NSK manufactures a full range of metric and inch size miniature ball bearings with bore diameters of less than 10mm. These can be divided into two basic types, deep groove and angular contact ball bearings.
Deep groove ball bearings are the most common and NSK offer several variants for miniature sizes:
Standard type
Flanged outer ring type
Extended inner ring type
Synchro bearings with thick section outer rings
Extra-thin section type
In addition, NSK can also provide these bearings with shields or seals (contact or non-contact) on one or both sides of the bearing and pre-lubricated with grease.
For applications requiring higher speed, rigidity or axial load capacity, then miniature angular contact bearings are also available.

By virtue of its internal geometry, the self-aligning ball bearing is capable of accommodating small angular misalignments between the shaft and housing. This is achieved by using two rows of balls that run in parallel inner ring raceways and a full width, spherical outer ring raceway.
Caution must be exercised when thrust loads have to be accommodated as these bearings have very little axial load carrying capacity.
A tapered bore for mounting using an adapter sleeve is common and, as such, these bearings can be used in place of spherical roller bearings in plummer block applications.
NSK can supply a range of self-aligning ball bearings in metric and inch sizes from 5mm to 130mm bore.

RBC thin section ball bearings are engineered to solve a variety of
design problems that cannot be solved with conventional ball bearings.
A bearing is considered a thin section when the bore diameter is greater
than four times the radial cross section. Within any thin section bearing
series, the cross section remains constant as the bore diameter changes.
Typically the cross section is twice the ball diameter, and nominal
dimensions are given in inches.
RBC thin section ball bearings are most often found where space limitations,combined loading, and weight restrictions pose unique design
requirements.

Deep groove ball bearing, featured of simple structure and convenient using, is the kind of bearing that is used the most extensively in the world. With little friction coefficient and high limit speed, it can be used to bear axial load when the rotate speed is too high and thrust ball bearing is not suitable to be used.
ZQZ deep groove ball bearing (open) mainly incudes: 6000, 6200, 62200, 62300, 16000, 6300, 6400, etc.

In Aviation and Space applications rolling bearings are operating in extremely demanding environments. Although highest speeds, intense loads, extreme temperatures and compromised lubrication characterize the operating conditions, the bearings have to perform perfectly reliable. CEROBEAR has accepted the challenge to serve these demanding markets a decade ago and is since then strengthening its efforts to become and maintain a reliable partner to the industry.

SNR TOPLINE bearings benefit from SNR's state-of-the-art innovations, providing suitable solutions for the most extreme operating requirements.
This product range breaks down into 4 families, with bearings capable of sustaining temperatures from -60 °C (LT series) to +150 °C (FT series) and up to +200 °C (HT series), as well as high rotational speeds up to 700,000 N.Dm (HV series).
Fitted with steel cages, the Topline bearings are also proposed in sealed version (fluorinated elastomer or Viton seal, according to the series) or in protected version (deflector baffles, of lower cost, and suitable for higher rotational speeds).
The TOPLINE product range greases have been selected for their outstanding performance in application and submitted to thorough testing. 70 % of the bearing failures are attributable to lubrication: therefore, particular care has been paid to grease selection, now a major contributor to the quality of our bearings, guarantying their reliability and durability.

Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.
The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders).
Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation.
