Transmission bearings in race cars normally only attract attention when they fail. So apart from absolute reliability, they also have to provide minimum friction, low weight and, in some applications, as many integrated functions as possible. Custom-made designs to meet specific requirements offer an ideal combination of these properties.
CEROBEAR hybrid transmission bearings are available as several rolling bearing types with balls, rollers, needles or tapered rollers, made of silicon nitride. A design that is matched to the stress and the choice of suitable materials helps save weight compared to standard bearings. Customized flanges, anti-rotation devices, threads, splines or oil feeds allow an optimum connection to the surrounding structure.

The wheel bearings of modern, high-performance race cars are normally paired, axially-preloaded hybrid angular contact ball bearings with integrated seals. The main requirements are maximum stiffness for a reduced and uniform brake and tyre wear, low weight to reduce the unsprung masses, minimum friction and maximum reliability.
CEROBEAR hybrid wheel bearings offer optimum performance through an individual bearing design and ideal combination of materials. The best results are achieved by using silicon nitride and high-nitrogen steels as rolling contact partners, whereas modern, high-performance plastics are ideal materials for the cages and seals.
Designs with a high contact angle and tight raceway curvatures are nowadays dominating, since they achieve a very precise and extremely stiff brake disc and tyre guidance for the most demanding load case, which is fast cornering. At the same time, an increase in the axial bearing load capacity and widening of the virtual bearing distance allows a smaller bearing size to be used for maximum weight saving.
Many teams from the Formula 1, World Rally Car, Formula 3, LeMans 24h, ALMS, DTM and NASCAR have recognised these advantages and thus use CEROBEAR hybrid wheel bearings with great success.

Axial needle roller bearings
Axial needle roller bearings are units comprising axial needle roller and cage assemblies and axial bearing washers with a centring spigot. They can be combined with drawn cup needle roller bearings and needle roller bearings. The axial running surface for the needle roller and cage assembly must be hardened and ground.
Axial needle roller and cage assemblies
Axial needle roller and cage assemblies comprise plastic or metal axial cages with integrated needle rollers and have a very small axial section height. They can support high axial forces in one direction. Radial loads must be supported by separate means. Axial needle roller and cage assemblies require hardened and ground axial running surfaces for use as raceways.

IKO Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings. They can take loads from any directions at the same time such as radial, thrust and moment loads. The rollers make line-contact with raceway surfaces, and , therefore, elastic deformation due to bearing loads is very small. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel or those with inner and outer rings provided with mounting holes are also available on request.
|
|
high rigidity
Both inner and outer rings have a solid one-piece construction. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the rollers for smooth rotation, these bearings are suitable for applications where rotational speed is comparatively high.

Four-row cylindrical roller bearings are used almost exclusively in the metal industry(Rolling mills). Their friction is relatively low when compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.
Since very many rollers can be incorporated, the radial load carrying capacity is exceptionally high. Multi-row cylindrical roller bearings are unable to accommodate axial loads but they can be mounted together with deep groove or angular contact ball bearings or with tapered roller bearings to help accommodate any axial loads.
HOYI is very accomplished in making Four row cylindrical roller bearings. The dimensional accuracy is P6 and running accuracy is P5 (same with SKF accuracy) We have seen the over inflated prices and the impossibly long lead times being offered. We are offering a quality alternative, with very reasonable lead times and at a competitive price.

NSK manufactures a complete range of cylindrical roller bearings. Both metric and inch sizes are available in bore sizes ranging from 1/2" to 1320 mm.
By virtue of the line contact between rolling elements and raceways, cylindrical roller bearings have high radial load capacity and are suited to high speed applications.
There are several designs, designated NU, NJ, NUP, N or NF for single row bearings and NNU or NN for double row types. In each case, the designation defines the bearing ring rib configuration.
For single row bearings NU and N types the inner and outer rings can move axially, in both directions, relative to one another. These are suited to use as ‘free-end’ bearings.
The other configurations are capable of sustaining axial loads. Double row bearings are used primarily in machine tool applications having high radial rigidity. Both NNU and NN configurations are ‘free-end’ types.
Pressed steel, machined brass and polyamide cages are available. Single row extra capacity designs can also be supplied.
For the steel industry NSK manufactures a range of four-row cylindrical roller bearings. These are primarily designed for use as steel mill roll-neck bearings.

Axial cylindrical roller bearings comprise axial cylindrical roller and cage assemblies and shaft and housing locating washers.
The bearings have particularly small axial section height, have high load carrying capacity and high rigidity and can support axial forces in one direction.

Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers coming into contact with each other during rolling.
The cylindrical roller bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with suffix E have a larger roller set and are thus designed for extremely high load carrying capacity.
The bearings can be taken apart and can therefore be fitted and dismantled more easily. Both bearing rings can therefore have an interference fit.
Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.

Full Complement Cylindrical Roller Bearings are designed to carry heavy load. Comparing with traditional bearings with cage, full complement cylindrical bearings have much higher loading capacity. The radial cross section of the type of bearings is very small. So it can be very sp0ace-saving. However the limiting speed of the bearings is relatively lower. All the multi-row cylindrical roller bearings are with a lubrication groove and one nipple on the outer ring.
