LIGHTWEIGHT PISTON FULL META RACK FPS 14 TEETH (PM01)

TECHNICAL FEATURES:

-POM C was chosen for the piston material, a technopolymer with high mechanical performance and a very low friction coefficient as it is self-lubricating.
-The rack was manufactured using MIM (Metal Injection Molding) technology, as this production process guarantees dimensional precision and robustness equal to those of solid machining.
-The rack is presented with the second tooth missing and the third already lowered by 3 tenths of a millimetre, as this configuration predisposes the piston itself for a correct angle of engagement (AOE) and makes it suitable for high speed.
-The type of metal injected is SAE 4650 which is currently considered the best material on the market for this type of use.
-The slide guides are designed to minimize friction and retain lubricant for a long period of time.
-The rack seat is off-center to facilitate coupling between the piston teeth and those of the sector gear.
-The longitudinal reinforcements on the sides of the teeth increase the strength of the piston and prevent contact between the rack and the internal wall of the cylinder.
-Special ribs reduce the contact surface between the spring and the internal part of the piston body and consequently the friction between metal and technopolymer is also reduced during the contraction and elongation due to the firing cycle.
