Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGCJ125X100-100
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster to fine-tune the extend end position without swapping the unit. Four steel tie rods clamp the aluminum barrel to the covers, yielding a rigid framework that drops into existing ISO 15552 mounting-interface fixtures. It handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
The SGCJ125X100-100 carries a 100 mm nominal stroke that can be shortened on-site by up to 100 mm via the external stop screw, while the retract end remains fixed. Air enters through a G1/2 port to drive the Ø32 mm rod, and adjustable 40 mm air cushions decelerate the piston at both ends. Note that this specific SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors; adding the -S variant enables that switch set.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100 Is Used
Press Fit Dialing
Fine-tune the extend stroke on-site by up to 100 mm to set precise pressing depths for bearing insertion without machining custom spacers.
Divertor Positioning
Adjust the extend stop to alter the stroke length for sorting different package sizes on a shared conveyor line using one cylinder model.
Pallet Stop Tuning
Shorten the extend stroke on the fly to accommodate varying pallet widths at a packaging station while maintaining a fixed retract end.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100 the Right Cylinder?
When sizing this 125 mm bore against its neighbors, stepping down is not an option as it sits at the low edge of the SGCJ range, but stepping up to the 160 mm bore increases the 0.5 MPa push force to 10053 N. The 100 mm adjustable-stroke window is highly beneficial for sharing a single spare cylinder across multiple stroke variants or dialing in exact end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, position sensing is impossible without upgrading to the -S version. Even at 100 mm, guide the load to prevent side-load wear.
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 SGCJ125X100-100 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 max force is 1251 kgf at 1.0 MPa. The air port size is G1/2.
The 100 mm nominal stroke is the maximum extend length. The external adjuster allows you to shorten the usable extend stroke on-site by up to 100 mm, down to zero. The retract end is fixed, and this stop mechanism is for positioning only, not for holding a load.
