Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-75S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-75S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø160mm bore and 300mm stroke, G3/4 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 SGCJ160X300-75S
Delivering 10053 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 75 mm. The nominal 300 mm stroke remains the maximum travel, yielding a usable extend range of 225 to 300 mm, while the retract end stays fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the built-in piston magnet supports CMSG, DMSG, or EMSG switches for precise position detection. A G3/4 port supplies air, and adjustable air cushions of 50 mm decelerate the piston at both ends.
This double-acting single-rod actuator handles a safe working load of about 6032 N, which translates to lifting roughly 512 kg vertically with a 2:1 safety margin. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. The default TPU seals provide long service life across a -20 to +70 C range, though a Viton H option extends heat resistance up to 150 C. Note that the adjustable stop sets the end position but does not hold the load on air loss; pair it with an external rod lock or pilot-operated check valve for secure load holding.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-75S Is Used
Press Fit Tuning
Micro-adjust the 300 mm extend stroke by up to 75 mm on-site to set precise bearing press depths without changing tooling mounts.
Divertor Stroke Control
Shorten the extend position dynamically to handle varying package sizes on a sorting line while maintaining full retract travel.
Pallet Stop Calibration
Dial in the exact stop location for mixed pallet heights, using the external adjuster to set the 225 to 300 mm extend window.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-75S the Right Cylinder?
When sizing this 160 mm bore actuator, stepping down to a 125 mm bore yields 6136 N of push force at 0.5 MPa, whereas stepping up to a 200 mm bore provides 15708 N. The 75 mm adjustable window is ideal for fine-tuning the extend end position on-site without physically swapping the cylinder, allowing one spare to service multiple stroke variants. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The integrated -S magnet enables CMSG, DMSG, and EMSG sensor use. Because the 300 mm stroke falls below the 500 mm threshold, side-load guiding requirements are less critical than on longer strokes, but linear guidance is still recommended for heavy offset loads.
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 SGCJ160X300-75S FAQ
At 0.5 MPa this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa the push increases to 14074 N and the pull to 13194 N. The theoretical maximum force is 2050 kgf at 1.0 MPa. It features a 40 mm rod, a G3/4 air port, and 50 mm adjustable air cushions.
The external adjuster allows you to shorten the extend stroke by up to 75 mm directly on-site. With a nominal 300 mm maximum stroke, the usable extend range becomes 225 to 300 mm, while the retract end remains fixed. This mechanism sets the end position for fine-tuning but does not lock the load; a separate rod lock or pilot-operated check valve is required for load holding.
