Airtac SGC Standard Cylinder SGC125X160SCB
The AirTAC Airtac SGC Standard Cylinder SGC125X160SCB is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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.

About the Airtac SGC Standard Cylinder SGC125X160SCB
Delivering 6136 N of push force at 0.5 MPa, this double-acting tie-rod cylinder handles heavy automation tasks with ease. The Ø125 mm bore uses a G1/2 air port and an M27x2.0 piston rod. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed for large-bore thrust, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 3682 N of real work at 0.5 MPa, which safely lifts roughly 313 kg vertically with a 2:1 margin.
Because this SKU includes the -S magnet, it is ready for CMSG, DMSG, or EMSG position switches. The standard TPU seals operate from -20 to +70 C, with Viton H available for 0-150 C environments. The CB clevis mount integrated into this model utilizes the standardized ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures.

Where the Airtac SGC Standard Cylinder SGC125X160SCB Is Used
Press Ejection
Provides the robust 6136 N push stroke needed to eject formed metal parts from heavy stamping presses.
Pallet Lift Gate
Raises and lowers loaded pallet gates using the CB clevis mount to accommodate pivoting articulation.
Heavy Package Divert
Actuates heavy-duty divert arms on packaging conveyors, moving dense goods at 30-500 mm/s.
Is the Airtac SGC Standard Cylinder SGC125X160SCB the Right Cylinder?
When sizing this actuator, compare its 6136 N push force at 0.5 MPa against the next size up: the Ø160 bore provides 10053 N if your application demands more power. As the 125 mm bore is the smallest in the SGC family, there is no smaller standard option. The 160 mm stroke offers good travel, but always verify side-load limits and use external guide rails to prevent rod bending over extended distances.
The CB clevis mount is ideal for pivoting mechanisms, but note that a plain cylinder drifts when air is lost or the valve is centered. The adjustable air cushion only decelerates the piston near the end of stroke; it does not function as a lock. Use an external rod lock or pilot-operated check valve if the load must be held in place.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGC Standard Cylinder SGC125X160SCB FAQ
