Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-50S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-50S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 600mm stroke, G1 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 SGCJ200-250 Adjustable Cylinder SGCJ250X600-50S
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The external adjuster shortens the extend stroke on-site by up to 50 mm, letting you fine-tune the end position without changing the cylinder. The nominal 600 mm stroke remains the maximum, yielding a usable extend range of 550-600 mm while the retract end stays fixed.
Four steel tie rods clamp the aluminum barrel to the covers for high rigidity, and the G1 port handles massive airflow. It handles a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin. The built-in magnet supports CMSG/DMSG/EMSG sensors, and because this is a 250 mm bore, high-temperature Viton H seals are used instead of TPU.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-50S Is Used
Heavy Pallet Lifting
Lifts roughly 1251 kg vertically with a 2:1 safety margin, using the 50 mm adjuster to set precise pallet stop heights.
Hydraulic Press Damping
Provides 34360 N of extend force at 0.7 MPa for press operations, fine-tuning the crush depth within the 550-600 mm window.
Large Mold Clamping
Secures heavy industrial molds with a 60 mm adjustable air cushion, using the external stop to dial in exact clamping distance.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-50S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, pushing 24543 N at 0.5 MPa. If you step down to a 200 mm bore, thrust drops to 15708 N. The 50 mm adjustable window is ideal for sharing spares across stroke variants or dialing in end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches. Because the stroke is 600 mm, add external guide rails to prevent rod bending under side loads.
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 SGCJ200-250 Adjustable Cylinder SGCJ250X600-50S FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 550-600 mm from the 600 mm nominal maximum. The retract end is fixed. This stop only sets the end position; it does not hold the load on air loss.
