About the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10
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 without swapping parts. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port matches the 125 mm bore standard. The nominal 125 mm stroke represents the maximum travel, yielding a usable extend range of 115 to 125 mm while the retract end remains fixed. A two-way piston seal ensures reliable containment across the 30 to 500 mm/s speed range.
Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. Based on the 0.5 MPa thrust, it handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin. The standard TPU seals operate from -20 to +70 C, though a Viton H option extends this to 150 C. Note this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10 Is Used
Press Fit Tuning
Dial in the exact bottoming position of a press fit operation on-site using the 10 mm extend adjuster, avoiding mechanical shim changes when material thickness varies slightly.
Transfer Stopper Alignment
Fine-tune the stopping point of a heavy pallet on a conveyor by adjusting the extend stroke between 115 and 125 mm to accommodate different package dimensions without repositioning the cylinder.
Pallet Lift Height Trim
Adjust the extend end position on a lifting station to match varying pallet heights, utilizing the 6136 N thrust to elevate loads safely while trimming the final 10 mm of travel.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-10 the Right Cylinder?
When sizing this unit, the 125 mm bore sits at the low edge of the SGCJ family, producing 6136 N push and 5734 N pull at 0.5 MPa. Stepping up to the 160 mm bore yields 10053 N of push force, whereas this 125 mm option is ideal when 8590 N at 0.7 MPa is sufficient. The 10 mm adjustable window is particularly useful for synchronizing multiple cylinders or dialing in a shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this non-magnetized version cannot host position sensors, adding the -S variant is required for CMSG, DMSG, or EMSG switches. For this 125 mm stroke, side loads are minimal, but any application exceeding 500 mm of travel should incorporate an external guide to prevent rod binding.
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 SGCJ125X125-10 FAQ
This 125 mm bore cylinder features a G1/2 air port and a 32 mm piston 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. It includes 40 mm adjustable air cushions at both ends.
The -10 code indicates a 10 mm external adjustment window. The nominal 125 mm stroke is the maximum travel, and you can shorten the extend stroke on-site by up to 10 mm, yielding a usable extend range of 115 to 125 mm. The retract end is fixed, and this adjuster sets the end position rather than acting as a load lock.
