Compact Telescopic Hydraulic Cylinder Welded Body For Harvester

Telescopic Hydraulic Cylinder Product Description

Our Telescopic Hydraulic Cylinders are designed specifically for agricultural machinery such as Harvester. They feature long stroke, small size, and compact structure, enabling significant extension and retraction within limited installation space. They are ideal for situations requiring large strokes but with limited space, such as harvester header lifting, unloading canister extension, and reel adjustment.

We supply a wide range of Telescopic Hydraulic Cylinder for various applications, a multi-stage rod built of a series of nested steel tubes of progressively smaller diameter. This special design of hydraulic cylinder provides exceptional travel from a highly compact retracted length. Typically the collapsed length of a telescopic cylinder is 20% to 40% of the fully extended length, depending on the number of stages.

Runhe Hydraulics specializes in supplying hydraulic cylinders, gear pumps, gear motors, and accessories. Hydraulic cylinders can be customized to meet specific requirements, and chrome plating of piston rods is also available. Gear pumps, gear motors, and accessories are 100% compatible with Parker and other manufacturers, and can also be customized based on drawings.

Telescopic Hydraulic Cylinder Specification

Telescopic Hydraulic Cylinder Advantages

With a retractable length of only 20%-40% of the total stroke, it perfectly solves the problem of limited installation space. At the same time, it boasts strong thrust (the largest stage moves first, providing initial maximum force), and the speed increases progressively. Hard chrome-plated cylinder rods and corrosion-resistant seals ensure long-term operation in humid, dusty, and corrosive environments. Compared to ordinary single-stage cylinders, it is more suitable for heavy-duty, high-frequency cycling applications, and offers simple maintenance and high reliability.

Telescopic Hydraulic Cylinder Maintenance Guide

1. Keep the piston rod clean.
Before and after each use, wipe the exposed piston rod with a soft cloth to remove dust, dirt, and debris. Prevent contaminants from entering the seals, causing leaks or scratching the chrome plating.
2. Regularly check the hydraulic oil.
Keep the oil clean and free of impurities. Change the hydraulic oil every 500-1000 working hours or every six months, and clean the filter screen. Deteriorated oil will accelerate the aging of the seals.
3. Check for seals and leaks.
Regularly inspect the cylinder body, oil ports, and piston rod base for oil stains. If leaks or sluggish operation are found, replace the seals promptly to prevent small problems from developing into major malfunctions.
4. Avoid side loads and overloading.
Ensure the cylinder is under axial force during operation to avoid lateral forces that could cause bending or jamming. Strictly adhere to the rated load. Perform no-load bleed test before the first use or after maintenance.
