Precision-engineered ISO cylinder with integrated position sensing capability, featuring enhanced side load resistance through hexagonal piston rod design. The STC variant includes a built-in magnet for proximity sensor detection and dual cushioning adjustment screws for smooth end-of-stroke deceleration. Requires ISO VG32 hydraulic oil lubrication if used in high-cycle applications (>1 million cycles).
- Pick-and-place automation in electronic assembly lines
- Clamping fixtures for CNC machining centers
- Packaging machine ejector mechanisms
- Printing press paper feed systems
- Automotive welding jig positioning
Installation guidelines:
Maximum lateral load 35N, axial load 450N. For vertical mounting,
use counterbalance valves. Lubricate through air supply (ISO VG32
oil mist at 1 drop/m³). Magnetic sensors require 4-6mm gap adjustment.
