Bearings, Track rollers
with one beveling
profile - type RE
•
Journal Bearings are
used for the LINEAR
GUIDANCE system, in
which the track has
a " V "
profile groove with
an angle of 70 degrees.
.
• Journal
Bearings feature the
internal design of
high precision deep
groove ball bearings
and a thick-walled
outer ring, so bearings
can accommodate higher
load carrying capacity.
• Bearings
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. Bearings take
the metal shield (
ZZ ) or rubber seal
( 2RS ) to prevent
the dust. YITONG also
can provide the bearings
with concentric or
eccentric pivot.
Characteristics
of linear guidance
system that Journal
Bearings are applied
:
1.
High speed,
minimum noise level
Journal Bearings
take the internal
design of deep groove
ball bearings, and
the roughness of its
working surface is
fine, so the bearing
features low friction
resistance and swift
speed up in the short
time when running.
2.
Commonly uses,
easy installation
The bearings
can be enhanced their
commonly uses with
mounting various sizes
concentric pivot and
eccentric pivot having
different eccentricity,
and it is easy to
make the installation
and to adjust the
preload.
3.
Smooth and
accurate running,
long service life
YITONG special
manufacture equipments
of machine and inspection
facilities make accuracy
in the angle of bearings'
profile, so the bearing
and track can be matched
well. Mature manufacture
techniques and critical
inspection procedure
make all bearings
in the Kea (radial
runout) of outer ring
within 0.01mm, so
the guide system has
the characteristics
of long service life
and smooth running.
