Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50S 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 SGCJ125X150-50S
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 150 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the built-in piston magnet supports CMSG, DMSG, or EMSG sensors for precise position detection.
Equipped with a G1/2 port and a 32 mm rod, the unit handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin. It carries adjustable air cushions of 40 mm at both ends to absorb impact. Standard TPU seals operate from -20 to +70 C, while a Viton H option extends this range up to 150 C for heated environments.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50S Is Used
Press Fit Tuning
Dial in the exact bottoming position of a 150 mm press stroke within a 50 mm window to accommodate varying insert heights without changing the cylinder.
Divertor Adjustment
Fine-tune the extend reach of a sorting gate on-site by up to 50 mm to handle different package widths on the fly.
Pallet Stopper
Adjust the stopping depth for mixed pallet sizes, using the 6136 N push force to halt heavy loads reliably.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50S the Right Cylinder?
When sizing this 125 mm bore actuator, the neighboring 160 mm bore provides 10053 N of push at 0.5 MPa if your application demands more power, whereas dropping down to smaller bores reduces the footprint and air consumption. The 50 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants or dialing in exact end positions during machine commissioning. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet allows for direct sensor mounting. For any stroke length at or above 500 mm, always use external guide rails to prevent side-load damage to the rod seals.
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 SGCJ125X150-50S 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. The air port size is G1/2.
The external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, meaning the usable extend travel is 100 to 150 mm. The nominal 150 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
