The SKF SONL split plummer block housing is a two-piece mounting component designed to hold bearings with a tapered bore, including those in the 222, 223, or 230 series. It is used when the bearing cannot be slid onto the shaft from the end, as it can be assembled around the shaft and bearing already in position. MR Industrial Accessories supplies this SKF line and offers technical guidance to help you select the correct size.

The SONL code indicates the shaft diameter. The number after SONL gives the size in eighths of an inch. For instance, SONL 217-517 fits a 17/8 inch shaft, while SONL 230-530 is for a 30/8 inch (or 3 inch) shaft. The hyphen separates the measurement in eighths from the inch equivalent. This naming system allows quick identification without external tables.

SONL split plummer block housings are common in mineral conveyors, mills, mixers, centrifugal pumps, and process equipment in chemical and food plants. Their key benefit is that the bearing can be replaced without dismantling the entire assembly: the two halves are separated, the bearing is removed, and the housing is reassembled. This makes them ideal for lines where downtime is critical, such as in cement or aggregate processing.

When selecting a housing, consider the shaft diameter and the bearing type. The SONL is intended for bearings with a tapered bore and adapter sleeve, which simplifies mounting and internal clearance adjustment. Ensure the shaft surface is clean and free of burrs, and that the two halves close without force. Lubrication is done through the built-in grease fitting, and proper alignment with the shaft is important to avoid unnecessary axial loads.

SKF SONL housings can be interchanged with similar lines from other brands, but always verify mounting dimensions and load capacity. Tolerances and fastening systems may vary between series. For replacement, compare the complete part number and main dimensions. We can assist with that comparison.
