Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 400mm 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 SGCJ125X400-10
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 aluminium barrel for high structural rigidity. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin. The G1/2 port feeds a 32 mm piston rod that operates at 30-500 mm/s.
The external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 390-400 mm without changing the cylinder itself. You can fine-tune the end position precisely, while the retract end remains fixed. A two-way piston seal pairs with adjustable air cushions at both ends, and the ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10 Is Used
Press Fit Trimming
Dial in the exact 390-400 mm extend stop on-site to trim components precisely without remounting the entire fixture.
Divertor Gate Adjustment
Fine-tune the actuator end position by up to 10 mm to accommodate different package sizes on a shared conveyor line.
Pallet Stopper Tuning
Adjust the extend stroke window to set exact pallet stopping distances without recalculating the fixed retract end.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10 the Right Cylinder?
When sizing this unit, the neighbouring 160 mm bore steps up to 10053 N at 0.5 MPa, while smaller standard bores sit below this class. The 10 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants or trimming end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this 400 mm stroke exceeds 500 mm is false, but for any stroke at or above 500 mm you must guide the load to prevent side-load wear. This specific SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG sensors; choose the -S variant if you need position detection.
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 SGCJ125X400-10 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it yields 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 nominal 400 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 10 mm on-site, yielding a usable extend range of 390-400 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
