Rexnord ZAS F housings are mounted bearing units from the 3000 series that support rotating shafts on a solid base. They bolt to beds or structures and allow the shaft to turn while the radial load is distributed through the housing. MR Industrial Accessories LLC supplies this line to plants and workshops across the United States and in several Latin American countries.

The code breaks down simply: ZAS identifies the pillow block housing with mounted bearing, and the final F denotes the housing configuration and locking method. The middle digits, as in ZAS3115F, ZAS3203F or ZAS3307F, set the size within the 3000 series. The first two digits group the bearing series, while the remaining ones distinguish shaft size and load capacity. To pick the right part number, have the shaft diameter and the mounting hole spacing ready.

These units are common in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and industrial fans. They appear in food processing, cement, quarrying, sugar and metalworking operations, where dust, humidity or frequent washdowns are normal. The cast housing and mounted bearing make assembly and replacement straightforward: the complete unit is swapped out without reworking the seat in the structure.

When selecting a ZAS F, match the sealing type to the environment. A clean area calls for different protection than one with water or particles. Also review the intended lubrication and how easily the unit can be relubricated, the bearing internal clearance, and alignment between housings. A base that is not level or uneven bolt tightening will shorten bearing life. Follow the manufacturer's instructions for mounting and tightening the locking screws.

Mounted bearing housings interchange between brands by shaft number, housing type and locking configuration. Rexnord, Link-Belt and other equivalent lines share dimensional criteria, but comparing part numbers alone is not enough. Check shaft diameter, center height, hole spacing and sealing type. If the original housing is no longer available, MR Industrial Accessories LLC can point you to a compatible alternative.

If a ZAS F is needed for a stopped machine, send the complete part number by WhatsApp or email, for example ZAS3207F or ZAS3308F, and the team will reply promptly with a quote. If the number is not at hand, send the shaft diameter and a photo of the mounted housing. MR Industrial Accessories LLC helps you find the unit that fits your application.
