Slide bearing, hydrodynamic. Polymer slide bearing, polyamide, dry. Coefficient of friction for. The coefficient of friction in Table was computed by the formula given above.
Static Friction of Roller (Inches Diameter Between Plates).
The force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction. Rolling resistance friction. The rolling resistance can be expressed as.
Fr = rolling resistance or rolling friction (N, lbf). To illustrate this concept, two examples are included. Note that only the last of these effects involves friction , therefore the name rolling friction is to an extent a misnomer.
In analogy with sliding friction , rolling resistance is often expressed as a coefficient times the normal force.
This coefficient of rolling resistance is generally much smaller than the coefficient of sliding friction. Coefficient of Friction Level surface. The coefficient of friction for breakaway for moving a load on a smooth, har level surface should not exceed. On a hardened steel surface, this should be a little less.
