ZAS pillow block housings from Rexnord hold mounted bearings and bolt to the machine frame, giving shafts a firm, well-aligned seat in power transmission drives. Their design includes lubrication and sealing, so dust and moisture stay out of the bearing. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America, and helps match the housing to your shaft and load.
Every ZAS reference starts with the series letters, and the digits that follow set the size. Among the sizes in this line are ZAS2311, ZAS2315, ZAS2400, ZAS3107, ZAS3111, ZAS3115, ZAS3203 and ZAS3207. Shaft diameter and load capacity differ from one reference to the next. Give us the full part number, or the shaft dimensions plus what the equipment does, and we will come back with the exact reference.
Typical installations include belt conveyors, bucket elevators, mills, mixers, pumps and industrial fans. Plants handling food, cement, mining and aggregates rely on them where dust, moisture and washdown are part of daily operation. Chemical process equipment and packaging lines also use them when a sturdy support that is simple to service is what the job calls for.
Selection comes down to three things: shaft diameter, radial and axial load, and the conditions around the equipment. Look at the sealing arrangement as well, since lip seal and labyrinth seal versions keep contaminants away from the bearing. Grease choice follows the duty cycle, whether lithium or a high-temperature product. At installation, line the housing up with the shaft and draw the fastening bolts down evenly so the housing does not distort.
ZAS housings can be swapped with pillow block mounted bearings from other makers that use the same series naming and shaft diameter. Before you commit, check center height, hole spacing and how the housing fastens. Send the original part number and we will point you to the compatible option in our catalog.
Beyond the housing itself, we can help with the seals, lubricants and mounting tools that go with the job. Send your ZAS part number by WhatsApp or email and our team will reply promptly with a quote.

Frequently asked questions
- What does the ZAS designation mean in Rexnord housings?
- ZAS is the series marking for these Rexnord pillow block housings. The digits after it indicate the size and shaft diameter, so ZAS2311 is one specific size within the line. Share the complete part number and we will quote that exact reference.
- How do I choose the right ZAS housing for my application?
- Start with the shaft diameter, then the radial and axial load, then the environment the equipment works in. Sealing type and lubrication also affect the choice. With those details we can identify the ZAS part number that fits, or simply quote the number you already have.
- Are ZAS housings interchangeable with other brands?
- In general, yes, as long as the other pillow block mounted bearing uses the same series naming and shaft diameter. Compare center height, hole spacing and fastening type before substituting. Send us the original part number and we will identify the compatible alternative.
