Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGCJ125X100-40S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that shortens the extend stroke on-site by up to 40 mm. The nominal 100 mm stroke serves as the maximum, letting you fine-tune the end position down to a 60 mm usable extend without swapping the unit. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the G1/2 port feeds the 32 mm rod. The built-in -S magnet supports CMSG, DMSG, and EMSG switches for precise position detection.
This double-acting single-rod actuator handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 safety margin. It is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into existing large-bore fixtures. The adjustable air cushions provide 40 mm of deceleration at each end. A plain pneumatic cylinder does not hold load on air loss; the cushion only decelerates, so fit an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40S Is Used
Press Fit Tuning
Fine-tune the 60 to 100 mm extend stroke on-site to set precise insertion depth for bearing press operations without changing the cylinder.
Transfer Stopper
Adjust the stop position on the fly for mixed product sizes on a conveyor line, using the 40 mm window to dial in the exact end point.
Pallet Positioning
Shift a pallet against a fixed wall using the 6136 N push force, tweaking the extend length to accommodate varying pallet widths.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40S the Right Cylinder?
Size this 125 mm bore against its neighbors: the 160 mm bore yields 10053 N push at 0.5 MPa for heavier demands, while the 125 mm provides 6136 N. The -40 mm adjustable window is ideal when you need on-site end-position tuning across shared spare parts or varying stroke variants. SGCJ mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix confirms the piston magnet is present for CMSG/DMSG/EMSG sensors. For any stroke at or above 500 mm, always use a guide rail to prevent side-load damage to the rod seals.
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 SGCJ125X100-40S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port.
The nominal 100 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 60 to 100 mm. The retract end remains fixed, and the stop sets end position rather than locking the load.
