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.

We offer a full line of full ceramic & ceramic hybrid bearings specifically suited to bicycles. Various ABEC tolerances, radial plays, retainer styles and seal/shield configurations are available.
To make things easier for you we have compiled bearing kits and listed them according to the manufacturer and model of the bike component that the bearings will fit.
Our Ultra Seal line of ceramic hybrid bicycle bearings are specially designed for On Road and relatively clean riding environments.
Our Yellow Seal line of ceramic hybrid bicycle bearings are specially designed for Off Road and excessively dirty riding environments.
All sealed bearings are packed in grease and will require a short break in period to loosen up.
Dry Lube Any Bearing!
If you are on a quest for reducing the rolling resistance of any steel or ceramic hybrid bearing without the heavy investment that Full Ceramic bearings require, then our Ultra Dry Lube (UDL) coating process is for you. UDL can be applied to any metal substrate and it greatly reduces friction to about half that of graphite. This allows bearings to be run completely dry without any need for grease or oil. The result is a super free spinning bearing that does not have the typical drag associated with a bearing packed in grease or oil.

Conventional all steel bearings limit design potential as technology requirements roll forward at a fantastic rate. Ceramic Hybrid bearings offer a long list of characteristics far superior to that of conventional all-steel bearings.
Ceramic hybrids are a mixture of steel races and ceramics balls. The most common ceramic ball used, because of its hardness, is the Silicon Nitride (Si3N4) ball, although in certain environments either Zirconia (ZrO2) or Alumina Oxide (Al2O3) can be used. Ceramic hybrids offer higher RPMs due to the non-porous ball surface, longer life due to having a greater Rockwell hardness than steel and decreased weight as a result of being 2/3 the weight of steel. Ceramic hybrids are ideally suited to any application looking to achieve increased speed, durability and heat dissipation.
Stainless Steel Series: Stainless Steel resists corrosion in atmospheric, pure water environments as well as most acids, alkaline solutions, and chlorine environments. The easy cleaning ability of stainless makes it the first choice for strict hygiene conditions, such as dental tools, hospitals, kitchens and other food processing envoronments.
Ultra Seals Series: The Ultra Seal is a non-contact, frictionless seal that is placed beneath the metal shields. Say goodbye to dirt, dust and other contaminants without any increased drag. These bearings are maintainence free and lubed for life.
Ceramic Hybrid Series: Ceramic is the new Holy Grail! Its lighter, smoother, stiffer, harder, corrosion resistant, and electrically resistant. These fundamental characteristics allow for a wide range of performance enhancements in bearings.

The xiros polymer ball bearings are single-row grooved ball bearings based on DIN 625. The lubricant-free and maintenance-free ball bearing consists of four components.
- The outer ring
- The inner ring
- The cage
- And the balls
The inner and outer rings are made of igus tribopolymers to maximize service life and minimize coefficients of friction. In contrast to metallic ball bearings, xiros polymer ball bearings manage absolutely without lubrication. For this reason they are suited for a multitude of applications that depend not on extreme rotary speeds or loads, but just on lubricant-free application in contrast to permanently lubricated metallic ball bearings. These areas are for example food and medical industries, packaging and textile industries, or the chemical industry and cleanroom applications as well as electronics and office technology.

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.
|
|
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.

Angular contact ball bearings can stand a combined radial and axial load simultaneously. Its axial load carrying capacity increases with respect to the bearing's contact angle. The contact angle () is defined as the angle between the line contacting the raceway and ball. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle.
|
|
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.
