This study presents the design, manufacture and validation of pin-on-disc bench for wear. For studies of sliding friction and wear of ceramics is generally applied pin-on-disc apparatus. This type of equipment has been referred the best one is the study of wear and shows better reproducibility of results in different laboratories. This work, in compliance with current standards and care of interests of different users, researchers and technicians, objective the design and manufacturing of a pin-on-disc bench for testing of samples with varied dimensions and obtained by different manufacturing techniques. The entrances of project providing for the maintenance of the sliding velocity and torque during the experiment, calibration of load on the equipment, measuring coefficient of friction during running, possibility of wet or dry test and damping vibrations. A compact prototype was built and validated with wear of tribologic alumina samples pair. Affordable and reproducible equipment was obtained based on: driven by servo motor, synthetic granite table and suspension pads for vibration dampening and continuous measurement of frictional force during the experiment. For the validation was applied alumina tribologic pair, load at 30 N, and sliding velocity at 0.5 m/s. The maim results was wear rate as 15x10-6mm3/N.m and wear volume as 1.2 mm3after 4000m of sliding, the friction force was an average 23 N, these results are consistent with similar studies.
