The Rexnord ZA5000-72 series is a pillow block housing designed to support rotating shafts in industrial transmission equipment. It combines an insert bearing with a cast-iron housing, providing stable alignment and protection against contaminants. MR Industrial Accessories LLC supplies these units to customers across the United States, Canada, Mexico and South America, and can help you select the right variant for your shaft diameter and mounting requirements.

When reading the part number, the prefix ZA identifies the mounted housing family, the first digit indicates the pillow block type, and the following numbers specify the nominal shaft diameter. The MM72 suffix denotes the adapter sleeve fixing method. As the numeric portion increases, so does the shaft size—for example, ZAS5035MM72, ZAS5040MM72 and ZAS5050MM72 correspond to progressively larger diameters.

These housings are commonly found in belt conveyors, bucket elevators, mills, mixers, pumps and industrial fans. Their pillow block configuration allows mounting on a flat surface with two bolts, and they accommodate moderate radial and axial loads. Industries such as food processing, cement, mining and aggregate handling often choose this series for its robust construction in dusty or humid environments.

Before ordering, confirm the shaft diameter, expected loads and operating conditions. The ZA5000-72 series includes a labyrinth seal to retain grease and keep out debris; inspect the seal before installation. Use general-purpose lithium grease and follow a maintenance schedule based on duty cycle. Proper alignment between the housing and shaft is critical, and the adapter sleeve must be set according to the manufacturer's instructions to avoid premature wear.

If you are replacing an existing unit, compare mounting dimensions and load capacity rather than assuming interchangeability. Series such as SY, FY or UCP from other manufacturers may match, but verify shaft size, bolt spacing, center height and fixing method. Send us the code stamped on your current housing or the main dimensions, and we will suggest a compatible option.
