What is small bearing?
Miniature and small-sized ball bearing mean
ball bearing, up to 30mm in external diameter
.
Miniature and small bearings
are used for extremely high speeds
. These bearings offer a low level of noise, vibration, and frictional torque performance. Miniature and extra-small ball bearings can be sealed by shields or rubber seals to prevent leakage of lubricating grease or entry of dust.
What are tiny ball bearings used for?
Bearing Basics applications, miniature precision bearings
help reduce friction between parts that need to move independently while effectively saving space in tight applications, such as medical, instrumentation and semiconductor equipment
.
The balls are available in a range of sizes to meet specific project needs.
Where is
miniature ball bearings be
used?
Ball bearings are the most common bearing type and can be found in many every day objects, such
skateboards, blenders, bicycles, DVD players and photocopiers
.
Small wheel bearings are also frequently be used for window and door rollers.
This type of bearing is typically used in applications which have a high speed and a low load.
About HXHV S
mall Ball Bearings
The
micro bearing
dimeension
are usually standard as the table below.
But sometimes buyer need the
non-standard bearings with custom small bearing size or
micro blue bearing
.
We supply
OEM SERVICE
and produce these non-standard bearings with
customized size, logo and packing
.
CE CERTIFICATE
is very important for european market. And we supply CE certification for our bearings.
As for the
mini ball bearing material
, the inner ring, outside ring, balls and retainer are usually be made of carbon steel, chrome steel or stainless steel. Sometimes the retainer can be made of nylon.
The bearings are also be made of special material such as black ceramic Si3N4, White Ceramic ZrO2, and PTFE, PEEK retainers.
Sometimes we make the mini bearing with plastic POM rings and glass balls.
The
micro ball bearings price
will be different because of the bearing's model number, order quantity, precision range, brand and packing, etc.
If you need any original brand bearings or bearing with other dimension and model number, please contact us directly.
Material
:
Standard bearing's material is
chrome steel (GCr15)
. It is also called bearing steel. The material can become oxidized and rust after prolonged exposure to humid air, so we filled them with oil or grease to prevend rusting.
Stainless steel bearing material
. We usually use 440 stainless steel to produce the bearing. It has stronger rust and corrosion resistance, so generally do not need to add lubricating oil or lubricant. Relative to bearing steel, stainless steel quality is better, the price is more expensive.
Full Ceramic or hybrid ceramic material
. The ceramics used in the production of bearings are generally
black silicon nitride
(Si3N4)
and
white zirconia (ZrO2)
.
Plastic bearing
are usually made of
POM
,
PA
inner and outside rings, glass balls and nylon retainer.
To reduce the cost and avoide rusting, buyers can also choose the cheap carbon steel material and zinc coated on bearing surface.
Retainer
:
Steel Bearing's retainer
are normally be made of stainless steel, chrome steel, carbon steel. And the retainer type is ribbon
steel retainer or crown steel retainer.
Full ceramic or hybrid ceramic bearings' retainer
are usually made of plastic POM, Nylon, or high polymer material PTFE, PEEK.
Type
:
ZZ type
---- Bearing is sealed by PTFE or PEEK retainer
Open type
---- Bearing comes without seal on any side.
Full Ceramic Type --- Bearings are made of Si3N4 or ZrO2 ceramic.
Hybrid Ceramic Type --- Bearings are made of steel rings and
Si3N4 or ZrO2 balls.
