Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X25-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X25-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 25mm 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 SGCJ125X25-10S
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 aluminum barrel for high rigidity. The G1/2 port feeds the 125 mm bore, generating a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
As an adjustable-stroke variant, an external stop screw lets you shorten the extend stroke on-site by up to 10 mm from the 25 mm nominal maximum, while the retract end remains fixed. The built-in -S magnet supports CMSG, DMSG, and EMSG sensors for position feedback, and the default TPU seals handle -20 to +70 C, with a Viton H option for 0-150 C environments.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X25-10S Is Used
Short-Stroke Clamping
Provides 6136 N of precise clamping force where the final 15 to 25 mm of extend travel must be dialed in exactly on-site using the external adjuster.
Transfer Stopper Gate
Acts as a heavy 125 mm bore stop gate on a conveyor, using the 10 mm adjuster window to fine-tune the blocking position for different product sizes.
Press Fit Positioning
Drives a short press fit operation, relying on the CMSG sensor feedback and the adjustable stop screw to set the exact 15 mm insertion depth.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X25-10S the Right Cylinder?
When sizing this unit, the 125 mm bore sits at the low edge of the SGCJ family, offering 6136 N push at 0.5 MPa, whereas stepping up to the 160 mm bore yields 10053 N. The adjustable stroke is ideal for sharing a spare across stroke variants or fine-tuning the end position without swapping the cylinder. It supports FA, LB, TC, FTC, TCM1, and TCM2 mounts, and the -S magnet enables switch tracking. Even at 25 mm stroke, always guide the load to prevent side-load damage.
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 SGCJ125X25-10S FAQ
This 125 mm bore cylinder features a G1/2 port and a 32 mm rod. 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 force of 1251 kgf at 1.0 MPa.
The 25 mm nominal stroke is the maximum extend length. An external adjuster allows you to shorten the extend stroke by up to 10 mm on-site, giving a usable range of 15 to 25 mm, while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
