Hydraulic cylinder

pistondouble-actingsteel

Product Overview
The Cushioned Piston Cylinder is a specialized hydraulic actuator with integrated end-of-stroke cushioning. The built-in cushions decelerate the piston before it reaches the head or cap, preventing impact shock, reducing vibration and noise, and protecting connected equipment. Suitable for construction, agriculture, mining and general industrial machinery, this cylinder supports long service life and reduced maintenance downtime.

Model & Brand

• Model: Piston Type
• Brand: EAST AI

Advantages

• Shock Absorption: Built-in cushioning eliminates metal-to-metal impact at stroke ends.
• Extended Equipment Life: Protects hydraulic components from excessive stress and vibration.
• Noise Reduction: Smooth deceleration minimizes operational noise.
• Improved Productivity: Reduces downtime caused by maintenance and repairs.
• Energy Efficiency: Provides smoother operation, lowering system fatigue and energy loss.
• Versatility: Suitable for heavy machinery, precision equipment, and industrial automation.

Production Process

• Raw Material Selection: Premium alloy steel and seamless honed tubes are sourced to guarantee strength and purity.
• Machining of Cylinder Tube and Piston Rod: Precision CNC machining ensures tight tolerances and perfect fits.
• Heat Treatment: Critical parts undergo quenching, tempering, or induction hardening to achieve optimal hardness and wear resistance.
• Surface Treatment: Piston rods are hard chrome plated to resist corrosion and wear.
• Cushion Design Integration: Hydraulic cushions are built into both ends of the cylinder to absorb shock and ensure smooth deceleration.
• Assembly: High-quality seals, piston components, and cushion valves are assembled under cleanroom conditions.
• Testing: Each cylinder undergoes pressure, leakage, and functional tests to confirm compliance with international standards.
