Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGCJ125X350-40S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy automation tasks with ease. Four steel tie rods clamp the aluminum barrel to the covers, while the standard G1/2 port matches the 125 mm bore specification. It carries a built-in piston magnet for position sensing.
The external adjuster allows you to shorten the extend stroke on-site by up to 40 mm, giving a usable range of 310 to 350 mm without changing the cylinder itself. This on-site tuning is ideal for sharing spares across stroke variants. The standard TPU seals provide long life, though a Viton H option extends operation to 150 C. With a 6136 N extend force, it safely handles about 3682 N of real work, which means lifting roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-40S Is Used
Press Fit Tuning
Dial in the exact 310 to 350 mm extend position on-site to seat bearings without changing hard stops.
Divert Arm Adjustment
Shift the extend endpoint by up to 40 mm to accommodate different package sizes on a shared line.
Pallet Stop Calibration
Fine-tune the stopping distance for varying pallet dimensions while maintaining a fixed retract end.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-40S the Right Cylinder?
When sizing this unit, the neighboring 160 mm bore steps up to 10053 N at 0.5 MPa, whereas dropping below 125 mm falls off the large-bore ISO 15552 map. The 40 mm adjustable window helps fine-tune end positions on-site and lets you standardize one spare across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix confirms the magnet is present for CMSG, DMSG, or EMSG switches. Because the 350 mm stroke generates leverage, always mount a guide to absorb side loads and prevent rod bending.
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 SGCJ125X350-40S 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 max is 1251 kgf at 1.0 MPa. The 125 mm bore uses a G1/2 port.
An external stop screw shortens the extend stroke by up to 40 mm on-site, giving a usable range of 310 to 350 mm. The nominal 350 mm is the maximum, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
