The SEALMASTER CRFS-PN housing is a 4-bolt flange mounted bearing, designed to fasten 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, making assembly and replacement easier. MR Accesorios Industriales sells this line, with alternatives for different shaft sizes depending on the part number.

The CRFS-PN designation is read in blocks: CRFS identifies the 4-bolt flange housing family, 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 suffix R indicates a construction variant of the assembly. To choose the correct part number, have the shaft diameter and 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 that are 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 determine 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.

As for equivalents, 4-bolt flange mounted bearings are interchanged 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 with the drawing in hand before replacing one brand with another. MR Accesorios Industriales can point you to the compatible alternative within the lines it sells, keeping SEALMASTER as the reference brand.
