The SKF SNH series is a split plummer block housing designed to simplify bearing installation and replacement without removing the shaft from the equipment. Used across conveyors, elevators, mills and mixers, these housings support rotating shafts in demanding industrial environments. MR Industrial Accessories LLC supplies this line with technical guidance to help you select the right configuration for your application.
The SNH designation encodes the housing size and shaft fit. The base number—such as 507, 509 or 511—indicates the nominal shaft diameter and housing dimensions. Suffixes after the slash, for example /VZ2P3, specify sealing arrangement, end cover options and material variants. In codes like SNH 507-606/VZ2P3, the hyphen connects two equivalent size references. The VZ suffix typically denotes double-lip seals, while P indicates the inclusion of end covers. Confirm the exact combination in the manufacturer catalog before ordering.
These split housings are well suited for equipment that demands minimal downtime during bearing replacement. The two-piece design lets technicians remove the top cap, extract the bearing and reassemble without uncoupling the shaft or moving the machine. Typical applications include belt conveyors, bucket elevators, crushers, mixers and other process machinery where alignment and protection from dust or moisture are essential. The split construction supports efficient maintenance in food processing, cement, mining and aggregate plants.
To select the correct SNH housing, start with the shaft diameter and the bearing type—ball or spherical roller. Then define the sealing system based on the operating environment. For moderate loads and speeds, grease lubrication is common; in wet or washdown areas, tighter sealing is recommended. Proper alignment between housings is critical to prevent parasitic loads. Mount on a rigid base and verify alignment with a straightedge or laser. Evenly tighten the joining bolts to maintain uniform clamping force.
SKF SNH housings may interchange with other brands that follow the same standardized designation, but suffixes do not always match. Series such as SN, SNH or SNV from different manufacturers share main dimensions, yet seals, covers and materials can differ. Before substituting, compare housing bore, center height and mounting pattern.

Frequently asked questions
- What does the VZ2P3 suffix indicate on an SKF SNH housing?
- The VZ2P3 suffix specifies a sealing and end cover configuration. VZ generally refers to double-lip seals, and P indicates end covers or plates. The exact meaning varies by size and manufacturer, so always verify with the full code in the technical data sheet.
- Can I use a different bearing than the original in an SNH housing?
- Yes, provided the bearing's outside diameter and width match the housing bore and width. SNH housings accept ball or spherical roller bearings depending on the series. Check load ratings and mounting type before making a substitution.
- How should split housings be aligned during installation?
- Place the housings on a rigid base and align them with a straightedge, laser or dial indicator. Proper alignment prevents parasitic loads and early wear. Tighten the cap bolts evenly and verify bearing clearance before startup.
