Two cylinders can begin together and still become misaligned. Differences in load, friction, leakage and geometry can cause position errors even when the nominal flow split is equal.
Define the synchronization tolerance
State how much position difference the mechanism can tolerate and over what stroke. A loose coordination requirement differs from precision synchronization. Include unequal loading and the effect of one cylinder reaching an end stop first.
Compare possible control approaches
Flow division can help distribute delivery, but its accuracy and behavior depend on operating conditions. Mechanical coupling or position-feedback control may be needed for tighter coordination. Each approach introduces its own installation and failure considerations.
Plan recovery from mismatch
Determine how the system re-establishes alignment and what stops the machine if skew becomes excessive. Check pressure intensification, trapped volumes and structural loading. Do not add a simple tee connection and assume the two actuators will share flow equally.
Practical checklist
- Specify allowable position error under unequal loads.
- Identify the selected synchronization and sensing method.
- Define end-stop, fault and realignment behavior.
