When standard hydraulic cylinders are no longer available — discontinued, non-standard, or simply impossible to source — ProHydraulics engineers the solution. We manufacture custom hydraulic cylinders to your exact drawings and specifications, delivering to industrial clients in 15+ countries across Europe, CIS, and beyond. From a pilot batch of 2 units to full production line replacement — we deliver what others can't.

Our engineering approach focuses on durability, precision manufacturing, and long service life under extreme operating conditions. Every cylinder is produced to exact client specifications — with full technical support from drawing review to final delivery.

Types of Hydraulic Cylinders

ProHydraulics supplies a wide range of hydraulic cylinders for industrial equipment.

Single-Acting Hydraulic Cylinders

Used in applications where hydraulic force is required in one direction only. Commonly used in lifting systems and heavy machinery.

Double-Acting Hydraulic Cylinders

The most common industrial solution where controlled force and movement are required in both directions.

Telescopic Hydraulic Cylinders

Multi-stage cylinders designed to achieve long strokes within limited installation space.

Heavy-Duty Hydraulic Cylinders

Reinforced cylinders designed for continuous operation under high loads and demanding industrial environments.

Large Hydraulic Cylinders

Large-bore cylinders used in steel mills, mining equipment, hydropower plants, and heavy machinery.

Technical Specifications

Hydraulic cylinders supplied by ProHydraulics are manufactured according to the technical requirements of each project.

Parameter Range

• Piston diameter 25 – 1000 mm
• Rod diameter 8 – 300 mm
• Stroke length up to 15 000 mm
• Total cylinder length up to 32 m
• Working pressure 160 – 300 bar
• Maximum pressure up to 500 bar
• Telescopic cylinder stages up to 7 stages

Each cylinder is engineered according to application requirements, load calculations, and operating conditions.

Materials and Manufacturing

Hydraulic cylinders are manufactured using high-strength industrial materials to ensure structural reliability and long service life.

Typical materials include:

• CK45 steel

• E355 / ST52 structural steel

• Steel 20 / Steel 45

• Stainless steel for corrosive environments

Cylinder components are machined using CNC equipment and undergo strict dimensional inspection during production.

Surface Treatment and Rod Protection

To ensure durability in aggressive environments, piston rods and components can be treated using advanced surface technologies:

• Hard chrome plating

• Nickel-chrome coating

• Ceramic carbide coating

• Corrosion-resistant coatings

• Chrome plating thickness can reach up to 80 microns, improving wear resistance and corrosion protection.

Sealing Systems

Reliable sealing systems are essential for hydraulic cylinder performance and longevity.

ProHydraulics cylinders can be equipped with sealing solutions from leading international manufacturers such as:

• ProHydraulics

• Hallite

• Trelleborg

• NOK

• SKF

Seal systems are selected according to operating pressure, temperature, movement speed, and environmental conditions.

Precision and Quality Standards

Manufacturing tolerances are maintained according to industrial standards to ensure smooth and reliable cylinder operation.

• Component Precision
• Cylinder tube H8
• Piston rod f7

All components undergo dimensional inspection and quality verification during manufacturing.

Testing and Quality Control

Each hydraulic cylinder undergoes comprehensive quality control procedures including:

• pressure testing

• leak testing

• dimensional inspection

• functional movement testing

• load verification

Test pressure is typically 1.5–2 times higher than the working pressure to ensure operational safety and reliability.

Hydraulic Cylinder Selection Guide

Selecting the correct hydraulic cylinder is critical for safe and efficient machine operation.

The required cylinder force depends on hydraulic pressure and piston area.

F = P \times A

Where:

F – cylinder force

P – hydraulic pressure

A – piston area

Larger piston diameters generate greater force at the same system pressure.

Other important parameters include:

• stroke length

• mounting configuration

• operating pressure

• environmental conditions

• material selection.

Mounting Options

Hydraulic cylinders can be supplied with a wide range of mounting configurations depending on machine design.

Typical mounting types include:

• Clevis mounting

• Trunnion mounting

• Flange mounting

• Foot mounting

• Spherical bearing mounting

Custom mounting solutions can also be developed for specialized industrial equipment.

Optional Components and Accessories

To meet project requirements, cylinders can be equipped with additional components:

• Position sensors

• Limit switches

• Linear displacement sensors

• Protective bellows

• Rod locking mechanisms

• Special coatings for marine environments

These features allow integration into modern automated and monitored industrial systems.

Typical Hydraulic Cylinder Applications

Hydraulic cylinders supplied by ProHydraulics are widely used in heavy industrial equipment where reliable linear force and motion control are required.

Steel and Metallurgical Plants

Hydraulic cylinders are used in:

• rolling mills

• furnace doors

• continuous casting machines

• ladle handling equipment

• slab pushing systems

These applications require cylinders capable of operating under high loads and extreme temperatures.

Mining Equipment

Mining machinery requires durable cylinders capable of working in abrasive and harsh environments.

Typical applications include:

• drilling rigs

• crushing equipment

• excavators and loaders

• material handling systems

Hydropower Plants

Hydraulic cylinders are essential for hydropower infrastructure such as:

• dam gates

• spillway gates

• turbine control mechanisms

• hydraulic lifting systems

These cylinders must provide reliable performance in wet and corrosive environments.

Heavy Industrial Machinery

Hydraulic cylinders are widely used in:

• industrial presses

• lifting platforms

• automated production equipment

• special heavy-duty machinery.

Replacement Hydraulic Cylinders

ProHydraulics also supplies replacement cylinders for existing industrial equipment.

Our engineers can reproduce cylinders based on:

• original technical drawings

• worn or damaged cylinders

• dimensional measurements

• client specifications

This service allows companies to restore equipment performance without redesigning entire hydraulic systems.
