SKF SAF220 Split Pillow Block Bearing Housing

SKF SAF220 split pillow block bearing housing is a two-piece, four-bolt-base cast-iron housing from SKF's SAF family, designed to carry self-aligning bearings with a straight bore. The split design enables bearing installation, inspection, and seal service without removing the shaft, while the four mounting bolts provide a rigid, stable base to a machine bed. This SAF‑220 model is compatible with standard straight-bore spherical roller and self-aligning ball bearings used in split-housing configurations and uses an LER ring seal arrangement to help seal the shaft and retain lubrication. With its cast-iron construction, the housing offers strength and vibration damping for reliable operation in conveyors, fans, pumps, and other industrial drives where easy maintenance and durable shaft support are required. The four-bolt base variant is intended for applications demanding secure mounting and straightforward maintenance, and, when paired with the appropriate bearing insert and accessories, provides a serviceable, long-life bearing housing suitable for retrofit or new equipment alike.
