The SEALMASTER PN Gold series mounted housing is a pillow block bearing unit designed to work in severe conditions, with reinforced sealing and corrosion-resistant materials. It is used to support rotating shafts in equipment where dust, humidity or frequent washdowns shorten the life of a standard housing. MR Accesorios Industriales supplies this line as a brand and helps you choose the correct variant for your application.

The PN Gold series designation is read in blocks: the initial letters indicate the housing type and its configuration, while the number that follows PN corresponds to the shaft diameter in inches. The RT suffix indicates a specific construction variant within the family, oriented to applications with particular sealing or mounting requirements. A concrete example is CRTBC-PN20RT, where 20 refers to the 20-inch shaft. To interpret other combinations, write to us with the complete part number and we will indicate the equivalent.

These housings are used in belt conveyors, bucket elevators, mixers, pumps and process equipment in food, chemical, paper and water treatment plants. In Argentina, they are common in sugar mills, meatpacking plants and animal feed plants, where pressure washing and humid environments demand sealing superior to that of a conventional housing. They also appear in mining and quarries, where abrasive dust is the main enemy of mounted bearings.

To select the correct housing, take into account the shaft diameter, the type of load — radial, axial or combined — and the environmental conditions. The PN Gold series prioritizes protection against contaminants: verify that the sealing is adequate for the level of dirt and humidity in your equipment. During installation, ensure a rigid and aligned base, and respect the tightening torque of the mounting bolts. Lubrication must be the one indicated by the manufacturer and renewed according to the duty cycle. Slight misalignment can be compensated with self-aligning housings, but it is best to correct it at the frame.

When replacing a mounted housing, interchangeability between brands depends on the mounting dimensions — hole spacing, height to shaft center and shaft diameter — more than on the commercial part number. Many equivalent series from different manufacturers share those dimensions, but not always the sealing system or load capacity. If your equipment has a SEALMASTER housing, the most direct option is to quote the same part number; if you are looking for an alternative, compare the mounting drawings first. MR Accesorios Industriales advises you to find the compatible option.
