Tie Rod Hydraulic Cylinder
Tie Rod Hydraulic Cylinder
1. Introduction
A Tie Rod Hydraulic Cylinder is a type of linear actuator that uses hydraulic fluid to create force and motion in a straight line. It is uniquely built with steel tie rods that run the length of the cylinder body, holding the end caps tightly in place. These cylinders are common in industrial machines, construction equipment, and automation systems due to their ease of maintenance, high durability, and replaceable components.
Think of it as a robust, repair-friendly powerhouse used to push, pull, lift, or press heavy loads using hydraulic pressure.
2. Key Features

7. FAQs (Frequently Asked Questions)
What pressure can a tie rod cylinder handle?
Typically from 1500 PSI to 3000 PSI, depending on size and application.
Can I use it in outdoor environments?
Yes, but consider a corrosion-resistant coating and weatherproof seals.
Are tie rod cylinders repairable?
Absolutely. They are designed for disassembly, making seal replacement easy.
What's the difference between a tie rod and welded cylinder?
Tie rod cylinders can be opened and serviced; welded cylinders are sealed and more compact but harder to repair.
Is it available in custom sizes?
Yes, most manufacturers offer custom bore, stroke, and mounting options.
