Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGCJ125X125-10S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a built-in magnet for position sensing. Four steel tie rods clamp the aluminum barrel to the covers, ensuring structural rigidity while maintaining dimensional interchangeability per the ISO 15552 mounting interface for standard large-bore fixtures. The G1/2 port supplies air to the 32 mm rod, driving the double-acting piston at 30-500 mm/s.
The -10 code defines an external adjuster that shortens the extend stroke on-site by up to 10 mm, letting you fine-tune the 125 mm maximum travel without changing the cylinder itself. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin. Standard TPU seals operate from -20 to +70 C, while a Viton H option extends this to 150 C. The adjustable air cushions decelerate the load near stroke end, but the piston drifts on air loss, so fit an external rod lock for held loads.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10S Is Used
Press Fit Tuning
Dial in the exact bottoming position of a 125 mm press stroke within a 10 mm window to accommodate different bearing thicknesses without swapping cylinders.
Transfer Diverter
Adjust the extend endpoint on-site to deflect varying package sizes onto parallel conveyor lines using the integrated CMSG sensor feedback.
Pallet Stop Gate
Fine-tune the stopping depth of a pallet accumulator gate by up to 10 mm to handle mixed pallet footprints while absorbing 6136 N of impact thrust.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10S the Right Cylinder?
When sizing this 125 mm bore against its neighbors, the smaller 100 mm class lacks the thrust capacity, while the larger 160 mm bore jumps to 10053 N at 0.5 MPa, making this model the ideal middle ground for moderate heavy-duty work. The 10 mm adjustable extend window is highly useful when you need to share a single spare cylinder across multiple stroke variants or dial in a precise end position on the machine. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix confirms the piston magnet is present for CMSG, DMSG, or EMSG switches. Because the 125 mm stroke exceeds 500 mm, always use a guide rail to prevent side-load damage.
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 SGCJ125X125-10S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull force. At 0.7 MPa the push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and features a 32 mm piston rod with an M27x2.0 thread.
The -10 indicates an external adjuster that lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 115 to 125 mm. The nominal 125 mm stroke remains the maximum travel, and the retract end is fixed. This mechanism only sets the end position and does not lock the load.
