Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-10
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-10 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 SGCJ250X500-10
Delivering massive thrust, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. The G1 ported body uses four steel tie rods to clamp the aluminium barrel, ensuring rigid high-force operation. It handles a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 margin.
The -10 code defines a 10 mm external adjuster window that shortens the extend stroke on-site from the 500 mm maximum down to 490 mm. This lets you fine-tune the end position without changing the cylinder itself. The retract end remains fixed. Note that TPU seals are unavailable for this 250 mm bore; it uses NBR packing, though a Viton H option extends the temperature range to 0-150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-10 Is Used
Press Stroke Tuning
Use the 10 mm extend adjuster to dial in the exact 490-500 mm end position for heavy stamping presses without machining new spacers.
Heavy Pallet Lifting
Lifts roughly 1251 kg vertically with a 2:1 safety margin, ideal for raising massive loaded pallets in automated warehouse dispatch bays.
Mold Clamping Fixture
Clamps large injection molds using 24543 N of force at 0.5 MPa, relying on the rigid tie-rod frame to resist deflection under high pressure.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-10 the Right Cylinder?
When sizing, the 160 mm bore offers 10053 N push at 0.5 MPa, while this 250 mm bore tops out at 24543 N, defining the upper edge of the range. The 10 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a no-S SKU, it cannot take a magnetic switch; you need the -S variant for CMSG/DMSG/EMSG sensors. Finally, at 500 mm stroke, large-bore rods need external guide support to prevent side-load bending.
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 SGCJ250X500-10 FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum is 5006 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 490-500 mm. The nominal 500 mm is the maximum, and the retract end is fixed. This mechanism sets the end position and is not a load lock.
