MONTON Fluid Dynamic Bearing (FDB) which is suitable for high quality rotating parts such as fans,
motors, flywheels, and gyroscopes, etc. The innovative technology
is to process the inner diameter surface of the bearing and make
the grooves with special programs and special tooling. This kind of
sintered copper alloy bearing with herringbone groove and
recirculation groove on the outer diameter surface will generate
dynamic oil pressure when it is running at high speed. The
herringbone will gather lubricating oil concentrating and average
distributing naturally between shaft and bearing to keep a stable
rotation. It is called FDB, which is currently the most effective
among various fluid dynamic bearing in the world.
Fluid dynamic bearings (FDB bearing) are unique bearing types
especially designed for computers, communications, and consumer
electronics industries. It is commonly used in cooling fans for
servers and PCs.
In comparison with standard ball bearings and sleeve bearings used
in the past, fluid dynamic bearings have the advantage of lower
noise and steadier performance while operating. our fluid dynamic
bearings achieved better lifetime and vibration resistance .
Fluid Dynamic Bearing (FDB) is a product with micron-level and high
precision. It plays an indispensable and important role in the
global electronic, fan-motor and electric appliance markets where
products tend to be light, thin, short and small, and pursue for
high efficiency, high speed and high quality. Jialian-Tech insists
on technology innovation, implements quality assurance system,
concentrates on environmental protection and energy saving, and
executes standardized production management to provide the highest
quality bearings which can help customers upgrade their fans,
motors, flywheels and gyroscopes, etc. to the leading high end
product.
FDB bearing's life expectation is based on the result of high
temperature and high humidity test (temperature 80ºC, humidity
65%). L10 life factor can then be calculated according to the test
data. The environmental temperature of general product
manufacturing, which is 60ºC , can then be calculated approximately
100,000hrs.
Various types of fans, motors, flywheels, and gyroscopes, etc. have
different types and sizes of bearings that respond to the different
kinds of operations. As long as it is a directional rotating part,
all can use the precision sealed Fluid Dynamic Bearing (FDB) of
MONTON to improve the quality of your products and extend the
service life. Our FDB has a simple appearance, it doesn't need to
apply preload spring and it is easy to install and assemble. In
particular, ultra-high-speed fan motors are used in household
appliances, drones, servers, and precision instruments. It is more
effective to use our FDB to lower vibration and reduce noise. If
currently listed, specifications do not meet your products, the
newer size can be designed according to the customer's request when
there is a large demand. If you would like forward information
about your product, please contact with us.
Herringbone Groove Fluid Dynamic Bearing (FDB) can be used in Fan
and Motor market. It can also be used in many different marketing
fields, such as Optics motors, Servo motors, Spindle motors, Trail
motors, Axial flow fans, and Centrifugal flow fans and Blowers.
FDBs are especially important supporters of high-speed flywheels,
gear transmission systems, motors, gyroscopes, and other precision
rotating parts. FDB can promote the above rotating systems to a
quiet, long-life grade. They are the best partners of all rotating
parts, and they are the most outstanding new favorite of the
bearing industry in this high-speed generation.
Herringbone Groove Fluid Dynamic Bearing (FDB) has characteristics
of long-life, low vibration, low noise, high damping, and is
suitable for high rotation. It can be widely used in motors, fans,
flywheels, gyroscopes, and other markets. FDB is quite different
from traditional Sleeve/Cu-alloy/Cu-tube bearings, though there is
all similar shape. FDB uses a special formula include refined
copper alloy, by processes of forming with pressure, sintered in
high temperature, cleaning in supersonic, impregnating with
lubricant in a vacuum. It can accept more ring stress, be more
porous, and have more oil storage. The unique Herringbone Groove
and lubricant will generate a magical dynamic oil pressure when the
shaft is rotating to form a uniform cylindrical oil film. The
bearing generates uniform radial damping around the shaft. It will
concentrate the shaft to avoid metal friction and contact
effectively. This is an important function that other brand
bearings can't match.
In the era of 5G and 6G communications, PC/NB, game computers, and
servers with high data flow and high heat sources all require
high-speed cooling fans. High-speed hair dryers, instant hand
dryers, high-resolution aerial cameras, intelligent drones, and
precision gyroscopes all require ultra-high-speed and low-noise
motors. Ball bearings will encounter some bottlenecks including
expensive, high-frequency noise, short-life, friction and heating
from the shaft and the inner ring, etc. Once the above bearings of
goods switch to FDB, almost all troubles will be solved. The
high-level ones enjoy the following advantages: quietness,
long-lived, durability, and cost down. The lower ones can easily
upgrade, increase competitiveness and open up new markets.
The characteristics of FDBs, such as low noise, low vibration,
impact resistance, low power consumption, and long life, are also
applicable to other fields. FDBs are also used in fan motors of
servers and notebook PCs. Nidec is not only working to expand these
application areas; it is also striving to improve the original
functions of FDBs. For example, we have developed software that
simulates the motor behavior to shorten the design and development
period for thinner HDD spindle motors that have higher performance.
At the same time, we are also studying oil used for the FDBs, and
working to develop oil that satisfies the requirements of lower
friction and longer life.
