SKF

SAF and SAW Series (Inch Dimensions)

The SAF and SAW series are SKF’s standard inch-dimension split pillow block housings. SAF housings accommodate self-aligning ball bearings and spherical roller bearings with cylindrical bores or mounted on adapter sleeves for narrower bearing series. SAW housings are wider, designed primarily for bearings mounted on adapter sleeves in larger width series. Both types are cast from high-strength grey iron, with a two-piece cap and base, deep lubrication cavities, and machined surfaces for labyrinth or lip seals. These housings are found on belt conveyor pulleys, mine fans, hammer mills, and crushers throughout North America and in globally sourced equipment. The robust split design allows bearing replacement without removing the shaft, and the standardised bolt pattern ensures easy retrofitting. SKF’s precision-machined bore seats ensure proper bearing alignment, preventing induced loads that reduce bearing life.
