SEALMASTER CRFS-PN series 4-bolt flange bearing units are mounted units that combine an insert bearing with a circular flange housing, designed to secure rotating shafts to a flat surface. They are used when the shaft runs perpendicular to the mounting plane and rigid support with four anchor points is required. MR Accesorios Industriales supplies this line as a brand for plants, workshops and process equipment in Buenos Aires, Argentina.

The CRFS-PN series designation is read in blocks: the letters CRFS identify the 4-bolt flange bearing unit family, and the PN suffix corresponds to the housing variant of this line. The number after the hyphen indicates the unit size within the series, as in CRFS-PN12, CRFS-PN16 or CRFS-PN24. That number is not a shaft diameter or a mounting dimension: it is the size code you need to provide so we can quote the correct unit.

These bearing units appear in belt and chain conveyors, mixers, fans, centrifugal pumps, packaging lines and aggregate processing equipment. In the Argentine market they are found in food, chemical and cement plants and in maintenance workshops replacing worn units on existing structures. The 4-bolt flange allows mounting on sheet metal or structural steel with a symmetrical bolt pattern, which is useful when the shaft must be precisely aligned with the drive machine.

To choose correctly, consider the shaft diameter and locking type, the sealing required for the environment (dust, washdown water or chips) and the intended lubrication. During mounting, seat the flange on a clean, flat surface, tighten the four bolts in a cross pattern and check shaft alignment before starting the machine. A misaligned unit shortens the life of the insert bearing and generates vibration throughout the assembly.

Flange mounted units are interchangeable between manufacturers by size number and housing dimensions: bolt circle diameter, number of holes and shaft diameter. When requesting a quote, it is best to provide the complete code of the old unit and, if possible, a photo of the housing and shaft. That way we can indicate the compatible alternative within the SEALMASTER line or the equivalent option that best suits your equipment.

If you need to replace a flange bearing unit or build a new machine, send the CRFS-PN code by WhatsApp to MR Accesorios Industriales. With the model and shaft dimensions we will quote the unit and indicate the compatible alternative. More than 80 years supporting Argentine industry from Buenos Aires.
