Airtac SGCD Dual Rod Cylinder SGCD200X300S
The AirTAC Airtac SGCD Dual Rod Cylinder SGCD200X300S is a genuine double acting, double rod ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø200mm bore and 300mm stroke, G3/4 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCD Dual Rod Cylinder SGCD200X300S
Delivering 15079 N of thrust in both directions at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a piston rod exiting both covers. The twin-rod architecture creates a symmetric load path that resists torsional twist, while the four steel tie rods clamping the aluminum barrel ensure high structural rigidity. It operates at 30-500 mm/s and uses a G3/4 air port.
With equal push and pull forces, the unit is rated for a safe working load of roughly 9047 N, translating to a vertical lift capacity of about 769 kg with a 2:1 margin. The built-in -S piston magnet supports CMSG, DMSG, and EMSG switches for precise end-position sensing. Standard TPU seals handle -20 to +70 C, though a Viton H option extends this range to 0-150 C.

Where the Airtac SGCD Dual Rod Cylinder SGCD200X300S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously using the symmetric output rods, ensuring perfectly timed material removal on both sides of a workpiece.
Anti-Rotation Transfer
Shifts heavy pallets laterally between conveyor lines where the dual-rod geometry prevents the load from twisting during rapid 30-500 mm/s transverse moves.
Symmetric Lift Fixture
Raises and lowers heavy 769 kg industrial containers with a balanced force profile, relying on the equal push and pull thrust to prevent sagging on the return stroke.
Is the Airtac SGCD Dual Rod Cylinder SGCD200X300S the Right Cylinder?
When sizing this double-acting unit, compare its 15079 N equal-both-ways force against the smaller 160 mm bore (9425 N) or the larger 250 mm bore (23562 N). Choose this twin-rod design when an application demands anti-rotation guidance, twin tooling driven from both ends, or a rear-mounted sensor cam. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S magnet enables CMSG/DMSG/EMSG sensor integration. Because the 300 mm stroke is relatively short, side-load stress is minimal, but external guide rails should still support the load to prevent binding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCD Dual Rod Cylinder SGCD200X300S FAQ
Because the rod passes through both covers, force is equal in both directions: 15079 N at 0.5 MPa and 21110 N at 0.7 MPa. The theoretical maximum is 3075 kgf at 1.0 MPa. This 200 mm bore model features a G3/4 air port and a 50 mm adjustable air cushion at each end.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position sensors. A plain pneumatic cylinder cannot hold a load without live air, as the cushion only decelerates near stroke end. For suspended loads, install an external rod lock or pilot-operated check valve to prevent drift.
