Description & Specifications

TYP STEEL LLC, the hydraulic cylinder tube manufacturer, manufactures a variety of hydraulic cylinder piston rod. It is a cylindrical rod that extends and retracts from the hydraulic cylinder. The piston rod is typically attached to the piston within the cylinder and transfers force from the hydraulic fluid to the external load. It plays a key role in converting fluid pressure into mechanical force, allowing the hydraulic system to perform various tasks such as lifting, pushing, or pulling.

FAQ about Honed Tube for Hydraulic Cylinder

What is a hydraulic cylinder piston?

A hydraulic cylinder piston is a component within a hydraulic cylinder that moves back and forth to convert fluid pressure into mechanical force.

Hydraulic cylinder pistons are often made of materials such as steel, aluminum, or other alloys, chosen for their strength, durability, and wear resistance.

The primary function of a hydraulic cylinder piston is to transfer hydraulic pressure into linear mechanical force to perform work in various applications.

Consider factors such as the required force, operating conditions, and system specifications. Consulting with hydraulic system designers or manufacturers is recommended for personalized guidance.

Common seals include O-rings, U-cups, and other types of hydraulic seals. The choice depends on factors such as pressure, temperature, and the specific requirements of the application.

What are the standard sizes for hydraulic cylinder pistons?

Hydraulic cylinder pistons come in various sizes, including different diameters and lengths. The size is determined by the specific requirements of the hydraulic system.

Yes, hydraulic cylinder pistons can often be customized based on specific application requirements, including size, material, and design features.

Regular inspection for wear, damage, or leaks is recommended. Lubrication and proper care contribute to the longevity and performance of hydraulic cylinder pistons.

Yes, safety is crucial when working with hydraulic systems. Follow proper maintenance procedures, use appropriate safety equipment, and adhere to industry safety guidelines.

The lifespan depends on factors such as usage, operating conditions, and maintenance practices. Regular inspections and proactive maintenance can extend the life of hydraulic cylinder pistons.
