The Ashun Machine Tool Counterweight Cylinder is a critical component developed for gravity balancing of the Z-axis in high-precision CNC machine tools. Working with an accumulator system, it perfectly offsets spindle head weight. Utilizing a special low-friction sealing system and high-precision machining, it eliminates "stick-slip" during low-speed operation, ensuring smooth and stable feeding,
Highlights
- Ultra-Low Friction Resistance: Employs customized low-friction seals and guide rings to ensure zero-error precision during micro-feeding.
- High Dynamic Response: Perfectly tracks the high-speed and high-frequency movements of servo motors without delay or lag.
- Zero Stick-Slip Phenomenon: Maintains smooth movement even at extremely low speeds, improving the surface finish of machined parts.
- Long-Lasting Wear Resistance: The piston rod surface undergoes special hardening and hard chrome plating, significantly enhancing wear resistance and rust prevention.
- Leak-Free Design: Optimized sealing structure ensures system cleanliness and pressure stability during long-stroke and continuous operations.

Technical Features
- The inner diameter of the cylinder tube undergoes precision honing to achieve an exceptionally high surface roughness (Ra) standard, reducing seal wear.
- Equipped with high-quality PTFE composite low-friction seals, offering high-temperature resistance and an extremely low friction coefficient.
- Can optionally integrate an anti-drop valve (safety valve) directly onto the cylinder body; instantly locks to prevent the spindle head from falling in case of pipe rupture.
- Offers various mounting options (e.g., flange, foot, trunnion), making it fully compatible with the designs of various machine tool brands.
- Features excellent lateral load-bearing capacity with an extended guide sleeve design, prolonging the overall service life of the hydraulic cylinder.
