Ultra-compact square-profile cylinder with integrated mounting slots, optimized for space-constrained automation setups. Features corrosion-resistant construction and dual-purpose magnetic ring (SR suffix) for position sensing compatibility. Requires filtered air (5-40μm) with ISO VG32 oil mist lubrication recommended for heavy cycling.
- Precision fixture clamping in CNC tool changers
- Paper feed mechanisms in office automation equipment
- Valve actuation in semiconductor wafer handling
- Medical device component positioning systems
- Robotic end-effector ejection mechanisms
Installation note:
Align cylinder axis within 0.2mm perpendicularity tolerance. For vertical downward thrust applications,
increase supply pressure by 0.05MPa to compensate for spring force. Magnetic sensor installation requires
0.5-1.0mm gap adjustment using included shim washers.
