Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 75mm 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 SGCJ250X75-10S
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that shortens the extend stroke on-site by up to 10 mm. The nominal 75 mm stroke serves as the maximum travel, yielding a usable 65 to 75 mm range, while the retract end remains fixed. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity. Equipped with a G1 air port, a 50 mm rod, and a built-in magnet for CMSG/DMSG/EMSG sensors, it handles a safe working load of roughly 14726 N or about 1251 kg lifted vertically with a 2:1 margin.
Because this is a 250 mm bore, TPU seals are not available; instead it uses NBR packings with a Viton H option for 0 to 150 C environments. The 60 mm adjustable air cushions at each end absorb kinetic energy near stroke end. Note that the cushion only decelerates the piston and does not lock the load on air loss. For holding a suspended load, you must fit an external rod lock or a pilot-operated check valve.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10S Is Used
Heavy Pallet Forming
Apply 24543 N of push at 0.5 MPa to compact heavy pallets, using the 10 mm adjuster to dial in the exact crush distance.
High-Flow Actuation
Drive large-bore process valves where the 65 to 75 mm travel window must be precisely set on-site to seat the gate without mechanical binding.
Industrial Pressing
Execute heavy-duty pressing tasks, relying on the four tie rods for rigidity and the 60 mm cushions to absorb the 5006 kgf peak impact safely.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10S the Right Cylinder?
When sizing this unit, stepping down to a 200 mm bore yields 15708 N push at 0.5 MPa, while this 250 mm bore tops the range at 24543 N. The 10 mm adjustable window is ideal for fine-tuning the end position on-site without swapping the cylinder, letting you standardize spares across slightly different stroke variants. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix confirms the piston magnet is present for CMSG/DMSG/EMSG switches. Even at 75 mm stroke, always guide the rod to prevent side loads from damaging the front cover.
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 SGCJ250X75-10S FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm piston rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external adjuster allows you to shorten the extend stroke by up to 10 mm on-site. With a nominal 75 mm maximum stroke, the usable extend range is 65 to 75 mm. The retract end is fixed, and the stop screw sets the end position but does not function as a load lock.
