Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGCJ125X1000-50S
Delivering 6136 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 50 mm. The nominal 1000 mm travel remains the maximum, letting you fine-tune the end position without physically swapping the actuator. A built-in piston magnet comes standard, supporting CMSG, DMSG, and EMSG electronic or reed switches for precise position detection.
Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, while the ISO 15552 mounting interface guarantees dimensional interchangeability across standard fixtures. The G1/2 port feeds the 32 mm piston rod, and adjustable 40 mm air cushions decelerate the payload at both ends. Handling a safe working load of roughly 3682 N, it can lift about 313 kg vertically with a 2:1 safety margin. The standard TPU seals operate from -20 to +70 C, though a Viton H option extends this to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50S Is Used
Press Stroke Calibration
Fine-tune the extend endpoint by up to 50 mm on-site to perfectly set material contact depth without machining new hard stops.
Pallet Positioning
Adjust the extend travel to accommodate varying pallet lengths while maintaining the full 1000 mm maximum reach for large fixtures.
Divertor Gate Timing
Dial in the exact gate extension required to route different package sizes on a high-speed line using the external stop screw.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50S the Right Cylinder?
When sizing this actuator, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, whereas a 125 mm bore provides the 6136 N listed here. The 50 mm adjustable window is particularly useful when you need to share a single spare across multiple stroke variants or dial in the exact end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this unit features a 1000 mm stroke, you must provide external guide rails to prevent rod bending and absorb side loads. The included -S magnet allows seamless sensor integration, but remember that a plain pneumatic cylinder drifts without live air; use an external rod lock or pilot-operated check valve for load holding.
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 SGCJ125X1000-50S FAQ
This 125 mm bore cylinder uses a G1/2 air port and a 32 mm rod. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, yielding a usable extend range of 950 to 1000 mm. The nominal 1000 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
