Rexnord ZA MMF pillow blocks are foot-mounted units designed to house mounted bearings in applications where the drive works with radial load and requires rigid, aligned support. They are used in process, conveying and material handling equipment, and allow replacing the complete assembly without machining the frame. MR Accesorios Industriales sells this brand and advises you to choose the correct variant according to the shaft and mounting type.
The designation of these pillow blocks is read in blocks: the initial letters identify the pillow block family, the number that follows marks the size within the series and the MMF suffixes define the housing and sealing configuration. That is why references such as ZA2050MMF72, ZA2060MMF72 or ZA2080MMF72 coexist: they share the unit type and change the size. The 5000 series and the SHURLOK line appear in the same family with other locking and mounting variants.
In Argentine industry these pillow blocks appear in belt conveyors, bucket elevators, mixers, mills, pumps and plant equipment. They are chosen when the shaft needs a pillow block with good rigidity and some self-aligning capability, and when standardizing replacement on lines with several support points is sought. They are common in food, cement, mining, chemical and aggregate processing, where the environment usually has dust, humidity or frequent washdown.
To select correctly, you must look at the shaft diameter and configuration, the type of locking onto the shaft, the sealing required according to the environment and the intended lubrication. During assembly, it is advisable to verify the alignment of the pillow block with the shaft, the tightening of the anchor bolts and the condition of the support surface. Adequate sealing and correct lubrication extend the life of the assembly and reduce unplanned downtime.
Among brands, mounted pillow blocks are interchanged by size number and unit type, but tolerances, seals and shaft locking systems change. That is why it is advisable to compare the complete designation and not just the diameter. If you need to replace existing equipment, send us the part number on the part or the equipment model via WhatsApp and we'll indicate the compatible alternative or quote it to measure.
