Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGCJ125X160-75
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster to shorten the extend stroke on-site. The nominal 160 mm stroke represents the maximum travel, while the -75 code provides a 75 mm reduction window, yielding a usable extend range of 85 to 160 mm. This allows you to fine-tune the end position without physically swapping the cylinder. It handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
Four steel tie rods clamp the aluminum barrel to the covers, ensuring structural rigidity, and the unit is dimensionally interchangeable per the ISO 15552 mounting interface. The bore dictates a G1/2 port, a 32 mm rod, and 40 mm adjustable air cushions at both ends. This base SKU lacks a magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors without upgrading to the -S variant. Standard TPU seals operate from -20 to +70 C, though a Viton H option extends heat resistance up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75 Is Used
Press Fit Tuning
Micro-adjust the 85 to 160 mm extend stroke on-site to set precise insertion depths for bearing press fits without changing the actuator.
Divertor End Stop
Fine-tune the diverting arm end position by up to 75 mm to accommodate different package sizes on a shared production line.
Pallet Positioning
Dial in the exact push-off distance for varying pallet widths, utilizing the 6136 N thrust to shift heavy loads accurately.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75 the Right Cylinder?
When sizing this 125 mm bore unit, consider the neighboring options: step down to reduce footprint, or step up to 160 mm for 10053 N of push at 0.5 MPa. The adjustable stroke proves invaluable when you need on-site end-position tuning or want a shared spare across multiple stroke variants. Mounting choices include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-magnetized model, position sensing is impossible; select the -S version if you require electronic feedback. For strokes of 500 mm or longer, always incorporate external guide rails 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 SGCJ125X160-75 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it delivers 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.
The -75 code indicates an external adjuster that lets you shorten the extend stroke by up to 75 mm on-site. The nominal 160 mm stroke is the maximum, so the usable extend range is 85 to 160 mm. The retract end remains fixed. Note that this mechanism only sets end position; a plain cylinder does not hold load without live air, so use an external rod lock or pilot-operated check valve for holding.
