SKF bearing housings – overview, selection and application recommendations

Take-up housings Fig. 8
Take-up housings († fig. 8) are typically used
to maintain the tension in conveyor belt appli-
cations and are mounted onto a guide frame.
The assortment of take-up housings is pro-
vided in table 2 on page 32.
Two-bearing housings
Two-bearing housings († fig. 9) have intrin-
sically aligned bearing seats. As a result, they
can accommodate rigid bearings, such as deep
groove ball bearings, angular contact ball
bearings and cylindrical roller bearings. Two-
bearing housings are typically used in applica-
tions with an overhanging load.
The assortment of two-bearing housings is
provided in table 2 on page 32.
Roller bearing units Fig. 9
Roller bearing units consist of a bearing, hous-
ing, lubricant and seals as well as a mech-
anism to lock the bearing inner ring onto the
shaft († fig. 10). These ready-to-mount
units are assembled, lubricated and sealed at
the factory for maximum service life. Bearing
units require very little maintenance. They are
also easy to install and replace. Once a unit is
bolted to its support surface, only the grub
(set) screws in the collar need to be tightened.
The assortment of roller bearing units is
provided in table 3 on page 33.
Application-specific housings
Application-specific housings have features
that enable them to be used in special operat-
ing conditions. The assortment of application-
specific housings is provided in table 4 on Fig. 10
page 34.
