P4 Abec7 3.175*6.35*2.38mm R144zz Medical Dental Handpiece Drill
The Dentist Dental Dental bearing is a special mobile phone
bearing. Company production of dental drill bearing inner and outer
rings through refining stainless steel (9Gr18) materials; ball by
refining stainless steel (9Gr18) or non-metal super hard Si3N4
materials with good wear resistance; holder has the advantages of
high strength, low friction with.
And a self lubrication performance of polyimide or 80 ~ 120
phenolic clamp cloth bakelite material, dental drill bearing in 200
~ 250Kpa air pressure, speed up to 350000 ~ 400000rPm. Under normal
condition, dental bearing working life for more than 6 months.
High speed dental cell phone bearing manufacturing accuracy in line
with the national standard P4 level GB/T307.1-94 tolerance, can be
applied to different types of dentists in the world.
With the development of medical technology, now the high-speed
dental drill mobile phone with more design, but each kind of design
include turbine, head, couplings, and a bit. In the turbine driven
by the drill bit can reach maximum speed of 450 thousand
revolutions per minute.
The drill bit is the most important part of the dental drill. It is
short and highly durable, able to withstand very high RPM as well
as the resulting high temperature. The air turbine engine is
sandwiched between 2 high speed bearings and is wrapped in a bit,
which is driven directly by a series of drive shafts and gears. The
key factor to achieve high speed dental drill bearing. Therefore,
the precision of the bearing, materials, structure, and the rolling
body, channel and maintain the material on dental drill bearing
performance has a direct impact. The supply of dental bearings are
important for any dental and dental mobile phone manufacturers a
1 true 450000 RPM high speed
Dedicated P4 / ABEC 7 precision
Stainless steel (440 C) and ceramic ferrule (silicon nitride) ball
Compound fiber reinforced phenolic retainer
If the drill bit can reach very high speed, can reduce the pain of
patients in the treatment of teeth. 45 thousand revolutions per
minute is internationally recognized dental drill bearing can reach
the highest speed can reach the requirement of bearing manufacturer
in the world did not several, and strong bearing force is really
one of them. In order to produce the highest quality of dental
drill bearing, we did a lot of tests and experiments, up to now we
have stable yield and quality bearings.
2 dedicated ABEC7 P4 bearing precision:
In addition to 450000 rpm, it is another important factor to
measure a bearing manufacturer's ability to achieve ABEC7 P4
bearing accuracy. Although many factories in their products marked
P4/ ABEC7 precision, but once you find the use of these bearings
can be easily them and not the degree of accuracy and the accuracy
grade of most of these counterfeit bearings only ABEC3. This is
part of the dental bearing special low price.
But the low quality of the dental bearing will greatly hurt the
drill and mobile phone equipment. According to statistics, more
than 60% of the bearing market is flooded with fake bearings. Due
to the limitation of materials and manufacturing technology, the
rigidity of these low end bearings can not meet the national
standard, which will shorten the service life of the instrument,
and cause damage to other parts. The gap between different ABEC
accuracy levels may also lead to assembly difficulties, or even
scrap the entire device. Intense bearing has become the country's
leading micro bearing manufacturers, and truly achieve the ABEC7 P4
level, and even individual models can reach ABEC9 P2.
3 stainless steel (440 C) and ceramic ferrule (silicon nitride)
These rings can drill bearing made of stainless steel (9Gr18), and
the rolling of the material is a silicon nitride ceramic ball. The
selection of high quality raw materials significantly improved the
durability of the bearing and speed, so as to ensure the overall
performance of the dental drill bearing.
4 composite fiber reinforced phenolic retainer:
100% focus on the details of each bearing product quality. Compound
fiber reinforced phenolic retainer has been treated by a rigorous
and complex chemical process. To ensure that the bearing can be
under the maximum 450 thousand speed of about 18 months of
operating life, and the whole process of the rotation is low noise,
low vibration. Because of the chemical oil immersed in a retainer,
so these dental bearing with self lubrication function good.
Mobile phone maintenance drill bearing
1 clean exterior surface of the nose.
2 insert drill chuck.
3 according to the following steps to clear the phone inside the
A. spray cleaning for 1 to 2 seconds.
B. use paper towels to wipe the nose of debris and debris.
C. repeat the above 2 steps until completely clean.
D. dry nose surface of the liquid.
E. repeat the action until the surface is completely dry.
4 according to the manufacturer's instructions with mobile phone
5 head cooling to room temperature.
6 drops of 2 drops of lubricating oil into the drive air pipe.
7 wipe off the excess oil.
8 wipe the outer surface.
9 now the drill can use mobile phone.
In order to guarantee high speed performance, dental bearing
loading unit should add a certain axial load. Users in the
installation and use should be careful operation and careful
installation and maintenance, in order to avoid damage to the ball
and channel, bearing pollution and improper lubrication will
directly affect the performance index and service life. Our dental
drill bearing products include: dental bearings, bearings for
dental, dental handpiece bearings, dental bearings, dental
handpiece Peilin, high-speed bearings, bearing phone bur bearing.
|1,It is best that the interference fit between bearing bore and
turbine shaft is under 0.5um～1.5um. When putting burbine shaft into
bearing bore,the pressure should be forced on the face of inner
ring to avoide the damage of rollway and balls|
|2,After fitting the bearing into tubine shaft they should be clear
and instilled special lubricant.(Ethanol must not be used )|
|3,After high steam sterilized the Dental High Speed Handpiece
should be jetted some lubricant into the air inlet before used and
so that bearing could be used longer time.|
|4,To keep operating stability,the proload spring stress of bearing
should be controlled under 1.2±0.2N.|
