Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20 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 SGCJ125X1000-20
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder brings four steel rods clamping an aluminum barrel for heavy-duty rigidity. The G1/2 port feeds a 32 mm rod running on a two-way piston seal, yielding a safe working load around 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
The -20 code gives an external adjuster that shortens the extend stroke on-site by up to 20 mm, letting you fine-tune the end position across a 980 to 1000 mm window without swapping the cylinder. Standard TPU seals handle -20 to +70 C, while a Viton H option raises that to 150 C. Because this SKU lacks a -S suffix, it cannot accept CMSG or DMSG magnetic sensors.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20 Is Used
Press Stroke Calibration
Dial in the exact 980 to 1000 mm extend end-position on-site to accommodate varying material thicknesses without changing the cylinder mounting.
Heavy Pallet Positioning
Shift heavy loads using the 8590 N push force at 0.7 MPa, relying on the 40 mm adjustable air cushions to decelerate the 1-meter travel safely.
Long-Reach Material Descending
Lower assemblies over a 1000 mm drop with a safe vertical lift capacity near 313 kg, ensuring smooth stops via the tie-rod construction.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20 the Right Cylinder?
Size this 125 mm bore against its neighbors: step down to save air if 5734 N pull at 0.5 MPa is excessive, or step up to a 160 mm bore if you need over 10053 N. The -20 mm adjustable window is ideal for sharing one spare across multiple stroke variants or dialing in end positions on-site. Mount via FA, LB, TC, FTC, TCM1, or TCM2 brackets. At 1000 mm, long-stroke rod-bending is a real risk, so use an external guide to prevent side loads. Note that a plain cylinder drifts on air loss, so fit an external rod lock for held loads.
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 SGCJ125X1000-20 FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa it yields 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The 1000 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 980 to 1000 mm. The retract end is fixed, and this stop is for positioning only, not load holding.
