Axial loads or thrust loads occur along the horizontal axis or parallel to the rotating shaft or assembly.

Radial loads are applied on a vertical axis along the external surface of the outer ring, which also means that it is perpendicular to the axis of rotation.

Bearings and Loads
When used for lighter loads, ball bearings can easily handle both axial and radial loads. However, the smaller contact points of the spherical balls don’t provide much support against heavier radial loads, which can deform the shape of the different bearing components.

Roller bearings are more suitable for heavy radial loads, but do not spin as freely along its rotating axis – reducing its capacity for axial loads.

Tapered roller bearings are typically used for applications where bearings are subjected to heavy axial and radial loads at the same time.

These share the same basic components as straight roller bearings, but have a conical or tapered shape that allow it to support both heavy radial loads and moderately high RPMs. Due to its design, tapered roller bearings are designed to be very durable and long lasting.
