SKF Pillow block housing Series: SAF

SAF split pillow (plummer) block housings are popular SKF bearing housings with inch dimensions. Different housing variants and seal designs are available, making the use of tailored housings virtually unnecessary and enabling cost-effective bearing arrangements. SAF and housings are split pillow block housings consisting of a cap and base. SAF housings have two or four holes cast into the base for attachment bolts. SAF housings are available in two designs depending on the series. SAF housings in the 2(00) and 5(00) series follow the M5 design, while housings in the 3(00) and 6(00) series follow the A design.

The split plummer block housings are typically used with self-aligning ball bearings, spherical roller bearings or CARB toroidal roller bearings fitted on straight or stepped shafts; the bearings can be mounted on adapter or withdrawal sleeves or directly on cylindrical shaft seats.

SAF and housings are made of grey cast iron. For applications where extra strength is needed, SAF housings are also available in cast steel, designation SAFS. SAF housings are also available in ductile iron (spheroidal graphite cast iron), designation SAFD.
