The AirTAC SGCJ200-250 Adjustable Cylinder SGCJ250X80-100 is a genuine double acting, double rod, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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.
Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity, while the ISO 15552 mounting interface ensures dimensional interchangeability for large-bore fixtures. The G1 air port and 50 mm piston rod handle heavy loads, and the 60 mm adjustable air cushions decelerate the piston at both ends.
Because the nominal 80 mm stroke represents the maximum extend length, the external stop screw lets you shorten the travel by up to 100 mm without changing the cylinder itself. Note that this SKU lacks a magnet and cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches. Also, TPU seals are not available on this 250 mm bore, though a Viton H option extends the operating temperature range from 0 to 150 C.

SGCJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

|---|---|
| 250 | Bore size in mm (125 / 160 / 200 / 250). |
| ×80 | Stroke length in mm. |

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. On Ø250 the blank code is the standard NBR build (no TPU).
Provides 1251 kg of vertical holding margin to secure heavy pallets during banding, with the 100 mm adjuster tuning the clamp reach for varying load sizes.
Ejects substantial industrial molds using a 50 mm rod and G1 port, with 60 mm adjustable cushions decelerating the heavy payload at stroke end.
The 100 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or dialing in exact end positions on-site. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-magnet SKU, it cannot accept position sensors; you must specify the -S option to use CMSG, DMSG, or EMSG switches. Even at an 80 mm stroke, always verify your guide bearings to prevent side-load wear.
Quick checklist
This 250 mm bore cylinder uses a G1 port, a 50 mm piston rod with an M42x2.0 thread, and 60 mm adjustable air cushions.
The nominal 80 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke by up to 100 mm on site to fine-tune the end position, while the retract end remains fixed. This stop only sets position; it does not hold the load on air loss, so you need an external rod lock or pilot-operated check valve for load holding.
