LINK-BELT 6600 series 4-bolt flange bearings are mounted units that combine an insert bearing with a circular flange housing, designed to secure rotating shafts to flat structures. They are used when the shaft must sit perpendicular to the mounting surface and rigid fastening with four anchor points is required. MR Accesorios Industriales sells this line for industrial applications in Buenos Aires, Argentina.

The designation of these bearings is read in blocks: the prefix PLB identifies the 4-bolt flange family, the four-digit number that follows corresponds to the size within the 6600 series, and the FR suffix indicates the housing and sealing configuration. Each code groups standardized dimensions of shaft diameter, bolt spacing and mounting height. To choose the right one, send us the complete code or the shaft and flange measurements.

These bearings are used in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and process equipment in food, chemical and aggregate treatment plants. In Argentina you will find them in packaging lines, conveyor belts in grain plants and industrial ventilation systems. The 4-bolt flange allows mounting onto sheet metal or profile structures, with the shaft exiting perpendicular to the mounting face, which simplifies alignment in equipment where access is limited.

To select the bearing, check the shaft diameter, the flange bolt hole center distance and the radial load it must support. The FR sealing protects against dust and moisture, so it is advisable in environments with particles or frequent washdowns. During mounting, make sure the mounting surface is clean and flat, tighten the four bolts in a cross pattern and check that the shaft turns without strain. Lubrication must be renewed according to the duty cycle and the type of grease specified for the application.

When replacing a bearing, interchangeability between brands depends on the flange dimensions and shaft diameter matching. The LINK-BELT 6600 series has equivalents in other mounted bearing lines, but it is not advisable to rely on the code alone: you must compare drawings or measure the flange and the housing. MR Accesorios Industriales will indicate the compatible alternative if you send us the measurements or the original code.
