  • Bearing friction, power loss and starting torque | SKF |

    The friction in a spherical plain bearing or rod end depends primarily on the sliding contact surface combination, the load and the sliding velocity. Because there are so many influencing factors that are not mutually independent, it is not possible to quote exact values for the coefficient of friction.

    Thrust bearings are rotary bearings that allow rotation between parts and support a high axial load at moderate speeds. Design varieties include ball thrust bearings, tapered roller bearings, fluid bearings and magnetic bearings. Due to their inability to support radial loads, thrust bearings must be paired with radial bearings for radial load support.
