If you drop a bearing, discard it. In addition to the fact that it may immediately accumulate damaging particles, there may be damage to the bearing which is not apparent to the naked eye. This damage may interfere with your application's efficiency or, at the very least, cause the application to generate a great deal more noise than desired. Also, when applying lubricant to your "small bearings", make sure that the lubricant is free from contaminants and refrain from using applicators like cotton swabs that could themselves contaminate the bearings.

Ball bearings are machinery components, which comprise an outer ring, inner ring, balls, retainers, shields and snap rings. Miniature and small-sized ball bearing mean ball bearing, up to 30mm in external diameter. Essential to high-precision rotary components, ball bearings determine rotational accuracy

Manufactured in stainless steel, the new ultra miniature 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 miniature 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 miniature 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.

With a 60% share of the global market, Minebea is the leading manufacturer of miniature ball bearings with outer diameter of less than 22mm. To this distinction we now add: the largest manufacturer of the world's smallest ball nsk bearing.

2. RF50Q automatic production line is ideally suited for producing miniature bearing rings (inner rings 17-50mm inner diameter, outer rings 40-100mm outer diameter).

3. RF100Q deep grove ball bearing grinding line is ideally suited for producing miniature bearing rings (inner rings 40-100mm inner diameter, outer rings 100-200mm outer diameter).

4 .RF160Q automatic production line is ideally suited for producing miniature bearing rings (inner rings 80-160mm inner diameter, outer rings 120-250mm outer diameter).

miniature ball bearings are simply another name for miniature ball bearings. Miniature ball bearings are typically very small, smaller than an inch or two, or smaller than 20 millimeters under metric measurement standards.

miniature ball bearings are composed in a variety of parts, including an outer and inner ring, balls, retainers and snap rings. They may also have shields or seals, flanges and steel ball cages. Miniature ball bearings come in a number of different types. They can be radial ball bearings, designed for radial loads, which will be either deep groove or angular contact bearings, or they can be axial ntn bearings, designed for thrust loads. They can have flanges for stability or no flanges. They can be shielded or open. Shielded small bearings offer additional protection in both directions, as they help prevent contamination into the bearing and also help prevent lubrication leakage from the bearing into the application.
