Example 1:

Conveyor belt system in a manufacturing plant: The rollers which support the belt are bearing the radial loads due to the weight of the material transported. Bearings help ensure that these rollers rotate smoothly, while maintaining the efficiency of the conveyor system.

Example 2:

Heavy machinery gearbox: Cylindrical roller bearings in a gearbox manage radial loads. These help maintain a smooth rotation of gears when the force is acting perpendicular to the shaft.


  • Roller Bearings: Cylindrical or tapered roller bearings are common components designed to handle radial loads efficiently.
  • Bushings: In mechanical systems, these are used to support radial loads and keep friction to minimum.

Applications: Here are some of the scenarios where you will find radial load being applied:

  • Wheel Bearings in Vehicles: In wheel bearings, the force is exerted perpendicular to the axle, supporting the weight of the vehicle. Therefore this manages radial load. Electric Motors: Bearings in electric motors that require smooth rotations endure radial loads under the influence of gravitational forces.
