Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X30-30S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X30-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 30mm 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 SGCJ125~160 Adjustable Cylinder SGCJ125X30-30S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates four steel rods clamping an aluminum barrel for high structural rigidity. It is a double-acting single-rod actuator with a 125 mm bore, a G1/2 port, and a built-in piston magnet for position sensing. The external stop screw provides a 30 mm on-site extend-shortening window, letting you fine-tune the end position without swapping the actuator.
The retract end remains fixed while the usable extend stroke shrinks from the 30 mm maximum down to zero as needed. This yields a safe working load of about 3682 N, which equates to lifting roughly 313 kg vertically with a 2:1 margin. The standard TPU seals handle -20 to +70 C, while the -S suffix means it is ready for CMSG, DMSG, or EMSG switches. Remember that the adjustable air cushions only decelerate the piston; they do not hold the load on air loss.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X30-30S Is Used
Short-Stroke Clamping
Apply 6136 N of clamping force on heavy weldments, using the 30 mm adjuster to dial in the exact material thickness on the production floor.
Transfer Stopper Gate
Halt large pallets on a conveyor, relying on the G1/2 port for rapid actuation and the external stop screw to tune the gate drop height.
Press Fit Positioning
Drive small bearings into housings with a precise 0 to 30 mm stroke, adjusting the extend endpoint without reprogramming the machine cycle.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X30-30S the Right Cylinder?
When sizing this actuator, stepping down is not an option as 125 mm is the smallest SGCJ bore, offering 6136 N push at 0.5 MPa. If you need substantially more force, the 160 mm bore provides 10053 N. The 30 mm adjustable window is ideal for sharing a spare cylinder across multiple short-stroke fixtures, as you can tune the exact extend endpoint on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this unit carries the -S suffix, it accepts CMSG, DMSG, or EMSG sensors. Even at this short 30 mm stroke, ensure your guide mechanism handles any side loads to prevent binding.
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 SGCJ125~160 Adjustable Cylinder SGCJ125X30-30S FAQ
This 125 mm bore cylinder features a G1/2 air port and a 32 mm rod. It generates 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.
The 30 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, dropping the usable extend length to zero if needed. The retract end is fixed, and this stop is an end-position adjuster, not a load-holding lock.
