The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-75 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.
Delivering massive thrust with a 250 mm bore, this double-acting single-rod tie-rod cylinder pushes 24543 N and pulls 23562 N at 0.5 MPa. The G1 air port feeds the 50 mm piston rod, generating a safe working load around 14726 N, which is roughly 1251 kg lifted vertically with a 2:1 margin. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity.
As a genuine ISO 15552 adjustable-stroke unit, it drops into existing large-bore ISO 15552 mounting interfaces. The external adjuster lets you shorten the extend stroke on site by up to 75 mm, giving a usable forward range of 425-500 mm without changing the cylinder. Note that TPU seals are not offered on this 250 mm bore; it uses NBR packings, with a Viton H option for 0-150 C heat.

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.
Elevates massive pallets in automated warehouses, using the 75 mm adjuster to dial in exact upper stops without repositioning the frame.
Pushes heavy billets into a forming press, relying on the 60 mm adjustable air cushions to decelerate the 50 mm rod smoothly at the end of travel.
Secures oversized injection molds, shortening the extend stroke on site by up to 75 mm to accommodate varying mold thicknesses precisely.
When sizing this 250 mm bore against neighbors, the 200 mm option provides 15708 N push at 0.5 MPa, while this 250 mm unit hits 24543 N at the same pressure. The 75 mm adjuster window is ideal for fine-tuning end positions on site or sharing a spare across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this is a no-S SKU, it cannot accept CMSG/DMSG/EMSG sensors. For the 500 mm stroke, use external guides to prevent rod bending and manage side loads.
Quick checklist
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. 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 maximum force is 5006 kgf at 1.0 MPa.
The nominal 500 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 75 mm, yielding a usable forward range of 425-500 mm. The retract end is fixed. This stop sets the end position and is not a load lock; use an external rod lock or pilot-operated check valve to hold a load.
