Track rollers with
cylindrical or crowned
outer ring - type
LR
•
Series LR rollers
are also called CAM
ROLLERS, can be used
in the heavy loads
track or used as an
idler wheel. They
are widely used in
the particular application
that the friction
should be reduced.
• The outer
diameter surface of
rollers is shaped
to the crowned runner
surface with R500
(suffix U),
so make the stresses
well when rollers
working.
• Rollers
take the internal
structure design of
deep groove ball bearings
or double row angular
contact ball bearings
and have a particularly
thick-walled outer
ring, so the rollers
can accommodate higher
loads.
• Rollers
are made of the high-quality
bearing steel, processed
by heat treatment
and precision grind,
and are filled with
a long service life,
high -grade and multi-purposes
grease. Rollers take
the metal shield (suffix
KDD)
or rubble seal (suffix
NPP)
to prevent the dust.
YITONG also can provide
the rollers with concentric
or eccentric pivot.
Some types of the
rollers can be made
from the corrosion
resistance stainless
steel.

Characteristics of
the guide system that
series LR rollers
are applied :
1.
Low resistance, long
service life, widely-use
Being cam rollers
with crowned runner
surface R500, make
its stresses in well-distributed
between rollers and
track when working,
thus the stresses
centralization are
avoided, the friction
resistance are reduced
and the service life
of rollers have been
improved a lot. Most
of the double row
cam rollers can be
relubricated through
the filling hole on
the inner ring to
adapt the adverse
working conditions.
2. Easy installation
After rollers assembled
the concentric or
eccentric pivot, installation
can be made convenient.
To adjust the eccentric
one's eccentricity,
the rollers can get
the fitting preload.
3. Smooth
running, minimum error
Besides we produce
the series LR cam
rollers according
to the standard of
rolling bearings,
we also make the strict
control on the rotary
accuracy of outer
ring in order to meet
special working mode
that inner ring is
fixed while outer
ring running.
