Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGCJ125X150-100S
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. The built-in magnet supports CMSG, DMSG and EMSG sensors for exact position detection, while the G1/2 port matches the 125 mm bore specification.
The -100 code defines an external adjuster that shortens the extend stroke on-site by up to 100 mm, letting you fine-tune the end position without changing the cylinder itself. The nominal 150 mm stroke remains the maximum, yielding a usable extend range of 50 to 150 mm. This configuration handles a safe working load of roughly 3682 N, which means you can vertically lift about 313 kg with a 2:1 safety margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100S Is Used
Press Stroke Tuning
Dial in the exact 50 to 150 mm extend position on a light-duty assembly press without swapping hardware, leveraging 6136 N of thrust at 0.5 MPa.
Variable Divert Gate
Adjust the extend stop on-site to change the gate angle for different package sizes, using the CMSG sensor signal to confirm the diverted position.
Vertical Lift Stop
Lift a 313 kg payload with a 2:1 safety margin and fine-tune the extend reach to clear obstructions, ensuring precise placement every cycle.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100S the Right Cylinder?
When sizing this unit, the neighbouring 160 mm bore steps up to 10053 N of push at 0.5 MPa, whereas smaller bores offer less force. The adjustable stroke is highly useful for sharing a single spare across multiple stroke variants or tuning end positions on-site. You can mount it via FA, LB, TC, FTC, TCM1 or TCM2 brackets. The -S suffix confirms the piston magnet is present for switches. Because the stroke is under 500 mm, side-load guide requirements are minimal, but always guide the rod to prevent binding. Note that a plain cylinder drifts on air loss; the cushion only decelerates, so add an external rod lock or pilot-operated check valve to hold a load securely.
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.
