Axial load (or thrust load) is a force applied parallel to the longitudinal axis, whereas, a radial load is a force applied transverse to this longitudinal axis.

The “load” is the force applied to a bearing.

The “radial load” is the force applied perpendicular to the shaft.

The “axial load” is the force applied in the same direction as the shaft.

Deep groove ball bearings sustain both radial load and axial load coming from both directions at the same time.

Force that is applied perpendicular to the axis of a bearing's shaft. Radial loads are also called rotary loads.

PCR: Passenger Car Radial

TBR: Truck and Bus Radial

A TBR tire can handle a heavier load than a PCR tire, and it's usually bigger.

The pitch of the propeller causes this noise.
