The ballscrew undergoes a silver coating a primary gold deposit which ensures a high mechanical and perfectly constant efficiency wichever is the position of the snubber. This coating also gives perfect corrosion protection.

The breaking system consists of fixed and mobile disks immerged in a high viscosity fluid. The fluid is always at atmospheric pressure thus leakage is excluded.

The exterior protection is a chemical nickel plating and an outside stailess steel cover.
