Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-75S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-75S 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 SGCJ250X75-75S
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 75 mm. The nominal 75 mm stroke represents the maximum travel, letting you fine-tune the end position without physically swapping the actuator. It handles a safe working load of roughly 14726 N, which equates to lifting about 1251 kg vertically with a 2:1 margin.
Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the G1 port feeds the 50 mm piston rod. Because this is a 250 mm bore, TPU seals are unavailable; standard NBR packings handle the -20 to +70 C range, while a Viton H option extends heat resistance to 150 C. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG position switches.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-75S Is Used
Press Stroke Tuning
Dial in the exact 0-75 mm extend contact point on a heavy stamping or riveting press without removing the 250 mm bore cylinder from the fixture.
Heavy Spotting
Lower massive molds or platens with 24543 N of force, relying on the external stop screw to set a precise, repeatable seating depth.
Pallet Stop Adjustment
Fine-tune the stopping distance for varying pallet sizes on a high-force conveyor line by simply turning the on-site adjuster.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-75S the Right Cylinder?
When sizing this unit, stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while stepping up is impossible as 250 mm is the largest SGCJ option. The 75 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants, fine-tuning end positions on-site, or perfectly timing a press contact. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet supports reed and electronic sensors. Even at a short 75 mm stroke, always guide the rod end to absorb side loads and 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 SGCJ200-250 Adjustable Cylinder SGCJ250X75-75S FAQ
This 250 mm bore cylinder uses a G1 air port and a 50 mm rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke by up to 75 mm directly on-site. The nominal 75 mm stroke is the maximum travel, so the usable extend range is 0-75 mm, while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
