Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-75
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-75 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCJ125X200-75
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 G1/2 port feeds a double-acting single-rod mechanism with a 32 mm piston and M27x2.0 rod thread, while a two-way piston seal extends service life.
An external adjuster lets you shorten the extend stroke on-site by up to 75 mm, dropping the usable forward travel from the 200 mm maximum down to 125 mm without swapping the cylinder. This yields a safe working load of roughly 3682 N, easily lifting about 313 kg vertically with a 2:1 margin. Standard TPU seals handle -20 to +70 C, though a Viton H option raises the thermal limit to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-75 Is Used
Press Fit Tuning
Dial in the exact bottoming position of a 125 mm bore press by trimming the extend stroke up to 75 mm on-site, ensuring perfect bearing seating without remounting hardware.
Divertor Stroke Trim
Adjust the pusher extension on a sorting line to match varying package widths, shortening the 200 mm forward travel to prevent over-travel on smaller parcels.
Pallet Stop Calibration
Set the precise stop distance for inbound pallets by turning the external adjuster, locking the end position exactly where the load needs to halt for wrapping.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-75 the Right Cylinder?
When sizing this 125 mm bore against its neighbors, the smaller end of the family lacks the sheer thrust needed for heavy pressing, whereas stepping up to the 160 mm bore jumps the 0.5 MPa push force to 10053 N. The 75 mm adjust window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic sensors. For any stroke over 500 mm, always guide the load 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 SGCJ125X200-75 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa the output rises to 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The 200 mm nominal stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable range of 125 to 200 mm. The retract end remains fixed, and this stop is for positioning only, not load holding.
