Shear Stength Test (SST)
Machine used to determine the adhesion strength between the friction material and the metallic pad to which it is bonded.
The disk brake pad under test is mounted in a specially designed fixture to allow the application of a load to compress a face of the friction material by a vertical pressing cylinder;
A cylinder applies an incremental force of cross-sectional cut by means of a cutter blade;
The control system records the force applied at the moment of the separation of the friction material from its support.
Fixtures of easy construction;
Cutter blade with an insertion device for simple and quick type change;
Automatic computing of the cut effort: relationship between the cutting force and the surface of the brake disc pad under test;
Possibility to execute tests constituted of some measures, with automatic calculation of the minimum, maximum and mean values of the compression load and the cutting effort;
Automatic generation of graphic reports;
Management of archives of test descriptions;
Automatic management of the archives of the results of the executed tests.

with maximum width 200 millimeter;
Maximum cutting blade approach stoke: 50 millimeter;
Maximum cutting force : 100 kN;
Force of vertical compression cylinder : 50 N/cm
