This can be achieved by selecting the dimensions and materials so that their possible degradation does not affect the performance of the system.
To lower the warranty and repair costs for example, better materials and manufacturing processes which result in tighter tolerances, are usually needed increasing the production cost.
The design must provide sufficient torque without exceeding material compressive strengths.
