Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X300-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X300-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 300mm 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 SGCJ125X300-10S
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 structural rigidity. The built-in piston magnet supports CMSG, DMSG, and EMSG position switches, while the G1/2 port handles the 30-500 mm/s speed range.
An external adjuster lets you shorten the extend stroke on-site by up to 10 mm, meaning the usable extend range is 290-300 mm without changing the cylinder itself. This on-site end-position tuning is paired with a two-way piston seal and adjustable air cushions at both ends. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X300-10S Is Used
Press Fit Tuning
Fine-tune the 290-300 mm extend end position on-site to set precise insertion depth for pressing bearings without swapping the cylinder.
Divertor Gate Stop
Adjust the 10 mm extend window to dial in the exact gate open position for varying package sizes on a heavy sorting conveyor.
Pallet Positioning
Shift pallets with 6136 N of force and tweak the extend stop to accommodate different pallet widths without repositioning the fixture.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X300-10S the Right Cylinder?
When sizing this unit, the 125 mm bore provides 6136 N push at 0.5 MPa, sitting at the low edge below the 160 mm bore that outputs 10053 N. The 10 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning the end position after installation. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the stroke is 300 mm, ensure you use a guide to prevent side-load damage. The -S suffix confirms the magnet is present for sensors.
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 SGCJ125X300-10S 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 max force is 1251 kgf at 1.0 MPa. The air port is G1/2.
The 300 mm nominal stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 290-300 mm. The retract end is fixed, and this stop is for position tuning only, not load holding.
