29464EJ Thrust Spherical Roller Bearing, Window-type Steel Cage
The 29464EJ Spherical Roller Thrust Bearings are suitable for heavy-duty applications involving alignment errors and impacts. Classic applications include large gate hoists in hydraulic engineering, ship stern tubes, mining crushers, continuous casting machine slewing tables, large crane slewing supports, and oil drilling rig rotary tables.
The 29464EJ bearing is a Thrust spherical roller bearing with an inner diameter of 320 mm , an outer diameter of 580 mm, a width of 155 mm. It typically uses PN (ABEC-1) grade precision tolerances and bearing steel rings, bearing steel rolling mlement. Its dynamic axial rated load is approximately 5636829 N, its static axial rated load is approximately 17096612 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
29464EJ bearings ( 320 mm x 580 mm x 155 mm) have the advantages of withstand extremely high axial loads and has a self-aligning function to compensate for installation errors or shaft deformation, and are therefore widely used in the Ship propulsion systems, oil drilling rigs, large cranes, hydroelectric generators, and heavy-duty gearboxes.

The 29464EJ Spherical Roller Thrust Bearings primarily consist of a shaft ring, a housing ring, asymmetrical drum-shaped rollers, and a cage assembly. The housing ring features a spherical raceway design, allowing the rollers to automatically adjust for alignment errors between the shaft and the housing ring.
The advantages of Spherical Roller Thrust Bearings lie in their superior self-aligning capability, effectively compensating for misalignment caused by installation skew or shaft deformation. They also possess extremely high axial load capacity, can withstand certain radial loads, and exhibit excellent impact resistance.
