Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10 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 SGCJ250X75-10
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 10 mm external adjuster to shorten the extend stroke on site. Four steel tie rods clamp the aluminum barrel to the covers, and the G1 air port feeds the 50 mm piston rod. Because the nominal 75 mm stroke represents the maximum extension, you can fine-tune the end position down to 65 mm without changing the hardware. This translates to a safe working load of roughly 14726 N, or about 1251 kg lifted vertically with a 2:1 margin.
The unit features 60 mm adjustable air cushions at both ends to decelerate heavy loads smoothly. Note that TPU seals are not available on this 250 mm bore; it uses NBR packings, with a Viton H option for 0-150 C high-temperature environments. As a non-magnet SKU, it cannot accept CMSG, DMSG, or EMSG sensors without the -S variant. A plain pneumatic cylinder does not hold load on air loss, so fit an external rod lock or pilot-operated check valve if you need strict positioning.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10 Is Used
Press Tonnage Trimming
Apply 5006 kgf of maximum clamping force to seat heavy components, using the 10 mm adjuster to dial in the exact 65 to 75 mm extend position without re-piping the G1 air supply.
Heavy Pallet Stopping
Halt massive inbound loads using the 60 mm adjustable cushions. The external stop screw lets you set the contact point precisely on-site to match varying pallet depths.
Large Door Latching
Drive a robust 50 mm rod to throw heavy latches. The tie-rod construction handles the shock, while the end-position adjuster ensures the latch seats perfectly every time.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-10 the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, offering 24543 N push at 0.5 MPa compared to 15708 N on the 200 mm bore. If your application requires less force, dropping to the 200 mm bore saves space and air consumption. The 10 mm adjustable stroke window is ideal for sharing a single spare cylinder across multiple fixtures that require slightly different extend end positions. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since this is a non-magnet model, order the -S version if you require CMSG, DMSG, or EMSG position sensing. Even at 75 mm stroke, always guide the rod to prevent side-load wear.
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 SGCJ250X75-10 FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm rod. 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 -10 code indicates a 10 mm external adjuster window. The nominal 75 mm stroke is the maximum extension; you can shorten the extend stroke down to 65 mm on-site by turning the external stop screw. The retract end remains fixed, and this mechanism only sets the end position, it does not lock the load.
