The AirTAC Airtac SGC Standard Cylinder SGC125X1800N is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1800mm 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 over a 1800 mm stroke. Because 1800 mm exceeds the 1500 mm standard maximum, this is a made-to-order unit. It features a G1/2 port and an M27x2.0 rod thread, utilizing a robust tie-rod design where four steel rods clamp the aluminum barrel to the covers for high structural rigidity.
This specific SKU uses NBR seals (the N suffix) rather than the standard TPU, making it suitable for specific fluid or temperature demands within its -20 to +70 C operating range. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin. The two-way piston seal retains an oil reservoir for long life, and it is dimensionally interchangeable per the ISO 15552 mounting interface.

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.
Moves heavy pallets or structural assemblies down a 1.8-meter line, utilizing the 6136 N push force to overcome friction over long distances.
Ejects packaged goods from elevated staging platforms, where the 1800 mm stroke clears tall machinery envelopes safely.
Compresses industrial waste in large baling chambers, relying on the NBR seals and tie-rod rigidity for consistent long-stroke compression.
When sizing this 125 mm bore, stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa, while the 125 mm is the smallest available SGC option. Because this 1800 mm length is a non-standard made-to-order stroke, you must account for rod-bending and side-load risks; always use external guides to support the rod end over this extended travel. Without external guides, deflection can damage the piston and seals.
This model lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. Furthermore, a standard double-acting cylinder drifts when air is lost or a valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the stroke ends and do not act as a brake. To hold a load securely, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 125 mm bore cylinder 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 operates at 30-500 mm/s, accepts pressures from 0.15-1.0 MPa, and uses a G1/2 port.
No, this specific SKU lacks the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the -S variant for sensing. It is built with a genuine ISO 15552 tie-rod interface, allowing it to drop into existing large-bore ISO 15552 fixtures.
