Key Features:

Superior Material Strength: Crafted from 45# steel (equivalent to CK45/SAE1045), the rshock absorber piston rod undergoes rigorous heat treatment (including induction hardening and quenching & tempering) to achieve a tensile strength of ≥610 N/mm² and yield strength of ≥355 N/mm².

Advanced Hard Chrome Plating: The surface is electroplated with a dense chromium layer (20–30 microns thick). This enhances wear resistance, extends component lifespan by up to 40% compared to unplated alternatives.

Precision Engineering: With a diameter tolerance of ISO f7, straightness ≤0.2 mm/m, and surface roughness Ra ≤0.2 µm, the rod ensures seamless integration with shock absorbers, minimizing vibration and noise.

Why Choose Our Shock Absorber Piston Rod?

Longevity: The chrome plating and QPQ process prevent premature wear and hydrogen embrittlement, ensuring reliability under cyclic loads.

Quality Assurance: Every shock absorber piston rod undergoes 100% inspection using measuring tools, including hardness tests, dimensional checks, and salt spray validation.

Global Compliance: Meets SGS standards for international deployments.

Shock Absorber Piston Rod Applications:

Automotive: Shock absorbers, struts, and suspension systems for cars, trucks, and motorcycles.

Custom Solutions: OEM support for specialized designs, including hollow shafts and tapered ends.
