Linear bearing units with LBBR linear bearings or
LPB linear plain bearings
Linear bearing units incorporating
bearings of ISO series 1 are available
for unsupported applications in
closed design.
These cost-effective bearing units
are extremely space-saving thanks to
the compactness of the design, but
they can nevertheless accommodate
loads exceeding 25 000 N (e.g.
LQBR 50-2LS; see also page 13).
The new double lip seals fitted to
the LBBR bearings enable these
units to run without relubrication,
under normal operating conditions.
On special request, it is possible to
buy pre-greased bearings. This
guarantees that the right amount
of grease is inserted and that the
grease is properly distributed in the
bearing.
The systems are available in the
length required by the customer. See
also the chapter „Precision shafts“,
page 46 ff. Please note that the
maximum permissible angular misalignment
is 15 minutes of arc. For
the influence on the load carrying
capacity, see diagram 9 on page 18
in the technical handbook.
A corrosion resistant alternative
consists of aluminium housings with
stainless steel linear ball bearings
such as LBBR 20-2LS/HV6 or aluminium
housings fitted with plain
bearings.
For such applications the shafts
are made of stainless steel, normally
X90 CrMoV18.
