About the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X400-50S
Delivering 10053 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy automation tasks with ease. Four steel tie rods clamp the aluminum barrel to the covers for maximum structural rigidity, while the G3/4 port feeds the 40 mm piston rod. A built-in piston magnet comes standard, supporting CMSG, DMSG, and EMSG sensor switches for precise position detection.
The external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, meaning the usable extension range is 350-400 mm without changing the cylinder mount. This on-site tuning is ideal for dialing in end positions, and it translates to a safe working load of roughly 6032 N or a vertical lift capacity of about 512 kg with a 2:1 margin. Standard TPU seals provide long life across -20 to +70 C, with a Viton H option available for 0-150 C environments.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X400-50S Is Used
Press Fit Tuning
Dial in the exact bottoming position of a 400 mm press stroke on-site using the 50 mm adjuster window, avoiding mechanical shim changes during tooling setup.
Pallet Stop Adjustment
Accommodate varying pallet lengths on a heavy-duty conveyor by tweaking the extend stop within the 350-400 mm range without swapping the actuator.
Heavy Lift Gate Actuation
Lift materials weighing up to 512 kg vertically with a 2:1 safety margin, relying on the 160 mm bore to provide consistent 10053 N thrust at 0.5 MPa.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X400-50S the Right Cylinder?
When sizing this 160 mm bore actuator, stepping down to a 125 mm bore yields 8590 N of push force at 0.7 MPa, whereas stepping up to a 200 mm bore provides 21991 N at the same pressure. The SGCJ series supports basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting attachments. Because this model includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG electronic and reed switches. The adjustable stroke feature is highly beneficial when you need to share a spare cylinder across multiple stroke variants or fine-tune the end position after mechanical installation. For any stroke length at or above 500 mm, always use a guide rail to prevent side-load damage to the piston rod.
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 SGCJ160X400-50S FAQ
At 0.5 MPa it provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa the push increases to 14074 N and the pull to 13194 N. The theoretical maximum force is 2050 kgf at 1.0 MPa.
The nominal 400 mm stroke is the maximum extension. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 350-400 mm while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
