Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGCJ125X1000-100
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminium barrel for high structural rigidity. The G1/2 port feeds the 32 mm rod, and a two-way piston seal ensures reliable pressure containment during heavy cycles.
The external adjuster lets you shorten the extend stroke on site by up to 100 mm, meaning the usable extend range is 900-1000 mm while the retract end stays fixed. This allows fine-tuning of the end position without changing the cylinder itself. Handling about 3682 N of real work, it can lift roughly 313 kg vertically with a 2:1 margin. Note this non-magnet SKU cannot take a sensor; you need the -S variant for CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100 Is Used
Heavy Material Transfer
Pushes loaded pallets along a transfer line, using the 100 mm adjuster to dial in the exact stopping distance for different carton sizes without repositioning the cylinder.
Long-Press Forming
Provides 6136 N of downward clamping force on large composite sheets, fine-tuning the extend end position to compensate for varying material thicknesses on the fly.
Automated Warehousing
Actuates heavy lifting gates where the full 1000 mm stroke is occasionally too long, allowing operators to mechanically limit the extend window by 100 mm for safe clearance.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100 the Right Cylinder?
When sizing this 125 mm bore, stepping down is rarely an option as it is the smallest in the SGCJ family, but stepping up to the 160 mm bore increases push force at 0.5 MPa to 10053 N. The 100 mm adjustable window is highly useful for sharing one spare across stroke variants or tuning end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because the 1000 mm stroke is long, you must use external guides to prevent rod bending and manage side loads. Without a -S suffix, this cylinder cannot accept magnetic sensors.
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 SGCJ125X1000-100 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 maximum force of 1251 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke on site by up to 100 mm, giving a usable extend range of 900-1000 mm from the 1000 mm nominal maximum. The retract end is fixed. This mechanism only sets the end position and does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load on air loss.
