PISTON MODEL ZERO SHOCK CU DINTI METALICI
The type of metal injected is SAE 4650 + HRC38-42 hardening treatment which is currently considered the best material on the market for this type of use.
The sliding guides are designed to minimize friction and retain the lubricant for a long period of time.
The rack seat is decentralized to favor the coupling between the piston teeth and those of the sector gear.
The longitudinal reinforcements at the sides of the teeth increase the robustness of the piston and avoid contact of the rack with the inner wall of the cylinder.
Special ribs decrease the contact surface between the spring and the internal part of the piston body and consequently also the friction between metal and technopolymer is decreased during contraction and elongation due to the firing cycle.
