Stick-slip phenomenon occurs when static friction exceeds kinetic friction in low-speed applications, causing cylinders to alternate between sticking (zero motion) and slipping (sudden acceleration), with the severity determined by the friction differential ratio, seal design, load characteristics, and operating pressure, making proper seal selection and system design critical for achieving smooth low-speed motion.

Self-lubricating seals incorporate embedded solid lubricants like PTFE or graphite directly into the seal material, eliminating external lubrication requirements while providing superior wear resistance, extended service life up to 10 million cycles, and contamination-free operation ideal for food processing, pharmaceuticals, and precision manufacturing.

Meter-out circuits use precision flow control valves on the exhaust side to create back-pressure that smoothly regulates cylinder speed throughout the entire stroke – providing consistent, adjustable motion control with excellent load handling and superior positioning accuracy for demanding industrial applications.
