Order now — Atlantechdrives provides you the 84.400.01, a high-performance pneumatic actuator component engineered by Kuhnke for precision linear motion in automated production lines. This 84-series part is essential for high-cycle applications where repeatability and mechanical durability are critical for operational uptime.
What Is the 84.400.01?
The 84.400.01 is a professional-grade pneumatic cylinder or actuator module from Kuhnke, designed to deliver decisive force in a compact form factor. Built with a hard-anodized aluminum body and a precision-ground stainless steel rod, this actuator is resistant to the corrosive effects of industrial moisture and oils. The internal design features low-friction seals that ensure a smooth transition even at very low speeds, preventing the «stick-slip» effect common in lower-quality actuators. The 84.400.01 is optimized for high-speed operation, featuring integrated cushioning to absorb kinetic energy at the end of each stroke, which prevents mechanical shock and extends the life of the machine frame. Characterized by its high volumetric efficiency, it allows for rapid extension and retraction cycles, making it an ideal choice for pick-and-place robots, automated sorting gates, and material handling jigs. Kuhnke’s engineering ensures that the 84.400.01 operates with high positional accuracy over millions of cycles, providing a reliable and low-maintenance solution for engineers looking to optimize throughput in 24/7 manufacturing environments.

Applications and System Architecture
The 84.400.01 is predominantly used in the semiconductor, pharmaceutical, and automotive industries. In a typical system architecture, it is controlled by a 5/2-way directional valve that manages the air distribution to the cylinder chambers. Its design allows for the easy addition of magnetic proximity sensors, enabling the PLC to receive real-time feedback on the actuator’s position. This is vital for complex, synchronized movements where a machine sequence must only continue once the 84.400.01 has fully extended or retracted. Its robust construction allows it to be mounted in any orientation, providing mechanical designers with significant flexibility in tight machine spaces where larger cylinders would be impractical.
Expert Tips
When installing the 84.400.01, it is critical to ensure that the piston rod is perfectly aligned with the load. Side-loading is the primary cause of premature seal failure and rod scoring in pneumatic actuators. We recommend using a spherical rod eye or a flexible coupling if perfect alignment cannot be guaranteed. Additionally, always check that the pneumatic lines are purged of debris before connection; even small metal fragments can score the internal barrel, leading to bypass leakage that reduces the actuator’s output force. Regular inspection of the rod seals for signs of dry-running is also advised; a light mist of pneumatic-grade lubricant can extend seal life in extremely dry air systems.
Frequently Asked Questions
Q: Does the 84.400.01 include integrated end-position cushioning?
A: Yes, most 84-series modules feature elastic end-cushioning as standard to prevent mechanical damage during high-speed operation; check the datasheet for adjustable options.
Q: Is the 84.400.01 suitable for cleanroom environments?
A: Due to its anodized finish and high-quality seals, it is often used in cleanroom-adjacent applications; however, for full cleanroom certification, verify the specific emission ratings with our technical team.
