Features Of Hollow Hydraulic Rod

1. Material Selection

45# steel is commonly used for shock absorbers, while 40Cr is chosen for heavier loads and impact resistance.

2. Advanced Surface Treatments

Hard Chrome Plating: Delivers a thickness of 15–25μm, providing a surface hardness of ≥800 HV.

QPQ Treatment: Hollow hydraulic rod with 120+ hours salt spray tested and surface hardness without compromising the rod’s core toughness.

4. Precision Machining & Quality

Achieves tight tolerances (ISO f7/h8) and a ultra-smooth surface finish (Ra ≤0.2μm). This precision ensures perfect sealing with gas spring components, reduces friction, and extends seal life.

5. Corrosion Resistance

Chrome plating or QPQ treatment provides protection against rust, chemicals, and humidity, which is essential for outdoor or high-moisture environments.

Hollow Hydraulic Rod Applications

Automotive: Trunk lids, hood supports, and seat adjustment mechanisms.

Furniture: Office chairs, medical beds, adjustable desks, and cabinet lifting systems.

Customization Options

Dimensions: Hollow hydraulic rod diameters from Ø6–30mm and lengths up to 1000mm (custom orders for larger sizes available).

Material Grade: Choice of 45# steel, 40Cr, 35# steel, or stainless steel (304/316) to match specific strength and corrosion resistance needs.

Surface Finish: Hard chrome plating (standard or heavy-duty thickness) or QPQ treatment, with optional polished surfaces for specialized sealing requirements.

End Configurations: Threading, machining, or special end forms to fit unique assembly designs.
