Roller bearing 7804 6-7804Y single row tapered roller bearing oe number 2101-3103025 for vaz 2101-2107 vaz car wheel

Single row tapered roller bearing structure:

Single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e (from the data table): the larger the value of e, the larger the contact angle.

Tapered roller bearing advantages:

have a design and internal geometry that provide long service life

have crowned raceway profiles and an optimized surface finish of the inner ring guide flange that enables them to run cooler and consume less lubricant than conventional design bearings

have load rating values that are in accordance with ISO and even above (data table)

offer a cost-effective solution for standard industrial applications

Low friction
The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.

Long service life
The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of  Explorer bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles).

Enhanced operational reliability
Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

Consistency of roller profiles and sizes

Bearing dirscription:

The inner ring with roller and cage assembly can be mounted separately from the outer ring (cup). Furthermore, the separable components are interchangeable. This facilitates mounting, dismounting and also maintenance inspection routines.

The bearing is roller, angular contact, tapered (or this type is also called "with tapered rollers"), single-row, basic design, wide series. This design allows it to be used as hub bearings ( front  VAZ bearings ). Manufactured according to the sixth degree of accuracy. Contact angle? in this type it is from 10 to 18 °. With an increase in the taper of the outer ring, the axial load capacity increases and the radial load decreases. During operation, avoid very small and vice versa, excessively large clearances, which can lead to an unacceptable increase in operating temperature and even destruction of bearing parts.

Bearing 7804 is the front bearing of the VAZ hub of models from 2101 to 2107 (outer support, bearing 7805 is placed on the inner support ), as well as the rear bearing of the Oka hub, can also be installed in the hubs of other cars. It has practically no other areas of application, however, due to the fact that the above-mentioned models are still quite widespread, the need for it is very high.
