Brand we market
The Rexnord housing category groups different ways of mounting a bearing to a machine structure. The list includes mounted pillow block, flange and cartridge units, rather than a set of identical empty housings. This variety distinguishes it from the spherical roller bearing page, which concerns the bearing itself, and from the separate insert bearing unit line with its own references.

ZMC2012 and ZMC2015 are listed as mounted cartridge bearings. Do not confuse them with loose bearings because some of their numbers resemble other Rexnord references. The complete designation identifies the article to compare against the machine housing.
ZA2311 is listed as a mounted pillow block unit and ZEF2107 as a mounted flange unit. This comparison shows why the initial letters matter alongside the numbers. Check the fixings in the record or drawing; one example does not justify assigning a hole count to every series.
In conveyors, elevators and fans, the housing determines how the shaft support attaches to the structure. Show the mounting surface and surrounding space. Looking only along the shaft end may conceal whether the unit mounts on a base, on a wall or inside a cartridge seat.
When replacing an installed assembly, retain both housing and bearing references wherever visible. Two units accepting the same shaft size do not necessarily share centre height, fixing spacing or external shape. These differences affect shaft position relative to the structure.
Send the Rexnord designation, quantity and destination machine. Include shaft diameter, fixing dimensions and a sketch identifying the seating surface, supported by front, side and plate photographs. Specify whether the request concerns a mounted unit or a particular component. If the neighbouring support remains installed, show it too, so the two-support arrangement can be understood without assuming identical references.
The examples here are listed as mounted cartridge bearings. Establish the article scope from the complete reference.
Their fixings differ. Review the structure and installation dimensions as well as shaft diameter.
It shows how the unit is attached and allows comparison of distances that a front view can conceal.
