Rexnord ZA F pillow blocks are 3000 series mounted bearing units designed to support rotating shafts in industrial equipment. They are used when a robust base is needed to secure the shaft to the frame and absorb moderate radial and axial loads. MR Accesorios Industriales offers this line as an official brand, with alternatives for different shaft sizes and mounting configurations.
The ZA F designation is read in parts: ZA identifies the pillow block family, F indicates the mounting configuration or housing type, and the four-digit numeric block —as in ZA3115F, ZA3203F or ZA3307F— encodes the size and construction variant within the 3000 series. The first digits are usually associated with shaft diameter and the remaining ones with mounting particularities. To choose the correct replacement, the complete code is the governing data.
These pillow blocks appear in belt and screw conveyors, mixers, mills, centrifugal pumps, fans and process lines in food, chemical and aggregate processing plants. In Argentina they are found in material handling equipment and in machines operating with horizontal shafts supported at several points. The pillow block base allows anchoring to the floor or a steel structure with bolts, facilitating alignment during assembly and replacement during maintenance.
To select, take into account the shaft diameter, load type —radial, axial or combined—, rotation speed and environmental conditions: dust, humidity or frequent washdowns. The pillow block sealing defines how much it protects the internal bearing; in dirty environments, reinforced protection is advisable. Mounting requires a flat, rigid base, even bolt tightening and shaft alignment with the drive equipment. Lubrication must follow the duty regime and the grease type indicated for the application.
Regarding equivalents, 3000 series pillow blocks can be cross-referenced with equivalent lines from other manufacturers, but interchangeability is not automatic: center heights, hole spacing, shaft diameters and mounting types vary. The only safe way to replace is to compare the complete code and the critical housing dimensions. If you cannot find the exact variant, write to us on WhatsApp with the code or model you need and we will indicate the compatible alternative.
MR Accesorios Industriales offers the Rexnord line of mounted pillow blocks for plants that need reliable spare parts. If your equipment carries a ZA3115F, ZA3208F or any other code in the series, send us the data on WhatsApp: we will quote you promptly and advise you on the option that best suits your mounting.
