29464 E-Thrust self-aligning roller bearing-FGFA bearings

29464 E Spherical roller thrust bearing with stamped steel cage

Thrust spherical roller bearings are precision transmission components specifically engineered for heavy axial loads. Their core comprises a housing ring, shaft ring, spherical rollers, and cage. Through the adaptation of spherical rollers to curved raceways, they deliver robust axial load capacity while automatically compensating for misalignment between the shaft and bearing housing (such as coaxiality errors), offering exceptional impact resistance.
