Thrust spherical roller bearing is roughly the same as the spherical roller bearing. The raceway surface of the seat ring is a spherical surface centered on a point that is consistent with the central axis of the bearing. The rollers of this type of bearing are spherical, so they have self-aligning function, not very sensitive to coaxiality and deflection of the shaft.

The roller of the 29000 type spherical roller thrust bearing is an asymmetrical spherical roller, which can reduce the relative sliding of the roller and the raceway during operation, and the roller has a long length , a large diameter, a large number of rollers, a high load capacity , and is usually oil lubricated . Individual low speed conditions can be lubricated with grease. When designing and selecting, it should be preferred;

Different from other thrust bearings, this type of bearing has a very large axial load capacity, and can also bear several radial loads while bearing the axial load, but the radial load shall not exceed 55% of the axial load.

This type of bearing is mainly used in oil drilling rigs, iron and steel making machinery, hydraulic generators, vertical motors, propeller shafts for ships, tower cranes, extruders, etc.

• Minimal bearing arrangement deformation

under radial and axial loads

• Minimal bearing arrangement deflection

under moment loads

• Compact design

Why TKW Spherical roller thrust bearings 29492 EM?

• Steel

Improved, ultra-clean steel provides longer bearing service life, even under heavier loads.

• Heat treatment

A unique TKW heat treatment process significantly improves wear-resistance and fracture toughness.

• Manufacturing

Refined precision manufacturing processes allow the production of bearings that run smoother and maximize the effects of the lubricant between the contacting surfaces.

• Internal geometry

A fine-tuned micro-geometry of the rolling contacts provides better load distribution and reduced friction.The standard range of TKW spherical roller thrust bearings starts from a 60 mm bore diameter and goes up to a 1 600 mm bore. Larger sizes can be supplied on request.

Three bearing series for a wide range of applications

The standard bearings cover an extensive dimension range in the three ISO Dimension Series 292, 293 and 294. They satisfy the important selection criteria

• load carrying capacity

• rotational speed

• space in the application.

When very high load carrying capacity is required, bearings in the 293 and 294 series are suitable. The small cross section of the 292 series bearings have favourable speed, space and weight characteristics. Smaller and more cost-effective equipment can be designed for longer bearing service life or higher output as a result of the high combined load carrying capacity of TKW spherical roller thrust bearings. These bearings can operate at high speeds even under heavy load conditions.

Cages Bearings identified with the suffix E up to and  including size 68 have a stamped steel windowtype cage. All other bearings have a machined  brass or steel cage guided by a sleeve that is  fixed in the shaft washer bore. In all bearings,  the cage (and sleeve) forms a non-separable  assembly with the rollers and shaft washer.

Misalignment By virtue of their design, spherical roller  thrust bearings are self-aligning, i.e. they can  accommodate misalignment of the shaft relative to the housing and shaft deflections during  operation. The permissible misalignment is reduced  as the load increases. The values indicated can be applied provided there is constant misalignment relative to the housing  washer. In practice, this means no problem for the  vast majority of applications. Whether the permissible misalignment can  be fully exploited depends on the design of  the bearing arrangement, the type of seal etc. When designing bearing arrangements  where the housing washer is to rotate, or  where there is a risk that the shaft washer  will wobble.
