The AirTAC Airtac SGC Standard Cylinder SGC125X380 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 380mm stroke, G1/2 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 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles substantial workloads across a 380 mm stroke. The four steel tie rods clamp the aluminium barrel to the covers, providing the high rigidity needed for heavy thrust, while a two-way piston seal maintains an internal oil reservoir for long service life. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without redesign.
For practical sizing, plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The Ø32 mm carbon steel rod has a 20 µm hard chrome plating, and the body features a G1/2 port. Note that this specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG, or EMSG position switches without upgrading to the magnet-equipped variant.

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.
Ejects heavy formed steel panels from press dies using a 380 mm stroke, relying on the 6136 N push force to overcome binder strap friction.
Separates empty wooden pallets from a magazine stack, utilizing the tie-rod rigidity to handle pallet weight without barrel deflection.
Actuates a routing gate on a packaging line to divert loaded crates, taking advantage of the ISO 15552 mounting interface for easy bracket alignment.
When sizing this 125 mm bore unit, verify if the 6136 N push at 0.5 MPa is sufficient, as stepping up to the 160 mm bore yields 10053 N. If your application requires less force, there is no smaller SGC bore available, so you would need to look outside the series. Because this 380 mm stroke is substantial, ensure external guide rails support any side loads to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end of stroke and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Furthermore, without the -S magnet option, this model cannot accept magnetic sensors for end-of-stroke detection.
Quick checklist
The SGC125X380 provides 6136 N push and 5734 N pull at 0.5 MPa, increasing to 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and features a 40 mm adjustable air cushion at both ends.
No, this specific SKU does not include the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic switches. If you require position feedback, you must select the SGC125X380-S variant or use external mechanical limit switches.
