Split pillow blocks SDAF series including the extended range (inch dimensions)

Standard housing design Fig. 1

All SDAF housings, which include the extended
range, are split pillow (plummer) block hous-
ings consisting of a cap and base († fig. 1).
Their robust design can accommodate shock
loads and heavy loads from any direction. All
SDAF housings have four holes in the base for
attachment bolts and tapped holes in their
caps for eye bolts.

Features and benefits
All SDAF housings share the following features
and benefits:
Stiff housing
The caps and bases are reinforced with extra
material († fig. 2). This improves heat flow Fig. 2
away from the bearing outer ring and avoids
distortion of the housing bore.
Caps and bases individually marked
The housing base and cap of all SDAF housings
are matched during manufacture and are not
interchangeable with the caps and bases of
other housings. To help avoid mismatch, each
cap and base are numbered († fig. 3).
