Facing Groove Patterns



The groove pattern on a particular friction material is critical to its success. Many hours of testing and evaluation go into selecting the optimum pattern to be used on a material, which is specified on in a particular application. Grooves perform two major functions.

2 and 3 pass

Radial and Concentric

First they must remove the oil film between the plates and then keep the friction material surface supplied with oil to assist in dissipating energy during engagement. The rate at which this happens depend upon the grooving design and application parameters.
