Precision-engineered adjustable stroke cylinder featuring micrometer-style stroke adjustment with locking mechanism. The dual-cushion design minimizes end-impact noise (≤68 dB) while maintaining positioning accuracy (±0.3mm repeatability). Corrosion-resistant construction with IP54 protection rating makes it suitable for humid environments.
- Precision clamping fixtures in CNC machining centers
- Variable height positioning in automated packaging lines
- Pressure adjustment mechanisms in plastic injection molds
- Material handling systems requiring force-sensitive stops
- Semiconductor wafer processing equipment
Operational guidance:
Lubricate with ISO VG32 hydraulic oil monthly. Avoid side load exceeding 15% of max thrust.
For fine adjustment: Loosen lock nut, rotate adjustment screw (0.5mm per full turn), then re-tighten to 2.5N·m torque.
