Even small dimensional deviations can lead to major system risks.
Understanding stroke limit deviation is critical for precision, safety, and equipment reliability.
Stroke limit deviation refers to the difference between the:
Designed (nominal) stroke, and Actual maximum extension or retraction stroke of a hydraulic cylinder
In simple terms: It defines how accurately a cylinder reaches its intended end position.
Stroke deviation can be caused by:
• Manufacturing tolerances (tube length, piston position)
• Cushioning structure variations
• Seal compression differences
• Assembly accuracy
• Thermal expansion during operation
Even high-quality cylinders have controlled allowable deviation ranges.
In precision systems (automation, lifting platforms), stroke deviation directly affects final positioning accuracy
Excess stroke may cause: Structural collision / Over-extension damage / Cylinder bottoming impact
Insufficient stroke may lead to: Incomplete operation / Uneven load distribution / System instability
In multi-cylinder systems, stroke mismatch can cause synchronization failure and uneven motion.
