Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGCJ125X350-10
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 10 mm external adjuster to fine-tune the extend end position on-site. Four steel tie rods clamp the aluminium barrel to the covers, and the standard TPU seals provide excellent wear resistance. The G1/2 port feeds the 32 mm piston rod, yielding a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
The nominal 350 mm stroke represents the maximum travel, as the external stop screw shortens the extend stroke by up to 10 mm without changing the cylinder body. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. Note that this specific SKU lacks a magnet and cannot accept CMSG or DMSG sensors; adding the -S variant enables that capability. Furthermore, the adjustable air cushions only decelerate the piston near the ends and do not hold the load on air loss.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10 Is Used
Press Fit Tuning
Dial in the exact bottoming position of a 350 mm press stroke within a 10 mm window to accommodate varying insert depths without swapping cylinders.
Transfer Stopper
Act as a heavy-duty stop gate where the extend end position requires minor on-site tweaks to align with different product widths on the line.
Pallet Positioning
Push pallets into a wrapping station, using the external adjuster to compensate for slight mechanical drift over time while delivering 6136 N of force.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10 the Right Cylinder?
When sizing this unit, the neighbouring 160 mm bore steps up significantly to 10053 N at 0.5 MPa, whereas the 125 mm bore sits at the low edge of the large-bore range. The 10 mm adjustable window is highly useful for sharing a single spare cylinder across machines that need slightly different extend end positions. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the 350 mm stroke exceeds 500 mm, you should guide the rod end to prevent excessive side loading. Finally, this non-magnetic SKU cannot host a sensor switch; you require the -S version for position feedback.
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 SGCJ125X350-10 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. It uses a G1/2 port and a 32 mm rod.
The nominal 350 mm stroke is the maximum travel. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 340 to 350 mm. The retract end remains fixed, and this mechanism sets the end position rather than locking the load.
