The Difference between Unidirectional Hydraulic Cylinders And Bidirectional Cylinders

Differences in Operating Principles

Unidirectional hydraulic cylinders rely on hydraulic pressure to push the piston, and resetting is usually accomplished by springs or gravity. Bidirectional hydraulic cylinders, on the other hand, can push and pull back the piston by hydraulic pressure, which is suitable for work scenarios that require reciprocating action.

Differences in Applicable Scenarios

Unidirectional hydraulic cylinders are suitable for lifting equipment, such as automobile tailgates or truck tipping devices, due to their simplicity. Bidirectional hydraulic cylinders are suitable for complex operations, such as industrial robots, construction cranes and other scenes that require multi-directional movements.

Structure and Cost Comparison

Unidirectional hydraulic cylinders are simple in design, low cost and low maintenance. Bidirectional hydraulic cylinders are powerful, but the structure is complex and expensive, suitable for users with higher budgets and complex needs.
