Ultra-compact cylinder featuring precision-adjustable cushioning with dual shock absorption stages. The 360° rotatable buffer valve enables fine-tuning of end-position damping without disassembly. Anodized barrel surface resists chemical corrosion and mechanical wear, while the chrome-plated piston rod ensures smooth operation in high-cycle applications (up to 1.5 million cycles at rated load).
- PCB handling robots in electronics assembly
- Dispensing valve actuators in pharmaceutical packaging
- Precision clamping devices for CNC fixtures
- Automated microscope stage positioning
- Compact sorting gates in logistics systems
Installation tip:
For vertical mounting, install with rod facing downward. Use locknuts on both ends of cushion screws after adjustment. Lubricate with ISO VG32 hydraulic oil for initial operation.
Critical note:
Avoid side load exceeding 15N. When stroke <20mm, disable cushion mechanism to prevent internal collision. Maximum lateral misalignment: ±0.5°.
