5.5.4 Rolling Friction When a surface is rolled over another surface, the
resistance to motion is termed as rolling friction. With hard materials the
coefficient of rolling friction varies in the range of 5 x 10~3 to 10~5, while the
coefficient of sliding ...

Friction and Lubrication in Mechanical Design
7.1 ROLLING FRICTION The frictional resistance to rolling in dry conditions was
extensively investigated by Palmgren [1] and Tabor [2], who concluded that slip is
negligible and cannot be considered as the mechanism causing rolling friction.

2.5 ROLLING FRICTION Friction during rolling is important for applications such
as the performance of rolling element bearings and the rolling of sheet products.
The value of rolling resistance is a function of the coefficient of rolling friction
between metals, which increases as the load is increased. Rolling friction is
subject to too many variables for a direct mathematical determination. The types
of metals ...

Examinations of rolling friction have not played as a prominent role in history as
sliding friction, probably because rolling friction is much smaller in magnitude
than sliding friction and, therefore, less annoying. The first ideas of the nature of ...

Friction: Physical Principles and Applications
If F is the force necessary to keep an object rolling at some constant velocity v,
the rolling friction coefficient /ir is defined by fiR = F/L, where L is the load. We
note, however, that while the sliding friction coefficient fi is usually nearly
independent ...
Because of the complexity of the phenomena associated with rolling friction,
however, it is difficult to write quantitative laws pertaining to it (as has been done
in the case of sliding friction). Coefficients of rolling friction are generally in the
range ...

Bharat Bhushan. 6.2.7.2 Mechanisms of Rolling Friction In the case of rolling
contacts, rolling friction arises from the resistance to rolling and because of slip.
The magnitude of the resistance to rolling is usually much less than that during
slip.
