Split pillow blocks SAF and SAW series

Standard housing design Fig. 1

SAF and SAW housings are split pillow (plum-
mer) block housings consisting of a cap and
base. SAF housings have two or four holes cast
into the base for attachment bolts. SAW hous-
ings have four cast holes.
SAF housings are available in two designs
depending on the series. The designs share the
same dimensions. SAF housings in the 2(00)
and 5(00) series follow the M5 design († fig. 1),
while housings in the 3(00) and 6(00) series
follow the A design († fig. 2).
SAF and SAW († fig. 3) housings share the
same external dimensions, except for the width
of a few SAW sizes. These housings are wider
to accommodate wider 32 series bearings or
to accomodate the larger axial displacement
of bearings in the 22 series. Fig. 2
