Manufactured in stainless steel, the new ultra small 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 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 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 bearing.

1. RF30Q deep grove ball timken bearing grinding line is ideally suited for producing small bearings rings (inner rings 10-30mm inner diameter, outer rings 26-62mm outer diameter).

2. RF50Q automatic production line is ideally suited for producing small 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 small bearing rings (inner rings 40-100mm inner diameter, outer rings 100-200mm outer diameter).

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

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.

 

These fag 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 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.

small 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 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 nachi bearing into the application.
