Product Description

Suspention Cylinders

Product advantage
• The front suspension cylinder adopts a wide series of integral guide ring design with special structure and special material to ensure good guide support. At the same time, the piston rod adopts high hardenability and high strength materials, and special heat meter treatment is applied to ensure that the suspension cylinder has extremely high fatigue life under high frequency, high pressure and heavy load conditions.
• The suspension cylinder can be designed to match the stiffness and damping characteristics according to the customer's vehicle parameters.
• Selection of imported sealing ring to meet the harsh working conditions in mining areas.
• Steering cylinder can have built-in displacement sensor, real-time monitoring cylinder stroke.
• Can be customized according to customer needs design, provide integrated solutions.
