The SNH split housing from SKF is a housing split into two halves that simplifies bearing mounting and removal without disassembling the shaft. It is used to support rotating shafts in transmission equipment, with the advantage of being able to replace the bearing without moving the machine. MR Accesorios Industriales sells this line, with technical advice to choose the correct configuration.

The SNH designation is read as a series of split housings for bearings with a cylindrical or tapered bore. The base number, for example 507, 509 or 511, indicates the housing size and the shaft diameter for which it is intended. The suffixes that appear after the slash, such as /VZ2P3, describe sealing variants, mounting type and materials. In the examples SNH 507-606/VZ2P3 or SNH 513-611/VZ2P3, the hyphen separates two equivalent numberings of the same housing. The VZ suffix usually refers to double-lip seals, and P to the presence of end covers or caps. It is always advisable to verify the exact combination in the manufacturer's catalogue.

These housings are used in conveyors, belts, elevators, mills, mixers and process equipment where the shaft must be supported with alignment and protection against dust or moisture. In Argentina they are common in food, cement, mining and aggregate processing plants, where maintenance is done with the machine stopped for the shortest possible time. The split construction allows the top cover to be removed, the bearing to be extracted and reassembled without uncoupling the shaft or moving the structure. MR Accesorios Industriales supplies them for replacement and new projects.

To select the housing you must define the shaft diameter, the bearing type (for example, ball or spherical roller) and the sealing system according to the environment. Internal clearance and lubrication must be specified: in applications with moderate load and speed, grease is used, and in humid environments or with frequent washdowns, tighter sealing is advisable. Alignment between housings is critical to avoid parasitic loads; mounting on a rigid base and checking with a straightedge or laser is recommended. The tightness of the joining bolts also influences the final tightening.

Regarding equivalences, SKF SNH housings can be interchanged with other brands that use the same standardized designation, but not all suffixes match. The SN, SNH or SNV series from different manufacturers share main dimensions, although seals, covers and materials vary. Before replacing one housing with another brand, compare the housing diameter, the center height and the mounting type.
