Introduction
This catalogue covers SKF linear ball
bearings, linear plain bearings and
accessories, with which it is possible to
construct economic linear guides of
particularly simple design for a wide
variety of applications. In cases where, for
example, load conditions are such that
these bearings and units cannot be used,
other SKF linear guidance systems are
available. Should information regarding
these other systems be required, please
contact SKF. The necessary information
will be sent free of charge and without
obligation, and a technical proposal will
also be prepared if required. This new
"Linear Bearings" catalogue includes
linear ball bearings of Series 1 and 3 to
ISO 10285, also linear plain bearings of
the same dimensions. Series 1 comprises
the compact linear ball bearings LBBR as
well as linear plain bearings LPBR. The
linear ball bearings LBBR are, in addition
to the standard version, also available in a
corrosion resistant version. Series 1 is
complemented by a comprehensive
range of linear bearing units. In addition to
the single bearing units, with special shaft
seals, tandem, duo and quadro units are
now included in the range. Series 3
Product Overview
comprises the advanced cylindrical
design LBCR .. A and LBCT .. A linear ball
bearings as well as the self-aligning LBCD
.. A and LBCF .. A varieties. The range is
complemented by the LBHT .. A range of
linear ball bearings with extra high load
carrying capacity.
In order to keep abreast of ever increasing
user demands, SKF has fundamentally
revised its linear ball bearings of series
LBC (ISO series 3). The resultant new
linear ball bearings offer distinct advantages
over the former LBC series and the
linear ball bearings currently available in
the market. A particularly important fact is
that the new ISO series 3 bearings can
now also be supplied in a corrosionresistant
standard version. Moreover, their
integral double-lip seal permits ‘for-life’
lubrication under standardoperating
conditions.
As a matter of course, the new linear
ball bearings are interchangeable with the
former LBC series and all linear ball
bearings currently available.
Also forming part of this size range are
the LPAR and LPAT linear plain bearings
which appear for the first time in this
catalogue. All linear bearing units are
fitted as standard with self aligning linear
ball bearings to accommodate misalignment.
Other designs can be found in the
appropriate tables. The range of shaft
carriers has been extended to include a
shaft block conforming to the ISO
standard. Shafts, which constitute the
raceway of linear ball bearings and linear
plain bearings are naturally included in the
SKF range of shaft guides.
This catalogue is based on current
production. The right is reserved to make
changes necessitated by technical
developments of the products so that the
benefits can be passed on to the user
without delay. Information from previous
catalogs is superseded by the information
contained in this edition. In this catalogue
the units used are in accordance with the
international Sl system.
Conditions of delivery and payment
are generally based on those ruling at the
time of delivery.
Important notice SKF linear ball
bearings are coated with a corrosion
inhibiting preservative. Before mounting
the bearings, they should be
suitably lubricated. See also Publication
No. 4185E, SKF Linear guide
