Locating and non-locating bearing
positions
SED housings can be used for both the locat-
ing and non-locating bearing positions and are
supplied in two designs:
• Housings with the designation suffix F have
a bearing seat that matches the bearing

width. These housings should be used for
spherical roller bearings in the locating
position and CARB toroidal roller bearings in
the non-locating position.
• Housings with the designation suffix L have
a bearing seat that is wider than the bear-
ing. These housings should be used for
spherical roller bearings in the non-locating
position. The possible axial displacement of
the bearing is listed in the product tables
(parameter “s”).

Load carrying capacity
SED housings are intended for loads acting
perpendicularly toward the support surface
within an angle of ±55°. If loads acting in other
directions occur, contact the SKF application
engineering service.
