| Coefficient of Friction (Normal) | The coefficient of friction (μ) of a material under normal temperature conditions. The coefficient of friction (μ) of a material determines the retarding force (Ffriction) produced when two sliding surfaces are held against each other by an applied normal force (N). The equation concerning the process is Ffriction = μN. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Coefficient of Friction (Hot) | The coefficient of friction (μ) of a material under hot temperature conditions producing after the friction material have been used in a brake, clutch or power transmission system. The coefficient of friction (μ) of a material determines the retarding force (Ffriction) produced when two sliding surfaces are held against each other by an applied normal force (N). The equation concerning the process is Ffriction = μN. | ||
