Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20S 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 SGCJ125X1000-20S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a 125 mm bore and a 1000 mm stroke. Four steel tie rods clamp the aluminum barrel to the covers, and the G1/2 port feeds a double-acting single-rod system. The built-in piston magnet supports CMSG, DMSG, and EMSG sensors for precise position detection.
The -20 code defines an external adjuster that shortens the extend stroke on-site by up to 20 mm, letting you fine-tune the end position without changing the cylinder. This yields a usable extend range of 980 to 1000 mm while the retract end remains fixed. It handles a safe working load of about 3682 N, which means you can lift roughly 313 kg vertically with a 2:1 margin. The standard TPU seals offer long life, though a Viton H option extends the temperature range to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20S Is Used
Transfer Line Diverter
Fine-tune the 20 mm extend window on-site to perfectly align a diverter gate on a heavy packaging conveyor without machining new stops.
Pallet Stopper Adjustment
Dial in the exact end position for a pallet stopping mechanism, accommodating varying pallet thicknesses while delivering 6136 N of holding push.
Heavy Lift Positioning
Lift loads up to 313 kg vertically with a 2:1 safety margin, using the adjustable stroke to compensate for mechanical drift over a 1000 mm travel.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-20S the Right Cylinder?
When sizing this 125 mm bore unit against its neighbors, note it provides 6136 N push at 0.5 MPa, sitting between smaller and larger bores like the 160 mm class which hits 10053 N. The adjustable stroke is ideal for sharing a spare across stroke variants or finalizing end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a 1000 mm stroke, you must use external guides to prevent rod bending and manage side loads. The -S suffix confirms the magnet is present for electronic 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 SGCJ125X1000-20S FAQ
This 125 mm bore cylinder has a G1/2 port. 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 of 1251 kgf at 1.0 MPa.
The -20 indicates an external adjuster that lets you shorten the extend stroke by up to 20 mm on-site. The nominal 1000 mm stroke is the maximum, giving a usable extend range of 980 to 1000 mm. The retract end is fixed, and this mechanism only sets the end position, meaning it does not hold the load on air loss.
