Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30S 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 SGCJ125X100-30S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster to shorten the extend stroke on-site by up to 30 mm. The nominal 100 mm stroke serves as the maximum travel, allowing you to fine-tune the end position down to a 70 mm usable extend without swapping the unit. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the G1/2 port handles the 30-500 mm/s speed range.
Because the -S suffix equips the piston with a magnet, it directly supports CMSG, DMSG, and EMSG electronic or reed switches for position sensing. This bore uses a 32 mm rod with an M27x2.0 thread and 40 mm adjustable air cushions at both ends. Handling about 3682 N of real work, it can safely lift roughly 313 kg vertically with a 2:1 margin. Note that the cushion only decelerates the load; use an external rod lock or pilot-operated check valve if you need to hold position on air loss.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30S Is Used
Press Fit Tuning
Dial in the exact 70 to 100 mm extend position for seating bearings without machining custom spacers or changing the cylinder body.
Variable Length Stops
Adjust the extend stroke on-site by up to 30 mm to accommodate different package sizes on a shared pneumatic routing lane.
Pallet Positioning
Fine-tune the end stop for pallet alignment pins, relying on the 6136 N push force to shift heavy loads securely into place.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30S the Right Cylinder?
When sizing this unit, stepping down is not an option as 125 mm is the smallest SGCJ bore, but stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N if your load demands more power. The 30 mm adjustable window is highly useful for sharing a single spare cylinder across multiple stroke variants or dialing in exact end-of-stroke positioning on the machine. You can mount it using FA, LB, TC, FTC, TCM1, or TCM2 hardware. The integrated magnet allows seamless CMSG/DMSG/EMSG sensor installation. Since this is a short 100 mm stroke, side-load risks are minimal, but always guide the rod end to prevent binding.
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 SGCJ125X100-30S 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 features a 125 mm bore, a 32 mm rod, an M27x2.0 rod thread, a G1/2 port, and 40 mm adjustable air cushions.
The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 70 to 100 mm. The nominal 100 mm stroke is the maximum travel, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
