Ultra-compact cylinder featuring a unique stroke adjustment mechanism with ±1mm precision. The dual-chamber cushion design minimizes end-impact noise below 65dB. Corrosion-resistant chromium-plated rod and IP54-rated construction ensure reliability in humid environments. Requires 5μm filtered air with ≤1mg/m³ oil content.
- Precision positioning in SMT equipment
- Semiconductor wafer handling systems
- Pharmaceutical blister packaging machines
- Robotic end-effector tool changers
- Automated optical inspection (AOI) stages
Installation guidelines:
Maintain ≤0.1mm/m alignment tolerance during mounting. For vertical installations,
use speed controller (ASC-06) to prevent piston free-fall. Allow 20mm clearance
behind cushion screws for adjustment tools.
