SNL Split Plummer Block Housings

The SNL split plummer block housing is a cast-iron housing split into two halves used for mounting bearings on rotating shafts. The advantage of split construction is that the bearing mounts and removes without disassembling the shaft or transmission. Selection depends on shaft diameter, bearing type and size, mounting position, and load and environmental conditions.

In SKF part numbers like SNL 205, SNL 207 or SNL 210, the SNL designation identifies the series and the number corresponds to the size of the housing, not the shaft diameter. In codes with two numbers, such as SNL 206-305 or SNL 208-307, both indicate bearing sizes that share the same outside diameter and fit in that housing. The complete part number, with its suffixes, is what defines the exact piece.

These housings are used in power transmission equipment, conveyors, process machinery, fans, pumps, and lifting systems. Because they are split, they allow inspecting or replacing the bearing in the field and reduce downtime. They are combined with closing caps, seals, and retaining rings to protect the bearing from dust, moisture, and lubricant loss according to the equipment's environment.

We sell SKF in this category. To request a quote, send via WhatsApp the part number engraved on the piece, the quantity, and any accessories you need. If you don't have the part number, provide the shaft diameter, the bearing it accommodates, and a photo or sketch of the assembly, and we'll indicate the SNL reference that applies.
