The SEALMASTER RFBA series 4-bolt flange bearing is a mounted bearing ready to be fastened with four bolts onto a flat surface. It is used to support shafts in equipment where the flange allows firm, centered front mounting. MR Accesorios Industriales supplies this line with the technical backing of more than 80 years in the industrial sector.

The RFBA designation identifies the series of four-bolt flange bearings. The numbers following the hyphen, as in RFBA-103, RFBA-104 or RFBA-110, indicate the size of the mounted bearing and therefore the shaft diameter each unit accepts. The higher the number, the larger the shaft capacity. The RFBA series is recognized by its square flange with four mounting holes and a central housing that holds the insert bearing.

These bearings are used in conveyors, belts, elevators, mixers, blowers and process equipment where the shaft must be perpendicular to the mounting surface. In food, beverage, packaging and material handling plants in Argentina, the four-bolt flange facilitates anchoring to walls, frames and sheet metal chassis. They also appear in old machines being reconditioned, because flange mounting is a widespread standard.

To choose the correct bearing, take into account shaft diameter, load type, rotation speed and environment. The flange must rest completely and the four bolts must be tightened evenly to avoid deformation. In applications with dust, water or washdown, an insert with suitable sealing is advisable. Lubrication and internal clearance of the insert bearing are part of the design; do not modify them. When mounting, align the shaft with the bearing and avoid impacts on the outer ring.

The SEALMASTER RFBA series is generally interchangeable with other four-bolt flange mounted bearings of similar dimensions and capacity. Equivalence between brands does not depend only on the part number: verify shaft diameter, hole pattern, center distance and insert type. If you need to replace an existing bearing, send us the part number stamped on the part or the flange dimensions and we will indicate the compatible alternative.
