Product Introduction

Core Definition: Single Acting Hollow Piston Cylinders are lightweight hydraulic actuators that use hydraulic oil as the transmission medium, adopting a single-acting drive and hollow piston structure, mainly used in various precision operation scenarios requiring one-way thrust or tension, distinguished from conventional hydraulic jacks by their unique structural design.

Working Principle: This product relies on hydraulic oil acting on one side of the piston to generate one-way driving force, pushing the piston to extend for operation, and the return stroke is reset by the built-in spring or the weight of the load itself, with a simple structure and convenient operation, without the need for complex two-way hydraulic control circuits.

Basic Specifications: The rated load capacity of Single Acting Hollow Piston Cylinders ranges from 5 tons to 150 tons, with an effective stroke of 6mm to 64mm and a maximum working pressure of up to 70MPa. The through-hole design in the center of the piston allows cables, shafts, pull rods and other components to pass through, adapting to various special operation needs.

Product Advantages

Compact Structure and Strong Portability: The hollow piston design reduces material usage while ensuring load-bearing strength, with a small overall volume and light weight. Compared with solid piston jacks of the same tonnage, it is easier to carry and operate, especially suitable for narrow spaces, high-altitude or field mobile operation scenarios, greatly improving operation flexibility.

Diversified Functions and Wide Adaptability: The through-hole design of the hollow piston enables it to have multiple functions such as lifting, stretching and extrusion, which can complete special operations such as bearing disassembly, bolt tensioning and component positioning. It can not only be used for conventional lifting, but also penetrate rods through the central through-hole to achieve traction operations, adapting to the diverse needs of different industries.

Durable, Reliable and Convenient to Maintain: The cylinder body is made of high-strength steel, the piston surface is chrome-plated, and the cylinder surface is treated with baking paint, which effectively improves corrosion resistance and wear resistance; the built-in dust ring reduces the entry of impurities and extends the service life. Moreover, it has a simple structure and is easy to disassemble, and daily maintenance only needs to regularly check the seals and hydraulic oil, reducing maintenance costs.

Product Applications

Industrial Equipment Maintenance Field: Widely used in the maintenance of heavy machinery, machine tools, motors and other equipment, it can be used for bearing disassembly, gear installation, shaft component calibration, etc., especially suitable for precision operations in narrow spaces inside equipment, solving the operation problems that conventional tools cannot reach.

Construction and Bridge Engineering Field: Used in bridge prestress tensioning, steel structure installation, foundation pit support and other operations, steel strands are inserted through the through-hole of the hollow piston to accurately apply prestress. It can also be used for the lifting and positioning of building components, ensuring the accuracy and safety of engineering construction.

Other Special Scenarios: Adapt to wind power equipment maintenance, ship manufacturing, precision component testing and other fields, and can complete operations such as wind turbine blade installation, ship section alignment, and component tensile strength testing. With its compact structure and precise driving force, it meets the operation needs of various complex working conditions.
