Product description of FAG Bearing 32009-X-H

FAG Bearing 32009-X-H, it belongs to FAG Bearing > Rolling and Plain Bearings > Roller Bearings > Tapered Roller Bearings

With a wide range of designs to choose from, FAG tapered roller bearings are also customization to match your specific speed, load, contamination, temperature or vibration conditions. FAG Tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. This bearing construction accommodates combined loads and provides low friction during operation. By adjusting one single row tapered roller bearing against a second tapered roller bearing and applying a preload, a rigid bearing application can be achieved.

FAG tapered roller bearings are also made to Explorer class. FAG Explorer combines our expertise in bearing design, trichology, metallurgy, lubrication and manufacturing. FAG Explorer tapered roller bearings are typically used in bearing solutions where there is a need to increase performance, reduce friction or increase power density in applications.

FAG Bearing 32009-X-H, Tapered roller bearings comprise an outer and inner ring with tapered raceways as well as tapered rollers in a window cage. These are single row individual bearings, usually of open design, which for technical reasons are always adjusted against a second tapered roller bearing in a mirror image arrangement. Open bearings are not self-retaining. As a result, the inner ring with the rollers and the cage can be mounted separately from the outer ring.

Tapered roller bearings can support high radial and axial loads in equal measure. Depending on the arrangement, they are suitable when precise axial guidance of the shaft is required (locating bearing function), or when the bearing arrangement must have very high axial rigidity and be operated clearance-free or under preload.

FAG Bearing 32009-X-H, Tapered roller bearings are available as: single row tapered roller bearings of standard design matched tapered roller bearings (fitted in pairs in X, O or tandem arrangement, open design) integral tapered roller bearings (fitted in pairs, sealed on one side, not separable). Tapered roller bearings are particularly suitable where: • high radial loads occur • high axial loads act on one side • combined loads must be supported (radial and axial forces acting simultaneously) • precise axial guidance of the shaft is required (locating bearing function) • the bearing arrangement must have very high axial rigidity • the bearing position is operated clearance-free or under preload (single bearings are adjusted against each other) • high running accuracy is required • the load carrying capacity of angular contact ball bearings is no longer sufficient and the higher speed suitability of angular contact ball bearings is not required • the bearings are not required to compensate misalignment • the design objective comprises compact, rigid and economical bearing arrangements with a high load carrying capacity Load carrying capacity and speed comparison – single row tapered roller bearings/single row angular contact ball bearings Fr = radial load Cr = basic dynamic load rating nG = limiting speed

Tapered roller bearings of basic design

Fundamental design features

FAG Bearing 32009-X-H, Tapered roller bearings are part of the group of radial roller bearings. In contrast to the ball, the roller has a larger contact area perpendicular to the roller axis. As a result, it can transmit higher forces, has greater rigidity and allows smaller rolling elements under the same load. The single row and multi-row bearings comprise a rib-less outer ring, an inner ring with two ribs of different heights and a cage.The cage contains truncated conical rollers. The roller and cage assembly together with the inner ring forms a unit. The low rib retains, in conjunction with the cage, the rollers on the inner ring raceway; the high rib supports the axial force component arising from the tapered form of the rollers. While the tapered rollers roll on the raceways, they slide on the higher rib of the inner ring. The projected lines of contact of the tapered rollers intersect the projected raceways of the inner and outer ring at a point on the bearing axis. As a result of this geometrical characteristic, tapered roller bearings are highly suitable for supporting combined loads. This also prevents any kinematic forced slippage at the rolling contact.

FAG Bearing 32009-X-H,The high dimensional and geometrical accuracy of the rollers reduces running noise and vibrations

Due to the dimensional and geometrical accuracy of the tapered rollers, the rolling elements in a roller set are subjected to virtually the same proportion of load in the load range. In operation, this leads to low-noise and low-vibration running, as well as a high adjustment accuracy.
