Linear ball bearings (fig. 5, 6 and 7) are
bushings with recirculating ball tracks
which provide low friction movement and
the possibility of unlimited stroke. With the
range of linear ball bearings, plain bearings
and accessories, it is possible to design and
build economical and simple linear guidance
systems to suit a wide range of applications.
The bearings are available in two size
ranges: the compact ISO 1 series and the
heavy duty standard ISO 3 series (table 2).
N.B.:
SKF linear ball bearings and units for
shaft diameter 6 mm and greater are
factory prelubricated by default 1) .
1) linear ball bearings without factory pre-lubrication
and preservative only can be ordered by using the suffix
“/VT808”, e.g. LBCR 20 A-2LS/VT808.
