Duplication of a wear test bench


Time to Market reduction & Manufacturing cost reduction


Optimized test solutions

Customer needs

Renault designed a test bench specifically dedicated to the characterisation of friction and wear phenomena between the synchroniser and the pinion of gearboxes. Its goal was to make the duplicated bench available to the manufacturers of synchronisers and lubricant suppliers.

Customer benefits

The car manufacturer’s engineering departments, the manufacturers of synchronisers and the lubricant suppliers can now directly contact Cetim to carry out wear and friction tests approved by Renault

Cetim answer

Design of a duplicate test bench using the same measurement methodology and characteristics as those specifically developed by the tribology department of the Renault Technocentre materials laboratory.

Delivered results

Performance of cross-testing campaigns on reference lubricants and samples in order to adjust the influential parameters until the identical results were obtained.
