SAF split plummer (pillow) block housings have a two-piece, cast metal construction with inch dimensions. These housings have been developed to be the best choice for design, quality, robustness, and cost efficiency. SAF housings, when used with SKF bearings, seals and related components, provide a tailored solution to achieve maximum service life and reduce maintenance requirements for rotating equipment.
