29340 For Steel Machinery High Preformance Spherical Thrust Roller Bearing

Thrust Roller Bearings

Thrust Roller Bearings Features:

1): Able to accommodate misalignment
2): Suitable for high axial and some radial loads
3): Relatively high speed ratings

4): Heavy machine tools, high power Marine gearbox, oil rig, vertical motor machinery, Juki hooks,

vertical pumps, vertical centrifuge, jack, low speed reducer

Description of thrust spherical roller bearings:

1.single row, self-aligning roller bearings

2. They comprise solid shaft and housing washers and asymmetrical barrel rollers with cages.

3. The cage holds the roller and cage assembly together with the shaft locating washer.

4. The bearings can be dismantled. The parts of the bearings can be fitted separately.

5. Spherical roller thrust bearings can support very high axial loads and permit relatively high speeds. Since the raceways are at an angle to the bearing axis, the bearings can also support radial loads.

Thrust spherical roller bearings designs:

Bearings are produced in several designs which is mainly different in cage as following:

Bearings in "M" design have brass cages guided by a steel sleeve on the shaft washer.

Bearings in "J" design have pressed steel cages guided on the shaft washer.

Bearings in "J" design are interchangable with bearings with machined brass cage. If the bearings with machined brass cage is to be replaced in arrangement, where the shaft washer rests on the shaft on the face of steel sleeve which guides the cage by the bearings in "J" design, it is necessay to insert a spacer between the shaft washer and original shaft shoulder.

High Preformance Thrust Spherical Roller Bearing 29340 For Steel Machinery

Introduction:

1) Low friction
2) Minimum lubrication
3) Wear resistant
4) Running in not required
5) Requires little attention
6) Dimensions relatively small
7) No scraping required to fit shaft
8) Easy replacement

Thrust roller bearings consist of two precision chrome steel washers (ring) and a roller complement spaced by bronze retainer. They can be supplied with or without radius roller grooves in the rings. Thrust bearings

are used under purely axial loads.Bearing rings mounted on the shaft are called shaft washers, and those mounted in the housing are called housing washers. Both washers contain raceways for the rollers.
