Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10S 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 SGCJ125X150-10S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a piston magnet for position sensing. The four steel tie rods clamp the aluminum barrel securely to the covers, while the G1/2 port supplies ample air volume for its 30-500 mm/s speed range. It provides a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
The -10 code defines an external adjuster that shortens the extend stroke on site by up to 10 mm, letting you fine-tune the end position from 140 to 150 mm without changing the cylinder itself. The retract end remains fixed. Standard TPU seals handle -20 to +70 C, though a Viton H option extends this to 0-150 C. Because the -S suffix is present, you can mount CMSG, DMSG, or EMSG sensors directly for precise detection.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10S Is Used
Press Fit Tuning
Micro-adjust the 10 mm extend window on-site to set the exact bottoming force for pressing bearings without swapping physical spacers.
Divertor Gate Stop
Fine-tune the actuator end position to accommodate different package sizes on a sorting line while using the magnet for end confirmation.
Pallet Lift Stop
Lift loads safely using the 313 kg vertical capacity and adjust the extend stroke to match varying pallet heights precisely.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10S the Right Cylinder?
When sizing this 125 mm bore unit, stepping down is not an option as it is the smallest in the SGCJ family, but stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N. The adjustable stroke feature is highly useful for sharing a single spare cylinder across multiple fixtures that require slightly different extend end positions. You can mount it using FA, LB, TC, FTC, TCM1, or TCM2 hardware. Since the stroke is under 500 mm, side-load risks are minimal, but always guide the load to prevent rod binding. The built-in magnet supports CMSG/DMSG/EMSG switches, whereas a non-S SKU cannot take a sensor.
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 SGCJ125X150-10S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port and features a 32 mm rod with an M27x2.0 thread.
The nominal stroke is 150 mm, which is the maximum extend length. The external -10 mm adjuster allows you to shorten the extend stroke on-site down to 140 mm to fine-tune the end position. The retract end is fixed. Note that this mechanism only sets the end position; a plain cylinder does not hold load on air loss, so use an external rod lock or pilot-operated check valve for load holding.
