The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X400-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 400mm 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.
Delivering massive thrust, this 250 mm bore tie-rod actuator pushes with 24543 N at 0.5 MPa. It is a genuine ISO 15552 cylinder, dimensionally interchangeable per the standard mounting interface to drop into existing large-bore fixtures. Four steel tie rods clamp the aluminium barrel to the covers, and a two-way piston seal ensures reliable bidirectional control. The G1 air port handles the high volume needed for this bore size.
The -10 code defines a 10 mm external adjuster window, letting you shorten the extend stroke on site from the 400 mm maximum down to 390 mm without changing the cylinder itself. This on-site fine-tuning of the end position is perfect for dialing in a shared spare across slightly different stroke variants. Because this is a 250 bore, TPU seals are not available; standard NBR packing handles the -20 to +70 C range, with a Viton H option for 0-150 C. This SKU lacks a magnet, so it cannot take a magnetic switch without specifying the -S variant for CMSG/DMSG/EMSG sensors.

| Max (@1.0 MPa) | 5006 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

SGC-family variants: SGC (double acting), SGCD (double rod), SGCJ (adjustable stroke). Mounting: LB / FA / FB / CA / CB / CR / TC / FTC / TCM1 / TCM2. Seals: TPU (blank) / Viton H / NBR N.
Lifts roughly 1251 kg vertically with a 2:1 safety margin, ideal for raising loaded pallets in automated distribution hubs where the 10 mm stroke adjuster dials in exact upper stops.
Provides a safe working load of about 14726 N for assembly presses, using the external adjuster to fine-tune the 390-400 mm extend position without swapping mechanical stops.
Clamps heavy steel workpieces in stamping lines, using the G1 port for high flow and the 60 mm adjustable air cushions to decelerate the massive 250 mm piston smoothly.
Size this 250 mm bore against the 200 mm option, which provides 15708 N push at 0.5 MPa. If you need more power, this 250 mm model is the top end, yielding 34360 N at 0.7 MPa. The 10 mm adjustable window helps when you need to match end positions precisely on-site or share a spare across 390-400 mm stroke variants. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since this is a no-S SKU, it cannot accept a magnetic sensor. For any stroke over 500 mm, guide the load externally to prevent side-load wear on the rod and seals.
Quick checklist
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 force is 5006 kgf at 1.0 MPa. It uses a G1 air port and a 50 mm rod with an M42x2.0 thread.
The nominal 400 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on site by up to 10 mm, giving a usable extend range of 390-400 mm while the retract end remains fixed. This mechanism sets the end position and is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve to hold a load.
