The SEALMASTER RFBA series 4-bolt flange unit is a mounted bearing ready to be fastened onto a flat face, with the shaft passing through and the flange bolted in a cross pattern. It is used when the mounting requires firm frontal fastening and little axial space, for example on sheet metal walls, frames or gearboxes. MR Accesorios Industriales supplies this line and advises you on choosing the right size according to shaft diameter and load type.

The RFBA series designation is read in parts: the letters identify the 4-bolt flange unit family and the number that follows, expressed in millimeters, corresponds to the shaft diameter it accommodates. Thus, references such as RFBA-45MM, RFBA-50MM or RFBA-60MM cover shafts of 45, 50 and 60 mm respectively, and the series scales in 5 mm steps up to the largest sizes. The MM suffix confirms that the size is in the metric system, a key detail so as not to confuse it with inch lines.

In Argentine industry these units appear in belt conveyors, packaging lines, mixers, blowers and process lines where the bearing is mounted on a vertical or horizontal structure. They are also found in milling equipment, food plants and workshop assemblies that require a self-aligning and easily replaceable unit. Being a four-bolt flange, the bolt pattern distributes loads better than a two-bolt unit.

To select well, take into account the shaft diameter, the load type (radial, axial or combined) and the working environment. In areas with dust or humidity, it is best to prioritize the sealing of the mounted bearing; in applications with slight misalignment, the self-aligning capability of the unit helps compensate. When mounting, rest the flange on a flat, clean surface, tighten the bolts in a cross pattern and check shaft alignment before start-up.

As for equivalents, 4-bolt flange units are interchanged between brands by shaft diameter and by distance between holes, not by the commercial code. Therefore, if you need to replace an existing unit, the most practical approach is to provide the complete code and, if possible, the flange and shaft dimensions. MR Accesorios Industriales tells you the compatible alternative within the lines it supplies.

If you are looking for a size you do not see among the usual references, write to us on WhatsApp with the code or model you need. We will send you a quote shortly and tell you the compatible alternative for your application.
