Solenoid Valve Retaining Ring

Manufactured from high‑strength alloy steel with a wear‑resistant coating and precision‑machined buffer ramp, the retaining ring maintains dimensional stability and consistent cushioning performance under repeated impacts. Key performance attributes include: ultimate impact load capacity ≥50 kN, dynamic compression‑rebound fatigue life exceeding 2 million cycles, and resistance to oil, salt spray, and a wide temperature range from -40℃ to 150℃. The inner diameter and fit tolerances are strictly matched to define the stroke endpoint accurately without interfering with normal travel, delivering a “feel‑free during normal travel, dependable at the limit” user experience.

This product is widely used in electromagnetic suspension assemblies, active dampers, and air suspension modules, suitable for premium passenger cars, off‑road SUVs, and heavy‑duty commercial vehicles. During manufacturing, each batch undergoes 100% dimensional inspection, hardness testing, impact energy absorption verification, and thermal cycling endurance tests, in compliance with IATF 16949 and ISO 26262 functional safety standards. With its simple yet robust mechanical principle, the retaining ring provides an indispensable safety redundancy for intelligent suspension systems, ensuring peace of mind even under the most demanding driving conditions.
