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.

Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain; they are available in single and double row designs and and in open and sealed variants. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields.
|
|
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.

Radial insert ball bearings are single row, rady-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides, cages made from plastic or sheet steel and P, R, L or T seals. Bearings with an inner ring extended on both sides undergo less tilting of the inner ring and therefore run more smoothly.
The outer ring has a crowned or cylindrical outside surface. In conjunction with an INA housing matched to the bearing type, bearings with a crowned outside surface compensate for shaft misalignments; see Compensation of misalignments.
They are located on the shaft by means of an eccentric locking collar, grub screws in the inner ring, an adapter sleeve, drive slot or fit. Radial insert ball bearings are particularly easy to fit, suitable for drawn shafts of grade h6 to h9 and, with a few exceptions, can be relubricated.

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.

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.

Satellites and Space Rockets require various bearings created under special specifications of structure, design, material and manufacturing process, and NTN is one of the top manufacturers in this field.

Double direction axial angular contact ball bearings are non self-retaining precision bearings with restricted tolerances to class SP. They comprise solid shaft locating washers, spacer rings, housing locating washers and ball and cage assemblies with solid brass cages. The parts of the bearings are matched to each other and can be fitted independently of each other; they must not be interchanged with those of bearings of the same size.
|
|
|
Angular contact ball bearing run in higher limited rotation speed, can take radial load and axial load at the same time, and also can only take the pure axial load. The axial load carrying capacity of angular contact ball bearings increase with the increase of contact angle.

GWG produce large diameter angular contact ball bearing. In addition to standard items,GWG can make non-standard and custom beairngs with shorter lead time than expected.For more information,please view our homepage www.gwgbearings.com

SNFA's prime objective has always been to reach the highest levels of specialisation in the design, development and manufacture of precision bearings. The various series illustrated in this catalogue differ by configuration and size. They consist of bearings ranging in size from a minimum of 6 mm diameter bore to a maximum of 380 mm outer diameter.
Development has always been in line with international standards, as there is a need to safeguard interchangeability. Bearing specifications are therefore classed in accordance with such standards.
