When a rotating shaft needs solid support but the frame leaves little room, the Rexnord 9000 series 4-bolt flange bracket does the job: it bolts directly onto sheet metal or structural steel through four holes. Typical installations include conveyors, agitators and process equipment. MR Industrial Accessories supplies this Rexnord line and quotes the ZA code you specify through WhatsApp or email.

Read the code in three blocks. ZA tells you it is a 4-bolt flange bracket of the 9000 series; the next four digits set the bearing size; the MMF suffix covers sealing type and housing layout. Every code in the family follows that pattern, so only the size digits change from one part to the next. Send the full code exactly as printed and there is no room for confusion.

You will find these brackets on belt and screw conveyors, mixers, blowers, pumps, industrial washers and packaging lines. Food, chemical and water treatment plants often pick them because they mount easily on sheet metal frames and let maintenance crews swap the bearing without tearing down the whole assembly. Material handling equipment and agricultural machinery use them as well.

Selection comes down to three inputs: shaft diameter, the radial and axial loads you expect, and the sealing the environment demands. The MMF suffix sets the level of protection against dust and moisture, so a washdown area or a dirty floor calls for a tighter barrier. At mounting, seat the flange on a flat surface, torque the four bolts in a cross pattern, verify shaft alignment, then lubricate. Misalignment is what shortens bearing life.

Interchange between brands works on shaft number, flange type and hole spacing, never on the commercial code. If the machine currently runs another brand, measure those three dimensions and send them over; we will point you to the matching option from Rexnord or from another line we carry. The letters do not have to line up, the mounting data is what identifies the replacement.

Send the ZA code from the nameplate or from the bracket you are replacing, and our team will quote it promptly. If you need a variant you cannot find, message us with the model and we will tell you how to proceed. We also suggest equivalents and help you choose when the original reference is unclear.
