Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 350mm 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 SGCJ250X350-50
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 50 mm external adjuster to fine-tune the extend end position on site. The nominal 350 mm stroke serves as the maximum travel, allowing you to shorten the forward movement down to 300 mm without swapping the actuator. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity, while the G1 port handles the high air volume required for the 250 mm bore.
In real work it handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety 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. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors without the -S variant. The adjustable air cushion is 60 mm at each end to decelerate heavy loads smoothly.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50 Is Used
Heavy Pallet Lifting
Raises 1251 kg loaded pallets vertically with a 2:1 safety margin, using the 50 mm adjuster to set the exact lift height without repositioning the cylinder.
Hydraulic Press Tonnage
Provides 24543 N of pressing force at 0.5 MPa for heavy-duty forming, using the 60 mm adjustable cushion to absorb the shock at the end of the 350 mm stroke.
Large Mold Clamping
Secures large industrial molds by extending the full 350 mm stroke, with the external stop screw available to shorten the clamp reach by up to 50 mm for varied mold sizes.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50 the Right Cylinder?
When sizing this 250 mm bore actuator, stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while this model reaches 24543 N. If you need even more power, there is no larger standard SGCJ bore, making this the top edge for the series. The 50 mm extend-shortening window is ideal for sharing a single spare cylinder across multiple stroke variants or dialing in a precise end position during machine commissioning. You can mount it via FA, LB, TC, FTC, TCM1 or TCM2 brackets using the ISO 15552 mounting interface. Since the 350 mm stroke is below the 500 mm threshold, side-load guide requirements are relaxed, but heavy 250 mm bore loads still demand proper guiding. Remember that this non-magnet SKU cannot host position sensors.
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 SGCJ250X350-50 FAQ
At 0.5 MPa it delivers 24543 N push and 23562 N pull. 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. It uses a G1 air port and a 60 mm adjustable cushion at both ends.
The external adjuster lets you shorten the extend stroke by up to 50 mm on site, meaning the usable forward travel is 300 to 350 mm. The nominal 350 mm stroke is the maximum. The retract end is fixed. This mechanism only sets the end position and does not lock the load; a separate rod lock or pilot-operated check valve is required to hold a load on air loss.
