The LINK-BELT 4-bolt flange bearings of the 6600 series 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 carries 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 —as in PLB6839FR or PLB6851FR— corresponds to the size within the 6600 series, and the suffix FR indicates the housing and sealing configuration. Each code groups standardized dimensions of shaft diameter, bolt hole 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 of grain plants and industrial ventilation systems. The 4-bolt flange allows mounting onto sheet metal or profile structure, with the shaft exiting perpendicular to the support face, which simplifies alignment in equipment where access is limited.

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

If you need a 4-bolt flange bearing for your equipment, send us the code PLB6839FR, PLB6843FR or the one on your list by WhatsApp. We will quote it shortly and, if you are looking for a variant that does not appear, write to us with the model or measurements and we will indicate the corresponding option.
