Split plummer block housing SN

The split plummer block housing SN is a split housing used to mount bearings on shafts in industrial equipment. It opens into two halves, which facilitates mounting and dismounting without disassembling the shaft or the transmission. To select it, consider the shaft diameter, the bearing it will house, the type of base fastening, and the available space around the equipment. The SN line is used with spherical roller bearings, which accommodate misalignment from mounting and shaft deflection.

In the MR catalog there are 8 references of this line, all from SKF, including SN 3040. The SN designation identifies the series of split plummer block housings with a base with two anchor holes; the number that follows indicates the housing size and is related to the shaft diameter and compatible bearing. These housings are complemented by covers, seals, and retaining rings, which define the sealing and retention of the bearing within the housing.

Typical applications are equipment with drive shafts, conveyors, fans, pumps, mixers, and process machinery where the shaft is supported at multiple points. Because it is split, the housing allows replacing the bearing or inspecting the shaft without moving the entire machine, which is key in equipment with difficult access or with transmission assembled on the shaft.

To request a quote for a split plummer block housing SN, you need the complete part number, for example SN 3040, or the shaft diameter and the bearing you will mount. If you have the part number of an equivalent housing from another line, share it and we will cross-reference it with this series. It is also helpful to indicate the type of fastening and whether you need covers or seals, because they are quoted as part of the assembly.

Write to us via WhatsApp or email with the part number and measurements, and we will send you the quote. If the housing will be mounted with a bearing, also send the bearing reference to verify compatibility within the SN line.
