The SEALMASTER CRFC-PN series housing is a 4-bolt flange mounted bearing unit, designed to secure rotating shafts to flat structures with high rigidity and precise alignment. It is used in equipment where axial and radial loads must be transmitted directly to the frame, such as conveyor belts, mixers, blowers and process machinery. MR Accesorios Industriales supplies this line as a brand and advises you on choosing the correct variant for your application.

The CRFC-PN designation is read in blocks: CRFC identifies the 4-bolt flange housing family with mounted bearing; PN indicates the mounting and sealing configuration specific to this series. The number that follows — as in the example CRFC-PN20R — corresponds to the nominal shaft diameter. The final letter R indicates a construction variant within the same family. With the complete part number you can ask us for the exact part or its compatible equivalent.

These housings are chosen in food and beverage, water treatment, cement, mining and material handling plants. In Argentina they appear in belt conveyors, bucket elevators, agitators, centrifugal pumps and industrial fans. The 4-bolt flange allows mounting on sheet metal or profile structures, with the shaft perpendicular to the mounting plane, and absorbs combined loads without the need for an additional support.

To select correctly, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. In applications with dust or humidity, check the sealing of the mounted bearing; in equipment with misalignment, prioritize mountings that allow some angular compensation. Installation requires that the support surface be flat and clean, and that the bolts be tightened in a cross pattern with the proper torque so as not to deform the flange.

Flange mounted bearings are available from different brands with their own nomenclatures. Interchangeability is not automatic: shaft diameter, hole spacing, flange diameter and sealing type must be compared. If you send us the original part number or the main dimensions, at MR Accesorios Industriales we will indicate the compatible alternative.
