The SONL split plummer block housing from SKF is a mounting component split into two halves that houses bearings with a tapered bore, such as those in the 222, 223 or 230 series. It is used in equipment where the bearing cannot be slid on from the end of the shaft, because it allows assembly around the shaft and the bearing already in position. MR Accesorios Industriales carries this SKF line with technical advice to choose the right size.

The SONL designation reads as a size code: the number that follows indicates the shaft diameter for which the housing is made. For example, SONL 217-517 corresponds to a 17/8 inch shaft, while SONL 230-530 is for 30/8 inches (or 3 inches). The hyphen separates the measurement in eighths of an inch, so the first number is the eighths and the second is the equivalent in inches. This nomenclature lets you quickly identify the housing you need without relying on external tables.

In Argentine industry, SONL split plummer block housings are seen in mineral conveyors, mills, mixers, centrifugal pumps and process equipment in chemical and food plants. Their advantage is that they allow the bearing to be replaced without disassembling the entire assembly: the two halves are separated, the bearing is removed and it is reassembled. That is why they are common in lines where downtime is critical, such as in the cement industry or in aggregate processing plants.

To select the housing, take into account the shaft diameter and the type of bearing you will house. The SONL is designed for bearings with a tapered bore and adapter sleeve, which facilitates mounting and adjustment of internal clearance. Check that the shaft surface is clean and free of burrs, and that the two halves of the housing close without forcing. Bearing lubrication is done through the built-in grease fitting, and it is important to align the housing well with the shaft to avoid unnecessary axial loads.

As for equivalences, SKF SONL split plummer block housings can be interchanged with similar lines from other brands, but always verify the mounting dimensions and load capacity. Not all series have the same tolerances or the same fastening system. If you need to replace an existing housing, the safest approach is to compare the complete part number and the main dimensions. At MR Accesorios Industriales we can help you with that comparison.

If you already have the part number of the housing you need, send it via WhatsApp to MR Accesorios Industriales and we'll quote you. We can also advise you if you are assembling new equipment or if you have doubts about compatibility with the bearing you will use. With more than 80 years in the business, we know the typical applications of each series and we give you a hand so you don't buy too much or too little.
