Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40 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 SGCJ125X100-40
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 G1/2 port feeds the 125 mm bore, generating a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
The -40 code defines an external adjuster that shortens the extend stroke on site by up to 40 mm, letting you fine-tune the end position from 60 to 100 mm without swapping the cylinder. It shares the ISO 15552 mounting interface for direct fixture interchange, and the adjustable air cushions decelerate the piston smoothly. Note this plain SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40 Is Used
Press Stroke Tuning
Dial in the exact 60 to 100 mm extend contact point on a light-duty assembly press without machining new spacers.
Diverter Gate Adjustment
Fine-tune the actuation length of a sorting gate on-site to accommodate different package sizes on the fly.
Pallet Stop Positioning
Set a precise stop location for varying pallet depths, relying on the 6136 N thrust to halt incoming loads securely.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-40 the Right Cylinder?
Size this 125 mm bore against the 160 mm option, which jumps to 10053 N of push at 0.5 MPa, or drop down if lower force is acceptable. The 40 mm adjustable window is ideal when you need to synchronise end positions across multiple jigs or share spares across stroke variants. Standard mounts include FA, LB, TC, FTC, TCM1 and TCM2. Because this is a non-magnetised SKU, you cannot fit position sensors; add the -S suffix for CMSG/DMSG/EMSG switch readiness. For any stroke over 500 mm, always use a guide rail 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 SGCJ125X100-40 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 of 1251 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke by up to 40 mm on site, giving a usable extend range of 60 to 100 mm. The nominal 100 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position; it does not lock the load.
