Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCJ125X200-100S
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder brings large-bore power to applications needing exact end-position tuning. The four steel tie rods clamp the aluminum barrel securely to the covers, while the G1/2 port matches the 125 mm bore standard. It handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, giving a usable range of 100 to 200 mm without changing the cylinder itself. The retract end remains fixed. A built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position detection. For high-heat environments up to 150 C, a Viton H seal option is available, and the two-way piston seal ensures reliable double-acting operation.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100S Is Used
Press Fit Tuning
Dial in the exact extend stop on-site for pressing bearings, allowing precise depth control from 100 to 200 mm without swapping cylinders.
Transfer Diverter
Adjust the extend length to route different package sizes on a conveyor line, fine-tuning the diverter arm position to match product widths.
Pallet Stop Gate
Set the exact pallet stop height on the fly, shortening the stroke by up to 100 mm to accommodate various pallet configurations.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100S the Right Cylinder?
When sizing this 125 mm bore unit, 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 yields 10053 N of push at 0.5 MPa for heavier loads. The adjustable stroke is highly useful when you want to fine-tune end positions on-site or share a single spare cylinder across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet allows for direct sensor mounting. Because the nominal stroke is 200 mm, side loads are minimal, but always guide the rod to prevent 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 SGCJ125X200-100S FAQ
This 125 mm bore cylinder features a G1/2 port and a 32 mm rod. It delivers 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 max of 1251 kgf at 1.0 MPa.
The -100 code provides an external adjuster that shortens the extend stroke by up to 100 mm on-site. The usable extend range is 100 to 200 mm, with 200 mm being the maximum. The retract end is fixed, and this stop mechanism is not a load lock.
