[Solved] Tapered roller bearings can take

Tapered roller bearings are capable of carrying both radial and axial loads but largely used for appliions where radial load component predominates.They are often used in pairs to take the thrust load in both directions. The taper roller bearing consists of rolling elements in the form of a frustum of cone.
