China Factory Nu238em, Em E, High Quality

Inpro supply a range of miniature ball bearings and small bearings from stock. These chrome steel miniature bearings are available open, shielded or sealed with bore sizes as small as 3.00mm.

Miniature bearings are sometimes referred to as instrument bearings or micro bearings. We provide metric sizes for applications as varied as gyros, anemometers, miniature gearboxes, small motors and radio controlled models.

Our metric miniature ball bearings are supplied in GCR15 chrome steel and can withstand heavy radial loads and moderate thrust loads in both directions. Certain sizes can be supplied with the TW high-speed synthetic cage.

A rolling-element bearing, also known as a rolling bearing,[1] is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.

One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See "bearings" for more on the historical development of bearings.

A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between the shaft and hole. As the shaft turns, each roller acts as the logs in the above example. However, since the bearing is round, the rollers never fall out from under the load.

Rolling-element bearings have the advantage of a good tradeoff between cost, size, weight, carrying capacity, durability, accuracy, friction, and so on. Other bearing designs are often better on one specific attribute, but worse in most other attributes, although fluid bearings can sometimes simultaneously outperform on carrying capacity, durability, accuracy, friction, rotation rate and sometimes cost. Only plain bearings are used as widely as rolling-element bearings.
