miniature ball bearings, or small bearings,
are specially designed to reduce friction between moving parts in various
industrial applications. Since many applications require large parts and may be
subject to a limited amount of space, the reduced size of small bearings can be
ideal.
There is a wide variety of applications for miniature ball bearings. Small
bearings can be used for medical applications, in anything from dialysis
machines to medical robotic devices. They may be used in office products such as
check and money sorting machines, or in computer peripherals like hard
drives.
Smaller balls or rollers deform more sharply, and so tend to fatigue
faster. Pressure-induced welding can occur when two metal pieces are pressed
together at very high pressure and they become one. Although balls, rollers and
races may look smooth, they are microscopically rough. Thus, there are
high-pressure spots which push away the ina
bearing lubricant. Sometimes, the resulting metal-to-metal contact welds a
microscopic part of the ball or roller to the race. As the bearing continues to
rotate, the weld is then torn apart, but it may leave race welded to bearing or
bearing welded to race.
It's not enough to know that you need miniature ball bearings for your
applications. Ball bearings come in a wide variety of combinations, types and
styles, and you will want the bearings that will provide the greatest efficiency
for your applications. There are different materials, such as chrome and
stainless steel, available. SRG small nsk bearings
are generally manufactured with DD400 stainless steel material. This reduces
noise for applications that are noise sensitive and provides superior corrosion
resistance and hardness. However, chrome material ball bearings are also
available. There are the different types discussed above, open vs. shielded,
flanged vs. not flanged, radial vs. axial load ball bearings. There are also
different types of shields and seals to consider. Finally, there is the actual
size of the bearing.
Bearings can be measured in inches or metrically in millimeters. There are
three main dimensions along which bearings are measured. These are the bore, or
inner diameter, the outer diameter, and the width. There are standard
designations given to miniature ball bearings to indicate their bore size. For
the standard series bearing, a 00 designation indicates a 10mm bore, 01
indicates a 12 mm bore, 02 indicates a 15 mm bore, 03 indicates a 17 mm bore,
and 04 indicates a 20 mm bore. For larger ball bearings, the measure of a
standard series bore in millimeters is five times the numeric designation.
miniature ball bearings are of the highest quality and are designed to last
and keep your applications running for a long time. However, as with any machine
parts, proper care and handling is a critical factor in making your bearings
last. The best way to protect your small bearings is probably the use of seals
and shields for your ball bearings. These features are specifically designed to
prevent contamination. That being said, some dirt or other particles may still
find their way into the bearing, which is why it is important to take other
steps to protect your bearings. This means that when you are putting your "miniature
ball bearings" into your application, you should take extra effort to avoid
any kind of contamination. Keep the room where you will be handling the bearings
dry and clean, and do not take the bearings out of their packaging until you are
ready to use them.
