Ultra-compact cylinder designed for space-constrained automation systems requiring precise linear motion. Features corrosion-resistant construction, dual anti-rotation grooves (prevents rod spinning), and a replaceable rod seal. The PTB series offers 30% smaller cross-section than standard cylinders while maintaining high repeatability positioning (±0.5mm). Requires filtered air (5-40μm) with ISO VG32 lubricant recommended.
- PCB handling robots in electronics assembly
- Medical device component positioning
- Photovoltaic panel sorting mechanisms
- Precision valve actuation in analytical instruments
- Compact clamping fixtures for CNC loading
Installation tips:
Lubricate piston rod monthly in high-cycle applications (>500k cycles/year).
Avoid side loads exceeding 3N·m. For vertical mounting, use pressure regulator
with locking mechanism to prevent unintended retraction.
