Accesorios Industriales sells this line for industrial plants, workshops and maintenance operations 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 up to PN-211. The PN prefix identifies the SEALMASTER spherical roller insert family. There are no additional suffixes in this series: the numeric code is the direct reference for ordering the replacement part.

These inserts are mounted in split plummer block housings that are bolted to the structure, which makes replacement easier without fully disassembling the shaft. They are common in belt conveyors, bucket elevators, mills, mixers, pumps and industrial fans. In Argentina they are found in food processing, 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 bearings 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, moisture, washdowns). Lubrication should use good quality grease and be renewed according to the duty cycle. During mounting, make sure the housing is aligned and 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 outer diameter, width and type of sealing before replacing. If you need an alternative, at MR we can point you to the compatible option.
