Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm 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 SGCJ250X800-10S
Delivering massive thrust for heavy industry, this 250 mm bore tie-rod actuator pushes with 24543 N and pulls with 23562 N at 0.5 MPa. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin. The G1 air port feeds the 50 mm piston rod, and a 60 mm adjustable air cushion decelerates the payload at both ends.
As a genuine ISO 15552 tie-rod cylinder, four steel rods clamp the aluminum barrel to the covers, ensuring rigid construction while matching standard mounting interface dimensions. The -10 code means an external adjuster can shorten the extend stroke on-site by up to 10 mm, giving a usable range of 790 to 800 mm for fine-tuning end positions without swapping the cylinder. Because this is a 250 bore, TPU seals are unavailable, but an NBR packing handles standard -20 to +70 C environments, and the -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10S Is Used
Heavy Pallet Lifting
Raises 1251 kg loaded pallets vertically with a 2:1 safety margin, using the 10 mm extend adjuster to fine-tune the exact raised height to meet a conveyor.
Press Ejection Station
Ejects heavy stamped parts using 24543 N of force, relying on the 60 mm adjustable cushions to decelerate the 800 mm travel smoothly before the retract end.
Large Mold Positioning
Extends an 800 mm stroke to push large tooling into a machine, using the external stop screw to dial in the final 10 mm of closure distance without reprogramming.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10S the Right Cylinder?
When sizing this actuator, stepping down to a 200 mm bore yields 15708 N of push force at 0.5 MPa, whereas this 250 mm bore provides 24543 N, and it maxes out at a 5006 kgf theoretical limit at 1.0 MPa. The 10 mm adjustable window is highly useful when you need to synchronize end positions across multiple fixtures or dial in a precise stop on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. The included -S magnet supports CMSG, DMSG and EMSG electronic or reed switches. Because the stroke is 800 mm, you must use external guide rails to prevent rod bending and absorb 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 SGCJ250X800-10S 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. This 250 mm bore cylinder uses a G1 air port and features a 50 mm rod with an M42x2.0 thread.
The 800 mm nominal stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, providing a usable extend range of 790 to 800 mm for precise end-position tuning. The retract end remains fixed. This stop only sets position; it does not hold the load on air loss, so you need an external rod lock or pilot-operated check valve for load holding.
