Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 500mm 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 SGCJ250X500-20
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy industrial tasks with ease. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1 air port feeds the 50 mm piston rod. It provides a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin.
The -20 code defines a 20 mm external adjuster window that shortens the extend stroke on site from the 500 mm maximum down to 480 mm, letting you fine-tune the end position without changing the cylinder itself. The retract end remains fixed. Note that TPU seals are not available on this 250 mm bore; it uses NBR buffer gaskets, with a Viton H option for 0-150 C high-heat environments. This plain SKU lacks a magnet and cannot take a sensor, whereas the -S variant supports CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20 Is Used
Heavy Pallet Lifting
Raises large loaded pallets, using the 20 mm adjuster to dial in the exact raise height and avoid overshooting the conveyor transfer point.
Hydraulic Press Clamping
Secures heavy steel plates during pressing operations, relying on the 24543 N push force and fine-tuning the clamp end position on site.
Large Mold Handling
Pushes substantial injection molds into the machine bed, trimming the extend stroke by up to 20 mm to seat the tooling without mechanical stops.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20 the Right Cylinder?
When sizing this unit against its neighbors, a 200 mm bore yields 15708 N push at 0.5 MPa, while this 250 mm bore provides 24543 N at the same pressure, sitting at the top of the range. The adjustable stroke is ideal for sharing a spare across stroke variants or making on-site end-position tweaks. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the stroke is 500 mm, you must use external guides to prevent rod bending and manage side loads. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for held 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 SGCJ250X500-20 FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It delivers 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 force of 5006 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke by up to 20 mm on site, giving a usable extend range of 480 to 500 mm while the nominal 500 mm remains the maximum. The retract end is fixed, and the adjuster only sets the end position; it does not lock the load.
