Explore: Rolling Contact

Rolling Contact Fatigue (RCF) is a phenomenon that occurs in mechanical components relating to rolling/sliding contact, such as railways, gears, and bearings

exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as pure rolling. By definition, there

the rolling cylinders. If two equal cylinders are pressed together then the contact surface is flat. In the absence of surface friction, contact stresses

that it involves the rolling of one or more objects without releasing them into the air. Many of the techniques found in contact manipulation, such as

tractions in the contact patch. In 1967, Joost Jacques Kalker published his milestone PhD thesis on the linear theory for rolling contact. This theory is

motions at each ball/race contact. Overall, these cause bearing drag. Roller bearings are the earliest known type of rolling-element-bearing, dating back

vehicle and its contents above the ground are rolling contact; sliding contact; intermittent contact; no contact at all as with anything carried; or some combination

in pairs or small groups for insects and fruit, and making repeated rolling contact calls almost continuously. An alternative name is Pied Caterpillar-eater

(WEC), or white structure flaking or brittle flaking, is a type of rolling contact fatigue (RCF) damage that can occur in bearing steels under certain

sound of rapidly increasing frequency. As the disk rolls, the point of rolling contact describes a circle that oscillates with a constant angular velocity
