Hydraulic cylinders are mechanical actuators that provide unidirectional force through a unidirectional stroke, using hydraulic fluid. They are widely used in various industries due to their ability to generate significant force and handle heavy loads.
The most commonly used material for seals in hydraulic cylinders is nitrile rubber (NBR). Learn more in our guide to hydraulic seals.
- Hydraulic Pump: Converts mechanical energy into hydraulic energy.
- Hydraulic Fluid: Medium for transmitting power (usually oil-based).
- Valves: Control the flow, direction, and pressure of the fluid.
- Hydraulic Cylinders: Actuators that perform work by converting hydraulic energy into mechanical force.
- Reservoir: Stores hydraulic fluid.
- Filters: Remove contaminants to maintain system efficiency.
- Hoses and Pipes: Transport hydraulic fluid between components.
- High power density (compact systems can generate large forces).
- Smooth and precise control.
- Ability to operate under heavy loads and extreme conditions.
- Flexibility in application across industries.

- Contamination: Dirt or water in the fluid.
- Overheating: Excessive temperature reduces fluid viscosity.
- Seal Failure: Leads to leaks or loss of pressure.
- Improper Maintenance: Neglecting fluid changes, filter replacements, or inspections.
- Load capacity: Match the cylinder's capacity to the required force.
- Stroke length: Choose based on the required movement range.
- Operating pressure: Ensure it matches the system's pressure rating.
- Mounting style: Based on the application (e.g., clevis, flange, trunnion).
