Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-50
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-50 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 SGCJ250X75-50
Delivering massive thrust, this 250 mm bore tie-rod cylinder pushes with 24543 N at 0.5 MPa. The G1 port feeds the 50 mm rod, yielding a safe working load of roughly 14726 N for real work. That translates to lifting about 1251 kg vertically with a 2:1 margin.
As a genuine ISO 15552 adjustable-stroke unit, four steel tie rods clamp the aluminum barrel for high rigidity. The external -50 mm adjuster lets you shorten the extend stroke on-site from the 75 mm maximum down to 25 mm without changing the cylinder. Note that TPU seals are unavailable for this bore, though Viton H raises the temperature range to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-50 Is Used
Heavy Press Toning
Dial in the exact 25 to 75 mm extend reach on-site to set precise pressing depth for thick industrial components.
Stubby Lift Stroke
Lift loads up to 1251 kg vertically with a 2:1 margin, tweaking the end position externally without swapping hardware.
Large Valve Seating
Shorten the extend stroke up to 50 mm to achieve perfect valve closure contact, avoiding over-travel damage.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-50 the Right Cylinder?
This 250 mm bore sits at the top edge of the SGCJ range, pushing 24543 N at 0.5 MPa; step down to a 200 mm bore for 15708 N if lower force is acceptable. The adjustable stroke is ideal when you need to fine-tune the extend end position on-site or share a spare across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this SKU lacks the -S magnet, it cannot take a CMSG/DMSG/EMSG sensor. Always guide the rod to prevent side-loading.
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 SGCJ250X75-50 FAQ
It pushes 24543 N and pulls 23562 N at 0.5 MPa. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical max is 5006 kgf at 1.0 MPa.
The nominal 75 mm extend stroke is the maximum. The external adjuster lets you shorten the extend end position by up to 50 mm on-site, giving a usable extend range of 25 to 75 mm. The retract end is fixed.
