Product advantages

1.Bidirectional balanced power

• Both the piston chamber and the piston rod chamber can be filled with hydraulic oil, enabling both extension and retraction to be driven actively in both directions. This breaks through the limitation of single-acting cylinders that rely on springs or loads for return.

• Customer Value: Suitable for scenarios that require precise control of reciprocating motion, such as mold closing in injection molding machines and control of the boom of excavators. The operational efficiency can be increased by more than 30%.

2. Long-lasting and durable structural design

• The cylinder is made of cold-drawn alloy steel (with hard chrome plating on the surface, thickness ≥ 25μm), and the piston rod undergoes high-frequency quenching treatment (HRC ≥ 55), resulting in a 50% improvement in wear resistance and corrosion resistance.

• Customer Value: With a lifespan of over 10,000 hours in harsh environments such as mines and ports, it reduces the frequency of replacements and maintenance costs.

3. Precise and smooth motion control

• Built-in low-friction seals, combined with precise guide sleeves, have a friction coefficient of ≤ 0.05, without any crawling phenomenon.

• Customer Value: Applicable to high-precision equipment such as machine tools and presses, with the positioning error controlled within ±0.5mm.

4. Flexible customized configuration

• Supports customized installation forms (ear ring/flange/hinge shaft), stroke (50mm - 5000mm), oil port size (M18×1.5 to SAE 12), with the maximum pressure resistance up to 35MPa.

• Customer Value: Perfectly compatible with customized equipment layouts, shortening the equipment development cycle.
