29424EX Nachi

The 29424EX Nachi is a spherical roller thrust bearing. This type of bearing can handle high radial loads and extremely high axial loads in one direction simultaneously. The specially designed raceways of this bearing accommodate a large number of asymmetrical rolling elements. These rollers transfer the load from one raceway to another. This occurs at an angle relative to the bearing axis, while a flange on the shaft ring guides the rollers. Spherical roller thrust bearings, also known as axial spherical roller bearings, have the highest load-carrying capacity of all thrust bearings. Additionally, they can achieve relatively high rotational speeds.

The 29424EX Nachi allows for a compact bearing arrangement. Additionally, this bearing can accommodate misalignments. Spherical roller thrust bearings are self-aligning, allowing them to handle slight misalignments between the shaft ring and the housing ring. Shaft deflections, alignment errors, and housing deformations can be compensated to some extent by the bearing. Spherical roller thrust bearings are often mounted in conjunction with spherical roller bearings to increase the axial load capacity of the bearing arrangement. Common applications include turbines, generators, and hydraulic presses.
