Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 175mm 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 SGCJ125X175-10S
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 rigidity. The built-in piston magnet supports CMSG, DMSG and EMSG sensors for precise position detection. A G1/2 port supplies air to the 32 mm rod, while adjustable 40 mm cushions absorb impact at both ends.
An external adjuster lets you shorten the extend stroke on site by up to 10 mm, meaning the usable extension runs 165 to 175 mm without changing the cylinder itself. This on-site tuning is ideal for dialling in exact end positions. It handles a safe working load of about 3682 N, which means you can vertically lift roughly 313 kg with a 2:1 safety margin. The standard TPU seals operate from -20 to +70 C, though a Viton H option extends this to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-10S Is Used
Press Stroke Tuning
Dial in the exact 165 to 175 mm extend position on a light-duty assembly press without machining new spacers.
Diverter Gate Adjustment
Fine-tune the extend stop on a package routing gate to accommodate varying product sizes on the fly.
Pallet Stop Positioning
Set a precise pallet stop location on a heavy-duty roller conveyor and readjust it easily when line formats change.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-10S the Right Cylinder?
When sizing this unit, the smaller 160 mm bore offers significantly more thrust if your application outgrows the 125 mm class, pushing 10053 N at 0.5 MPa. Conversely, if your load is lighter, dropping down reveals that the 125 mm bore is already a substantial step up from smaller profile cylinders. The 10 mm adjustable window is highly useful when you need to share a spare cylinder across multiple stroke variants or fine-tune a machine stop. It supports FA, LB, TC, FTC, TCM1 and TCM2 mountings. Because this 175 mm stroke is under 500 mm, side-load risks are lower, but you should still guide the rod end to prevent binding. The included -S magnet allows direct mounting of CMSG, DMSG or EMSG switches.
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 SGCJ125X175-10S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and a 32 mm piston rod.
The nominal 175 mm stroke is the maximum extension. An external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 165 to 175 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
