Manufactured in stainless steel, the new ultra [miniature 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 skf bearings with outer diameter of less than 22mm. To this distinction we now add: the largest manufacturer of the world's smallest ball bearing.


1. RF30Q deep grove ball bearing grinding line is ideally suited for producing miniature bearings rings (inner rings 10-30mm inner diameter, outer rings 26-62mm outer diameter).
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 nachi bearing rings (inner rings 80-160mm inner diameter, outer rings 120-250mm outer diameter).


miniature 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 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 timken bearings can be ideal.
