HM 261049/010- Tapered roller bearing-FGFA bearings

HM 261049/010 Single row tapered roller bearing

Tapered roller bearings are of the separable type, comprising an inner ring, outer ring, tapered rollers, and a cage. Through the matching of tapered raceways and rollers, they can simultaneously withstand substantial radial loads and unidirectional axial loads. Characterised by high load-carrying capacity and rigidity, they find extensive application in automotive hubs, machine tool spindles, construction machinery, mining equipment, and similar scenarios.
