Product Detail
<p>
<strong>Miniature Ball Bearings 6300 Series</strong> are useful in a wide variety of applications. Bearings in general are devices that allow parts to move relative to one another in a constrained fashion. This motion may be linear or in rotation.
</p>
<p>
The two most common types of bearings are plain bearings and rolling bearings. The most well-known of the rolling variety of bearings is the ball. <strong>M</strong><strong>iniature & Instrument Ball Bearings 6300 Series</strong> can be highly effective at reducing friction between two parts that need to move freely.
</p>
<p>
There is some elasticity to the ball allowing it to support and move a range of bearing loads. Naturally, the balls in such bearings come in a variety of different sizes, from fairly large to miniature. Small Bearings can be extremely useful in applications where space is limited, such as automotive, electrical and medical devices.
