The SKF SNL split plummer block housing is a housing split into two halves that accommodates bearings with adapter sleeves. It is used to mount shafts in machine structures where the bearing must be supported and protected, and allows inspection or replacement of the bearing without disassembling the shaft. MR Accesorios Industriales carries this line for plants and factories in Argentina.

The designation SNL identifies the category of split plummer block housings; the number that follows indicates the size and the combination of bearing and adapter sleeve it accommodates. The suffix NM indicates that the housing is supplied with a built-in grease labyrinth, without a friction seal. Therefore, when reading a code such as SNL 522-619 NM, the letters and numbers are not interpreted in isolation: they refer to a shaft size and a specific bearing. If you have doubts, send us the complete code and we will verify it.

These housings are seen in conveyors, bucket elevators, mills, mixers, pumps and industrial fans. In Argentina they are common in food, cement, mining and aggregate processing plants, where the environment has dust, moisture or frequent washdowns. The split housing facilitates mounting on long shafts and allows in-line maintenance. They are also used in equipment where the shaft works under flexing and a support that absorbs small misalignments is needed.

To choose the housing, verify that the series number corresponds to the shaft diameter and the bearing you are going to mount. The NM sealing with grease labyrinth is suitable for environments with dust or water; if there is high speed or temperature, it is advisable to evaluate another type of seal. During assembly, rest both halves on a flat surface, align the shaft and tighten the bolts evenly. Lubricate according to the bearing and check the clearance after tightening.

SKF SNL housings are interchangeable with other brands that use the same designation and standardized dimensions, but always verify the shaft diameter, bearing type and sealing system before replacing. Not all number and suffix combinations are equivalent between manufacturers. If you need to replace an existing housing, send us the code engraved on the housing and a photo of the assembly.

At MR Accesorios Industriales we carry SKF SNL housings and have more than 80 years of experience in the field. If you already have the housing or bearing code, write to us via WhatsApp and we will provide a quote. We can also advise you on choosing the sealing and mounting accessories.
