Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCJ125X200-40S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 40 mm external adjuster to shorten the extend stroke on-site. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port matches the 125 mm bore standard. Because the nominal 200 mm stroke acts as the maximum, you can fine-tune the end position down to 160 mm without swapping the cylinder.
The built-in piston magnet supports CMSG, DMSG, and EMSG sensors for precise position detection. This model handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin. A two-way piston seal ensures reliable operation across the 30-500 mm/s speed range, while the adjustable air cushions absorb impact at both ends.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40S Is Used
Press Fit Tuning
Dial in the exact insertion depth of bearings on an assembly line by turning the external adjuster rather than repositioning the entire fixture.
Variable Stroke Divert
Adjust the extend stroke on a sorting diverter arm to handle different package widths without changing out the pneumatic cylinder.
Pallet Stop Calibration
Fine-tune the stopping position of pallets on a heavy-duty roller conveyor by shortening the extend stroke up to 40 mm on-site.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40S the Right Cylinder?
When sizing this 125 mm bore unit, stepping down is not an option as it sits at the low edge of the SGCJ family, but stepping up to the 160 mm bore yields 10053 N of push force at 0.5 MPa if your application demands more power. The adjustable stroke feature is ideal for sharing a single spare cylinder across multiple stroke variants or dialing in end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches. Because the 200 mm stroke is relatively short, side-load stress is minimal, but always guide the rod end 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 SGCJ125X200-40S FAQ
This 125 mm bore cylinder uses a G1/2 port and a 32 mm rod. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
The nominal 200 mm stroke is the maximum extend length. An external stop screw lets you shorten the usable extend stroke by up to 40 mm on-site, yielding a 160 to 200 mm range. The retract end remains fixed, and this mechanism only sets the end position rather than holding the load.
