Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30 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 SGCJ125X160-30
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminum barrel for high rigidity. The G1/2 port feeds a 32 mm rod, and the two-way piston seal ensures reliable double-acting single-rod operation.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable 130-160 mm range while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder. It handles a safe working load of about 3682 N, which means lifting roughly 313 kg vertically with a 2:1 margin. Standard TPU seals work from -20 to +70 C, though a Viton H option extends this to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30 Is Used
Press Fit Tuning
Use the 30 mm extend-shortening window to precisely set the bottoming position for pressing bearings without machining new hard stops.
Divertor Stroke Trim
Adjust the extend end position on-site to perfectly align a divertor arm with varying package widths on the fly.
Pallet Stop Calibration
Fine-tune the stopping point of a pallet conveyor stopper within the 130-160 mm usable stroke to accommodate different pallet tolerances.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30 the Right Cylinder?
This 125 mm bore sits at the lower edge of the SGCJ range, offering 6136 N push at 0.5 MPa. If you need less force, step down to a smaller standard cylinder; if your application requires more power, move up to the 160 mm bore which provides 10053 N at 0.5 MPa. The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this specific SKU lacks the -S suffix, it cannot take a magnetic sensor; you need the -S version for CMSG, DMSG, or EMSG switches. For any stroke over 500 mm, always use a guide to prevent side-load damage.
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 SGCJ125X160-30 FAQ
This cylinder uses a G1/2 port. 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 force of 1251 kgf at 1.0 MPa.
The 160 mm nominal stroke is the maximum. An external adjuster lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable extend range of 130-160 mm. The retract end is fixed, and this stop only sets position; it does not hold the load without live air.
