Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-50
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGCJ125X160-50
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 50 mm. The nominal 160 mm stroke serves as the maximum, yielding a usable extend range of 110 to 160 mm, while the retract end remains fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the design is dimensionally interchangeable per the ISO 15552 mounting interface. It features a G1/2 port, an M27x2.0 rod thread, and 40 mm adjustable air cushions at both ends.
This 125 mm bore actuator handles about 3682 N of safe working load, which translates to roughly 313 kg lifted vertically with a 2:1 margin. A two-way piston seal ensures reliable operation across the 30-500 mm/s speed range, and the standard TPU seals accommodate temperatures from -20 to +70 C. Because this specific SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG sensors. Note that the adjustable stop sets the end position but does not function as a load lock; the air cushions only decelerate the piston near the stroke ends.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-50 Is Used
Press Fit Tuning
Micro-adjust the 110-160 mm extend stroke on-site to set precise insertion depths for bearing press operations without swapping cylinders.
Diverters
Provides 6136 N of push force to actuate heavy-duty conveyor sorting gates, with the external stop allowing quick timing calibration.
Pallet Stops
Halts loaded pallets using the 40 mm adjustable air cushions, while the 50 mm stroke window fine-tunes the stopping distance for different load sizes.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-50 the Right Cylinder?
When sizing this actuator, stepping down to a smaller bore reduces the footprint but sacrifices the 6136 N push force available at 0.5 MPa, whereas moving up to a 160 mm bore increases thrust to 10053 N. The 50 mm adjustable window is particularly useful for sharing a single spare cylinder across multiple stroke variants or fine-tuning the end position without mechanically remounting the body. SGCJ mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For any stroke length at or exceeding 500 mm, always use external guide rails to prevent excessive side loading on the rod. To add position sensing, select the -S variant instead, as this non-magnetic SKU cannot support switches.
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 SGCJ125X160-50 FAQ
At 0.5 MPa this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa the push increases to 8590 N and the pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and features a 40 mm adjustable air cushion at both ends.
The -50 code indicates an external adjuster that allows you to shorten the extend stroke by up to 50 mm on-site. The nominal 160 mm stroke is the maximum, giving a usable extend range of 110 to 160 mm, while the retract end remains fixed. This mechanism only sets the end position and does not hold the load; for load holding on air loss, you must use an external rod lock or pilot-operated check valve.
