The Rexnord 9000 series 4-bolt flange bracket is a mounted bearing ready to be fastened to sheet metal or structure with four bolts. It is used when a rotating shaft needs to be supported with firm alignment and limited space available, for example in conveyors, agitators or process equipment. MR Accesorios Industriales sells this Rexnord line in Buenos Aires, Argentina, and will quote the ZA code you need via WhatsApp.

The 9000 series designation is read in blocks: the letters ZA identify the 4-bolt flange bracket, the following four digits indicate the bearing size and the MMF suffix defines the sealing type and housing configuration. That is why the codes in this series share a family and change in size. If you have the complete code, send it as is: that way the part is identified without ambiguity.

These brackets appear in belt and screw conveyors, mixers, blowers, pumps, industrial washers and packaging lines. In food, chemical and water treatment plants they are chosen for the ease of mounting on sheet metal frames and for the possibility of replacing the bearing without disassembling the entire assembly. They are also used in material handling equipment and agricultural machinery.

To select correctly, look at the shaft diameter, the expected radial and axial load, and the type of sealing required by the environment. The MMF suffix defines protection against dust and moisture; in areas with frequent washing or heavy dirt, a tighter barrier is advisable. During mounting, rest the flange on a flat surface, tighten the four bolts in a cross pattern and check shaft alignment before lubricating. Poor alignment shortens bearing life.

Mounted brackets are interchanged between brands by shaft number, flange type and distance between holes, not by the commercial code. If the equipment carries another brand, compare those dimensions and ask us: we will indicate the compatible alternative from Rexnord or from another line we sell. The code does not need to match letter by letter; the mounting data is enough to find the replacement.
