The coefficient of friction of the glass filled slide plates is 0.06 forloads greater than 500 psi static.

The coefficient of friction of the glass filled slide plates is 0.06 forloads greater than 500 psi static.
The coefficient of friction of polish stainless steel slideplate is 0.1.
The reason for the use of slide plates is to reduce thecoefficient of friction between two surfaces. So to use an unpolished steelsurface, defeats the purpose of reducing the coefficient of friction.
