    • Cylindrical bearings, taper roller bearings & spherical bearings have high radial load carrying capacity. All three can be used as a roller element in roller bearings.

    • Cylindrical bearings have high load transmitting capacity than ball bearing.

    • Conical rollers running on conical races are used in tapered roller bearings.

    • Relative motion of races causes rolling of roller elements. Earlier sets of logs were laid on ground with a large stone block on top as rolling-element bearings. Logs roll along the ground with friction when stone was pulled.
