SONL Split Plummer Block Housing

The SONL split plummer block housing is a mounting component split into two halves that accommodates bearings with a tapered bore, such as those in series 222, 223 or 230. It is used when the bearing cannot slide on from the shaft end, because it allows assembly around the shaft and the already positioned bearing. To select it, consider the shaft diameter, the bearing you will mount, and the type of fastening; the housing is supplied in two halves that are bolted together and fastened to the structure.

The series shown in the catalog include SONL and SOFN. The SONL designation corresponds to a split plummer block housing with a base and mounting holes, designed for bearings with a tapered bore and adapter sleeve. The SOFN series is a variant with similar design characteristics, also for bearings with a tapered bore. Both are mounted with the corresponding covers and accessories to complete the assembly.

These housings are used in equipment where axial access is limited, such as conveyors, mills, mixers, pumps and industrial fans. They are also common in applications where the bearing must be replaced without disassembling the entire shaft, because the split design simplifies maintenance.

To request a quote for a SONL split plummer block housing, you need to provide the full part number (for example, SONL 234-534 or SOFN 536 BF), the shaft diameter, and the bearing you will mount. If you do not have the part number, we can help you identify it from the dimensions or the equivalence with other systems. MR Accesorios Industriales offers 26 SKF SONL housing references, with service from Buenos Aires, Argentina.

The housing is supplied with the two halves and the joining bolts; the covers and locating rings are ordered separately according to the bearing. It is important to verify compatibility between the housing, the bearing and the adapter sleeve before assembling the unit.
