Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40 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 SGCJ125X200-40
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that lets you shorten the extend stroke on-site by up to 40 mm. The nominal 200 mm stroke remains the maximum travel, yielding a usable 160 to 200 mm extend window, while the retract end stays fixed. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the unit is dimensionally interchangeable per the ISO 15552 mounting interface. It uses a G1/2 port and an M27x2.0 rod thread.
This double-acting single-rod actuator handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 safety margin. The two-way piston seal ensures reliable operation across the 30 to 500 mm/s speed range. Standard TPU seals support a -20 to +70 C operating range, though a Viton H option extends this to 150 C. Note that this specific SKU lacks a magnet and cannot accept position sensors; adding the -S variant enables CMSG, DMSG, or EMSG switches.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40 Is Used
Press Fit Tuning
Micro-adjust the 40 mm extend window on-site to set exact pressing depths for bearing insertion without swapping actuators.
Divertor Stroke Trim
Fine-tune the extend end position of a sorting arm to accommodate different package sizes on the fly.
Pallet Stop Calibration
Dial in the exact stop position for varying pallet widths directly at the machine, using the full 6136 N thrust to halt loads.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-40 the Right Cylinder?
When sizing this 125 mm bore actuator, the neighboring 160 mm bore provides significantly greater thrust (10053 N push at 0.5 MPa) for heavier loads, while smaller bores suit lighter duties. The adjustable stroke feature is particularly valuable when you need to fine-tune the extend end position on-site without physically changing the cylinder, or when you want a single spare part to cover slight stroke variations across similar machines. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, it cannot host CMSG, DMSG, or EMSG sensors. For any application approaching or exceeding 500 mm of stroke, always use external guide rails to prevent side-load damage to the rod and seals.
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 SGCJ125X200-40 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port.
An external stop screw lets you shorten the extend stroke on-site by up to 40 mm. The usable extend range is 160 to 200 mm, with the 200 mm nominal stroke being the maximum travel. The retract end remains fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
