Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30S 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 SGCJ250X500-30S
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster to shorten the extend stroke on-site. The nominal 500 mm stroke serves as the maximum, while the -30 code designates a 30 mm shortening window, yielding a usable extend range of 470-500 mm for fine-tuning the end position without changing the hardware. Four steel tie rods clamp the aluminum barrel to the covers, and a G1 air port feeds the 50 mm piston rod.
Driven by a built-in piston magnet, the -S suffix enables direct mounting of CMSG, DMSG, or EMSG electronic switches for position sensing. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin. Note that TPU seals are unavailable for this 250 mm bore; standard NBR packings operate from -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30S Is Used
Heavy Pallet Upender
Provides the massive push force needed to rotate loaded pallets, using the 30 mm adjustable stroke window to fine-tune the exact tipping angle without repositioning the fixture.
Hydraulic Press Feed
Clamps large steel blanks prior to stamping, relying on the 60 mm adjustable air cushions to decelerate the heavy 50 mm rod smoothly at the end of the 500 mm travel.
Automated Storage Shuttle
Actuates a heavy-duty load shuttle in high-bay warehouses, using the built-in magnet and CMSG sensors to confirm retract and extend positions across the 470-500 mm range.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30S the Right Cylinder?
When sizing this actuator, the 250 mm bore sits at the top of the SGCJ range, generating 24543 N push and 23562 N pull at 0.5 MPa. Stepping down, a 200 mm bore yields 15708 N push, making this model the correct choice when those lower forces are insufficient. The adjustable stroke feature is highly beneficial for sharing a single spare cylinder across multiple stroke variants or dialing in exact end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a 500 mm stroke, external rod-end guides are strongly recommended to prevent side-load bending on the large 50 mm rod.
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 SGCJ250X500-30S FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it yields 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa. This 250 mm bore model uses a G1 air port and features a 50 mm piston rod with an M42x2.0 thread.
The -30 designates a 30 mm external adjuster window. The nominal 500 mm stroke is the maximum, but you can shorten the extend stroke on-site down to 470 mm to set the exact end position. The retract end remains fixed. This mechanism only sets travel limits; it does not lock the load, so an external rod lock or pilot-operated check valve is required to hold a load on air loss.
