Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-20 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 SGCJ125X200-20
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that shortens the extend stroke on-site by up to 20 mm. The nominal 200 mm stroke remains the maximum travel, allowing you to fine-tune the end position without physically swapping the actuator. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity, while the two-way piston seal ensures reliable bidirectional operation.
With a safe working load of roughly 3682 N, it can vertically lift about 313 kg with a 2:1 safety margin. This G1/2 ported unit features a 32 mm rod and 40 mm adjustable air cushions at both ends. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors. Note that the adjustable stop sets the end position but does not lock the load; a pilot-operated check valve or external rod lock is required for holding.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-20 Is Used
Press Fit Tuning
Micro-adjust the 20 mm extend window on-site to set the exact pressing depth for bearings without changing the actuator body.
Divertor Gate Stop
Fine-tune the extended gate position to accommodate varying package sizes on a packaging line while using the full retract stroke.
Pallet Lift Stop
Utilize the 6136 N push force to lift loads up to 313 kg vertically, tweaking the lift height precisely at the fixture.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-20 the Right Cylinder?
When sizing this 125 mm bore actuator against its neighbors, stepping down is not an option as it is the smallest in the SGCJ family, but stepping up to the 160 mm bore increases the 0.5 MPa push force to 10053 N. The 20 mm on-site adjustability window is highly beneficial for sharing a single spare cylinder across multiple stroke variants or finalizing end positions during machine commissioning. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For this 200 mm stroke, side loads are generally manageable, but for any stroke exceeding 500 mm, always guide the load to prevent rod bending. To add position sensing, you must select the -S magnet variant.
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 SGCJ125X200-20 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 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.
The external adjuster allows you to shorten the extend stroke by up to 20 mm on-site, meaning usable extend travel is 180 to 200 mm. The nominal 200 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
