The customer's request

Substituion of the current pulley with an equal plastic component

Project goals:
> 40% reduction of the component cost
> 50% reduction of the lead time production
Ensure less wear of the drive belt

The challenge

Redesigning a component subjected to strong mechanical stress;
Guarantee of concentricity between the bearing and the gearing;
Extreme precision and high finishing of the gearing;
Realization of the component in a single production phase.

The solution

Integration of the bearing and threaded inserts by overmoulding process;
Use of a self-lubricating technopolymer reinforced with glass fibers.
