Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-40S 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 SGCJ160X300-40S
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 40 mm. Four steel tie rods clamp the aluminum barrel to the covers, and the built-in piston magnet supports CMSG, DMSG, and EMSG sensors for precise position detection. The G3/4 port feeds a 40 mm rod with a 50 mm adjustable air cushion at each end.
Because the nominal 300 mm stroke represents the maximum extend length, you can fine-tune the end position down to 260 mm without swapping the cylinder. This yields a safe working load of roughly 6032 N, which translates to lifting about 512 kg vertically with a 2:1 safety margin. The default TPU seals handle -20 to +70 C, while the Viton H option extends operation up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-40S Is Used
Press Tonnage Calibration
Use the 40 mm extend-shortening window to precisely set the bottoming height of a 10053 N pressing operation without machining new spacers.
Divertor Arm Positioning
Dial in the exact 260 to 300 mm reach of a heavy divertor arm on-site to accommodate different package widths on the fly.
Pallet Stop Alignment
Fine-tune the stopping endpoint of a 160 mm bore pallet stop to match conveyor height variances using the external adjuster.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X300-40S the Right Cylinder?
When sizing this unit, the 125 mm bore provides 6136 N push at 0.5 MPa for lighter loads, whereas the 200 mm bore steps up to 15708 N for heavier demands. The 40 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix confirms the magnet is present for electronic switches. At 300 mm stroke, guide the load to prevent side-load binding.
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 SGCJ160X300-40S FAQ
At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa it pushes 14074 N and pulls 13194 N. The theoretical maximum force is 2050 kgf at 1.0 MPa. This bore features a G3/4 air port, a 40 mm rod, and a 50 mm adjustable cushion.
The nominal 300 mm stroke is the maximum extend length. The external stop screw lets you shorten the extend stroke by up to 40 mm on-site, yielding a usable range of 260 to 300 mm. The retract end remains fixed, and this stop only sets the end position; it does not lock the load.
