Cylinders are said to be synchronized when they __________.

• A. Use PCFC valves
• B. Finish their strokes simultaneously
• C. Operate at the same pressure
• D. Are the same size

Answer: (B)

Synchronization means they finish their strokes simultaneously. When several cylinders move a single load, finishing together keeps the load level and the mechanism moving in a parallel path; if one cylinder finishes first, it can cause tilting, binding, or uneven force distribution as the others catch up. Because actual speed is affected by factors like friction, seal wear, rod-side losses, and different loads, simply using the same bore size or the same supply pressure does not guarantee synchrony. Achieving true synchronization requires coordinating the hydraulic flow so each cylinder travels at the same rate, or using linkages or control systems that match their motion rather than relying on sizes or pressure alone.
