The SEALMASTER CRFS-PN housing is a 4-bolt flange mounted bearing unit, designed to secure rotating shafts to flat structures with firm, aligned support. It is used in equipment where the flange allows the bearing to be mounted directly onto plates or frames, simplifying assembly and replacement. MR Accesorios Industriales carries this line as a brand, with options for different shaft sizes depending on the part number.

The CRFS-PN designation is read in blocks: CRFS identifies the family of 4-bolt flange housings, PN indicates the mounting type and the final number corresponds to the shaft size. For example, CRFS-PN20R and CRFS-PN32R cover two different sizes within the same series. The R suffix indicates a construction variant of the assembly. To choose the correct part number, have the shaft diameter and the mounting type on hand.

These housings are used in conveyors, belts, elevators, mixers and process equipment in food, chemical and bulk material plants. In Argentina they are common in the oilseed, meatpacking and aggregate processing industries, where the 4-bolt flange simplifies installation on metal structures. They also appear in older machines being reconditioned, because they allow the bearing to be replaced without modifying the existing frame.

To select correctly, verify that the flange matches the hole pattern in the structure and that the shaft diameter corresponds to the part number. Mounting requires a flat, clean surface, even tightening of the four bolts and alignment with the opposite shaft to avoid side loads. Lubrication and sealing of the mounted bearing define its service life: in dusty or humid environments, it is best to prioritize variants with better retention. Follow the manufacturer's instructions for tightening and start-up.

Regarding equivalences, 4-bolt flange mounted bearing units are interchangeable between brands by shaft number and flange type, but the holes and overall height do not always match. That is why it is best to compare drawings before replacing one brand with another. MR Accesorios Industriales can indicate the compatible alternative within the lines it carries, keeping SEALMASTER as the brand reference.
