Bearing type
Franke slim bearings of type LSB consist of a bearing element
type LEL with a ground raceway, embedded in two bearing
sleeves made of metal. The sleeve holds the bearing together
and hence permits rapid and simple assembly.
Characteristics
Slim bearings type LSB consist of two inner and outer race
rings with ground raceway, one plastic cage with retained
balls and a surrounding metal sleeve. The sleeves and the
race rings are separated; their diameter can therefore be
altered elastically for mounting. Unlike standard slim bearings,
Franke slim bearings type LSB can be modified in terms of
clearance/preload.
Mating structure
The greatest levels of accuracy are achieved if the constructive design of the mating parts takes place in such a way that
the handling of all diameters and surfaces relating to each
other can take place within in one setting. The running
accuracies indicated in the diagram are average values and
may be improved by restricting the tolerances (see 'Technical
information').

Please find construction examples, special forms, special
accuracies and other options of individual tailoring to your
applications and also instructions on assembly on pages
11 – 19.
Rotational resistance
The rotational resistance indicates the preload on the bearing
assembly. It is dependent on the respective type and the race
ring diameter. The values indicated in the diagram are
standard values and can be aligned individually.
