Manufactured in stainless steel, the new ultra small ball bearings have the same high precision, durability and rigidity structure as all the other miniature ball bearings that Minebea manufactures. The width of 0.65mm can be slimmed down to 0.4mm for low speed. This ultra small ball bearing contains 6 balls with a diameter of 0.25mm.

How small is small? With an outside diameter of 1.50mm, inside diameter of 0.50mm, width of 0.65mm, and capable of high speed rotation of more than 5,000 rpm, this new ultra small ball bearing is definitely tiny.

Applications for this new product will be in ultra small devices that require extreme precision on a nano scale, such as miniaturized medical devices, micro-motors, micro machines and others.

Deep groove ball bearings are available in a variety of sizes, and are the most popular of all rolling bearings. This type of bearing supports radial load and a certain degree of axial load in both directions simultaneously.

Shielded/sealed type

Simplifies sealing structure of applications.

Greasing is not necessary because bearings are pre-lubricated.

 With locating snap ring

Bearings with a locating snap ring can be fit to the housing easily, as the locating snap ring facilitates axial positioning.

 Extra-small ball bearings and miniature ball bearings

The open type is widely used. Also available are the shielded/sealed type and the flanged type; the latter is easily positioned in the axial direction.

 Maximum type ball bearings

These bearings are single-row deep groove ball bearings with a filling slot on both the inner and outer rings. They feature an enhanced radial load rating as they can contain more balls of larger diameter.Not suitable for applications that involve axial loading or high-speed rotation.

When the bearing is installed, the filling slot on the fixed bearing ring should be in a no-load area.

small ball bearings, or small TIMKEN 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.
