The SONL split housing from SKF is a locating component for bearings with a tapered bore, designed to be mounted on shafts and to accommodate bearings of series 218 or 228, among others. Its two-piece construction makes mounting and dismounting easier without fully dismantling the shaft, which simplifies maintenance on industrial equipment. MR Accesorios Industriales supplies this line, with technical advice to select the right variant for the application.

The SONL designation is read in parts: SONL identifies the category of split housings for bearings with a tapered seat; the first number (218, 228) indicates the size of the bearing it accommodates; the second number separated by a hyphen (518, 528) corresponds to the housing series; and the suffix K followed by a digit (K7) indicates design variants, such as the fastening type or the seal material. For example, SONL 218-518 K7 accommodates a bearing of series 218, while SONL 228-528 K7 corresponds to series 228. Knowing these codes is key to ordering the correct replacement part.

These housings are used in equipment where the shaft must be supported precisely and allow some oscillation, such as belt conveyors, mills, mixers, centrifugal pumps and industrial fans. In Argentina, they are common in food, cement, mining and petrochemical plants, where robustness and ease of maintenance are critical. Their split design allows the bearing to be replaced without dismantling pulleys, couplings or other shaft components, reducing downtime.

To select the housing, check that the bearing to be mounted has a tapered bore and that its designation matches the one indicated in the SONL code. The K suffix defines the seal type: K7 usually includes double lip seals for dusty or humid environments. During mounting, ensure the alignment of the two halves and even tightening of the bolts; proper bearing lubrication and control of internal clearance extend service life. If the equipment operates with vibrations, consider additional fastening.

As for equivalents, other manufacturers offer split housings with similar dimensions, but they are not always directly interchangeable: check tolerances, seal type and bolt thread. The SKF SONL designation is a recognized reference, and alternatives with their own codes may be found on the local market. For replacements, the safest approach is to compare drawings or consult a specialist who can validate dimensional and functional compatibility before buying.
