Full ceramic bearing made with Si3N4 have some better performance than ZrO2, the rings and balls made by full ceramic material:Si3N4, as a standard constructure,the cage made by PTFE, generally we also could make the cage with GFRPA66-25,PEEK,PI, Phonemic Textiles Tube ,etc. Compares than the material of ZrO2 ,The SiN4 ceramics bearings could endure heavier load and could be used in higher temperature environment. Also we could offer precision ceramic bearing which generally used in high-speed and high-rigidity spindle.the manufactured clearance could be P4 TO UP grade.

Axial angular contact ball bearings, for screw mounting
The complete units are consisted of a single-piece outer ring, a two-piece inner ring, balls, cage assemblies and seals.
Bearings are double direction angular contact ball bearings with a 60° contact angle in an O arrangement.
can support axial loads from both directions as well as radial loads.
are preloaded after assembly by a precision locknut.
are protected from contamination by lip seals or gap seals.
are greased with a lithium complex soap base grease to SHELL Alvania RL3.
can be relubricated.
are suitable for operating temperatures from -30°C to +120°C (limited by the grease, sealing ring material and the plastic ball cages).

Ball Bearings
Ball bearings are machinery components, which comprise an outer ring, inner ring, balls, retainers, shields and snap rings. Miniature bearings and small-sized ball bearings have up to 30mm in external diameter. Essential to high-precision rotary components, ball bearings determine rotational accuracy.
Bearing types include Radial Ball Bearings (Deep Groove and Angular Contact) and Thrust Ball Bearings. Radial bearings are designed to carry both radial and axial (thrust) loads, while thrust bearings are designed for pure thrust loads only. Many different configurations are available for ball bearings.
Miniature Bearings
Our miniature bearings range in sizes from .1181 to 1.000 inch O.D. (3mm to 26mm), and are available in inch and metric sizes.
Miniature bearings and instrument bearings are single row bearings. The construction of these miniature bearings enables them to carry moderate radial and thrust loads at low operating torque while providing high performance within a small envelope design. Miniature bearings and instrument bearings are typically available in both stainless steel for those applications requiring corrosion resistance and chrome for maximum fatigue life.
Minebea manufactures more than 8,500 different types of miniature and small-sized bearings, most of which have external diameters of 22mm or less.

POM Polyoxymethylene can be used in tem-peratures ranging from -60°C to +100°C . The high surface strength is only surpassed by a few materials. POM shows good sliding roperties and high resistance to wear and tear because of the high strength and smooth surface. There is a very low risk of stress cracks. POM (Copolymere) exhibits a high thermal stability and a high resistance to chemicals (high resistance to hydrolysis).

The high performance stainless steel bearings can provides not only with the cleanliness and corrosion resistance characteristic also with the high accuracy and excellent wear resistance compare to the high carbon chrome steel bearings. The rings and balls are made of the material as a standard structure of stainless steel bearing, The rings and balls are made of the material of AISI440C (9Cr18Mo or 9Cr18), the cage and the framework of seal adoption the AI304 or AI316, production accuracy could reach ISO standard ABEC-1 and above, and the vibration level reach Z1 grade and above.

NSK manufactures a complete range of metric single row angular contact bearings from 10mm to 775mm bore diameter. The standard contact angles available are 15, 25, 30 or 40 degrees. A range of inch sizes is also available with a standard 20 degree contact angle.
These bearings are capable of supporting radial loads and axial load in one direction. The larger the contact angle, the higher the axial load carrying capacity. For high-speed operation, however, smaller contact angles are preferred.
Normally these bearings are used in duplex pairs in order to support axial loads in either direction. They can be supplied paired back-to-back or face-to-face with known preloads or clearances built-in. They can also be supplied paired in tandem to accept exceptionally heavy axial loads in one direction.
The most popular contact angle for industrial bearings is 40 degrees and these can be supplied with different cage materials including steel, brass or polyamide.

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.

Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. The raceways of the inner and outer rings are offset in relation to each other in the direction of the bearing axis. The bearings are available in open and sealed versions. Their self-alignment capacity is very small.
Many sizes of angular contact ball bearings are supplied in X-life design. These bearings are indicated in the dimension tables. Bearings of X-life quality have an improved raceway geometry as well as optimised surfaces. This gives a significant increase in the fatigue limit load of the bearings. In calculation of the expanded adjusted rating life, values up to 50% higher are achieved. In certain applications, a smaller design of bearing arrangement can therefore be used if necessary.
Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. They correspond in design to single row angular contact ball bearings in pairs in an O arrangement but give a narrower design than these. They differ in the size of their contact angle and the design of the bearing rings.
