The ZA line from Rexnord consists of pillow block housings that hold and support rotating shafts in industrial machinery. They suit installations where the base must stay rigid so alignment is maintained under moderate radial and axial loading. MR Industrial Accessories LLC supplies these housings to customers throughout the United States and in several Latin American countries. If you already know the part number, send it over WhatsApp or email and the team will get back to you with a quote.
Reading the code is the quickest way to narrow down a replacement. The letters in a ZA part number point to the pillow block housing family, and the digits that follow tie back to bearing size and shaft diameter. Different combinations of size and configuration appear across the series, so the complete number is what allows the exact part for your machine to be pinned down.
These units turn up in food processing, cement, steel, paper, mining and aggregate operations, and in conveyors, elevators, mills, mixers and other process equipment. The pillow block format bolts to steel structures or concrete foundations, which keeps installation and changeout straightforward for plant maintenance crews.
Selection comes down to a few inputs: shaft diameter, the radial and axial loads involved, and the conditions around the equipment. Sealing deserves a close look as well, since standard units typically carry labyrinth or contact seals that keep dust and moisture out. Use the lubricant specified by the manufacturer, align the base properly at mounting so the bearing is not stressed, and add extra fastening where vibration is present.
Rexnord housings can be swapped with other brands of pillow block mounted bearings when the critical dimensions line up: shaft diameter, mounting hole spacing, height to center and mounting type. During quoting, an equivalent that fits your equipment can be suggested while preserving the expected function and service life, with no redesign of the machine required.
Send the housing part number on WhatsApp or email for a prompt quote. The team also helps with choosing the right part or a compatible alternative, and split plummer block housings can be manufactured to order when an application calls for it. Model number or shaft dimensions are enough to start.

Frequently asked questions
- How do I identify the Rexnord housing I need?
- Check the part number stamped on the housing or on the equipment plate. If it is not legible, measure the shaft diameter and the distance between the mounting holes, and the equivalent model can be identified from that data.
- Are Rexnord ZA housings compatible with other brands?
- In general they can be interchanged with other brands of pillow block mounted bearings when the critical dimensions match. An alternative that fits your equipment can be offered at the quoting stage.
- What lubrication do these housings need?
- Use the grease recommended by the manufacturer for mounted bearings. How often you relubricate depends on temperature, speed and contamination, so follow your plant's maintenance plan.
