Floating Groove & External Guide

Traditional rigid pistons cause abnormal friction against cylinder walls, generating metallic micro-particles that contaminate the hydraulic circuit. Injoy's floating groove ensures the O-ring seals within the groove while the groove top remains decoupled from the cylinder bore. This eliminates metal-to-metal friction at the source, preventing iron scrap generation and preserving hydraulic oil purity.

2.Compact External Guide: Shorter & Stronger

Designed for space-constrained marine environments, our structure achieves a shorter axial dimension than conventional designs without sacrificing support strength. This compact refinement increases spatial efficiency while facilitating superior accessibility for protective coating applications.

3.Coating Reliability: Away from the "Impact Zone"

• Conventional designs often place coating joints in high-impact zones, making the coating vulnerable to cracking and delamination upon external impact.

• We strategically position coating joints away from impact-prone end faces. Even during harsh on-site installation or accidental collisions, the vulnerable coating interfaces remain protected, significantly enhancing the long-term integrity of the corrosion barrier.
