R8 Full Ceramic ZrO2 Ball Bearing 1/2"x 1-1/8"x 5/16" Zirconia Oxide
Full ceramic
bearing
with
diamagnetic
electrically insulating
,
wear resistance and corrosion resistance
,
not
self lubricating
,
high temperature resistance,
cold
and other characteristics,
can be used in
extremely
harsh environment
and
special conditions
.
The ferrule and the
rolling
body adopts
zirconium oxide
(
ZrO2
)
ceramic
materials
,
the retainer
using polytetrafluoroethylene
(
PTFE
)
as standard equipment
1.
high speed
:
with
cold resistance
,
stress
resistance to
pressure
,
small elastic
,
thermal conductivity
,
light weight
,
the advantages of small friction coefficient
,
can be applied to
12000 rpm
to 75000
rpm
for high speed
spindle and other
high precision
equipment
;
2.
high temperature resistant
:
use the temperature at 100
degrees to 600 degrees
between the
generated
due to the range of temperature
expansion
.
Can be used in
furnaces
,
plastic,
steel
and other
high temperature
equipment
;
3.
corrosion resistance
:
the material itself has
corrosion resistance characteristics
,
can be used
in strong acid
,
strong alkali
,
inorganic
,
organic salt
,
water
and other fields,
such as: plating equipment
,
electronic
equipment
,
chemical machinery
,
shipbuilding
,
and other medical equipment
.
4.
because of no
magnetic
,
magnetic
dust absorption
,
can reduce
premature bearing
flaking
,
big noise
.
Available
in the
demagnetization
device
.
Precision instruments and other fields
.
5.
due to electrical
resistance
,
electrical insulation
,
can avoid
arc damage
bearings
,
can be used in a variety of
insulation
of power equipment
.
6.
because of
the unique
ceramic
materials
,
vacuum
oil-free
self-lubricating property
,
in ultra-high vacuum environment
,
zirconia ceramic
bearings can
overcome the
plain bearing
can not realize
the problems of lubrication
.
Main uses
:
Medical equipment
,
optical instruments
,
printing machinery
,
machine tools,
high-speed motor
,
low temperature engineering
,
food processing machinery
