When a shaft needs solid support on a wall, frame, or steel structure and a pillow block will not fit, a four-bolt flange bearing housing is the practical answer. The Rexnord ZBR line covers this need. MR Industrial Accessories LLC supplies these housings to maintenance and purchasing teams across the United States and Latin America, and can help you confirm the right variant.

Reading the part number is straightforward. Every designation begins with ZBR, followed by four digits that indicate series and size. The 2000 line includes ZBR2080MM, ZBR2085MM, ZBR2090MM, and ZBR2100MM; the ZBR9000 series includes ZBR9045MM, ZBR9050MM, ZBR9055MM, and ZBR9075MM. The MM suffix identifies the sealing and mounting configuration for this family. When requesting a quote, provide the full part number exactly as it appears on the drawing or machine.

You will find these housings on belt conveyors, bucket elevators, mixers, blowers, and continuous process lines. In food, cement, grain, and tannery plants, they handle dusty, humid, or frequently washed environments. The four-bolt flange lets you align the assembly on a machined face and manage moderate radial and axial loads, staying within the limits of the mounted bearing.

Selection depends on shaft diameter, load type, rotation speed, and operating environment. For wet or dusty conditions, review the sealing and radial shaft seal. In high-temperature areas, check lubrication and internal clearance. During installation, set the flange on a clean, flat surface, tighten the four bolts in a cross pattern, and verify shaft alignment before final torque. A flange that is not seated properly will reduce bearing life.

Housings from different brands can sometimes interchange by shaft number, flange type, and sealing configuration, but no universal equivalence exists. Two housings with the same diameter may differ in hole spacing, center height, or locking method, so always compare drawing to drawing. For imported equipment replacement, send the flange dimensions and shaft diameter.

MR Industrial Accessories LLC supplies the Rexnord line and manufactures split plummer block housings, roller chains, and sheaves.
