Product Description

FPS ZERO-SHOCK Piston with Full Metal Rack

Product Description

FPS is proud to introduce the first ZERO-SHOCK Piston, featuring a proprietary technopolymer body and a full metal rack, 100% Made in Italy. This patented system significantly dampens the stress transmitted from the rack to the piston body, making the assembly markedly more reliable and durable than conventional pistons.

Key Innovations

  • Patented ZERO-SHOCK System: Attenuates stress between the metal rack and the polymer body, boosting overall reliability.
  • Body Material: Constructed from a reinforced Technopolymer with Elastomer added, providing high mechanical performance and a very low friction coefficient.
  • Rack Construction: The reinforced rack is made using MIM (Metal Injection Molding) technology (SAE 4650 + HRC 38−42 hardening treatment), ensuring dimensional precision and resistance equivalent to solid machining—currently considered the best material for this application.
  • Optimized AOE (Angle of Engagement): The rack features the second tooth missing and the third tooth pre-lowered by 0.3 mm, predisposing the piston for a correct AOE and making it suitable for high-speed setups.
  • Low-Friction Guides: Sliding guides are engineered to minimize friction and retain lubricant longer.
  • Centralized Loading: The rack housing is intentionally decentralized to promote optimal meshing between the piston rack and the sector gear teeth.
  • Reinforcement: Longitudinal reinforcements on the tooth sides enhance piston robustness and prevent the rack from contacting the inner cylinder wall.
  • Friction Reduction: Special internal ribs reduce the contact surface area between the spring and the piston body, minimizing friction during the spring's compression/expansion cycle.

Specifications

  • Denture: Full Metal Rack (MIM SAE 4650)
  • Body Material: Reinforced Technopolymer with Elastomer
  • Compatibility: 100% MARUI compatible
  • Origin: 100% MADE IN ITALY
