Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGCJ125X160-40S
Generating 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 160 mm stroke remains the maximum travel, yielding a usable 120 to 160 mm extend range while the retract end stays fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the standardized ISO 15552 mounting interface guarantees dimensional interchangeability with existing large-bore fixtures.
Equipped with a G1/2 port and a 32 mm rod, the unit handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin. The -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches for precise position detection. Standard TPU seals operate from -20 to +70 C, though a Viton H option extends this range up to 150 C for high-temperature environments.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40S Is Used
Press Fit Tuning
Micro-adjust the 120 to 160 mm extend stroke on-site to set precise insertion depths for bearing press operations without changing tooling.
Pallet Stopper Gate
Act as a heavy-duty pallet stop where the exact extend position must be dialed in by 40 mm to accommodate varying load widths on a conveyor.
Sealing Head Alignment
Fine-tune the downstroke end position to apply exact clamping pressure on carton sealing heads, compensating for material thickness variations.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40S the Right Cylinder?
When sizing this bore, stepping down is not an option as 125 mm is the low edge of the SGCJ range. Stepping up to the 160 mm bore increases the 0.5 MPa push force to 10053 N if your application demands more thrust. The 40 mm adjustable window is invaluable for fine-tuning end positions on-site without physically swapping the cylinder, allowing one spare to service multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included magnet supports CMSG, DMSG, and EMSG sensors. Although the 160 mm stroke is relatively short, always guide the load to prevent side-load damage on the rod.
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 SGCJ125X160-40S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it yields 8590 N push and 8028 N pull. The theoretical maximum is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 port.
An external stop screw shortens the extend stroke on-site by up to 40 mm, giving a usable extend range of 120 to 160 mm. The nominal 160 mm stroke is the maximum travel, and the retract end remains fixed. This mechanism sets the end position but does not lock the load.
