Rexnord ZA5000-72 pillow block housings are mounted units that combine an insert bearing with a cast-iron housing, designed to support rotating shafts in transmission equipment. They are used when the shaft needs rigid support and stable alignment, with built-in lubrication and protection against contaminants. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, and advises you on choosing the right variant according to diameter and locking method.

The designation of the ZA5000-72 series reads in blocks: the letters ZA identify the family of mounted housings, the first number 5 corresponds to the pillow block housing type, and the following digits indicate the nominal shaft diameter in inches or millimeters depending on the variant. The suffix MM72 defines the bearing-to-shaft locking system, which in this series is by adapter sleeve. Examples such as ZAS5035MM72, ZAS5040MM72 and ZAS5050MM72 show how the code changes with size: the higher the number, the larger the shaft diameter. The complete code identifies the unit unambiguously.

These housings are used in belt conveyors, bucket elevators, mills, mixers, pumps and industrial fans. In Argentina they are common in food, cement, mining and aggregate processing plants, where dust and moisture demand robust housings. The ZA5000-72 series accepts moderate radial and axial loads, and its pillow block design allows mounting on a flat bed with two bolts. MR Accesorios Industriales supplies them for replacement and new projects throughout the country.

To select the correct housing, take into account the shaft diameter, radial and axial load, and environmental conditions. The ZA5000-72 series comes with a labyrinth seal that retains grease and blocks contaminants; check that the seal is not damaged before mounting. Lubrication is done with general-purpose lithium grease and must be renewed according to the duty cycle. It is essential to align the housing with the shaft and set the bearing axial clearance to avoid overloads. Follow the manufacturer's instructions for mounting the adapter sleeve.

Regarding equivalents, Rexnord ZA5000-72 housings can be interchanged with units from other brands that share mounting dimensions and load capacity, such as the SY, FY or UCP series from different manufacturers. Interchangeability is not automatic: you must compare shaft diameter, bolt spacing, center height and locking type. If you need to replace an existing housing, send us the code stamped on the housing or the main dimensions and we will indicate the compatible alternative.
