Non-split plummer block housings and take-up housings SBD and THD series

Standard housing design Fig. 1

SBD plummer (pillow) block housings and THD
take-up housings are non-split housings. They
consist of a housing body and two covers. The
covers are bolted to the body with six or eight
bolts. SBD and THD housings are supplied
with different covers depending on the shaft-
bearing combination († page 493).
SBD housings are available in two designs
(† fig. 1), depending on the housing size. The
main difference is the holes for the attachment
bolts: one design has cast oblong holes, the
other has drilled holes. Other design differ-
ences include the overall shape of the housing
and the thickness of the reinforcement ribs.
THD housings have a special take-up SBD, design 1
design to maintain tension on a conveyor belt
(† fig. 2). SKF does not supply the frames.
