Which outcome predominates when hydraulic actuator rod seals degrade in a robotic arm operating at high cycles?

A)Reduced positional accuracy from fluid bypass✓

B)Increased motor current due to higher load

C)Elevated oil temperature from increased friction

D)Pump cavitation from return line restriction

💡 Explanation

When rod seals degrade, internal leakage or fluid bypass occurs within the actuator because the high-pressure fluid leaks past the worn seals, decreasing the effective force and displacement. Therefore reduced positional accuracy directly results rather than current increase, overheating, or pump cavitation requiring distinct malfunctions.
