SAF and SAW split pillow blocks use a two-piece, cast metal housing with inch dimensions. With the included SKF bearings, seals, and related components, they provide a tailored solution to achieve maximum service life and reduce maintenance requirements for rotating equipment. These pillow blocks have been developed to be the best choice for design, quality, robustness, and cost efficiency.
