Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGCJ125X150-100
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 structural rigidity. The G1/2 port feeds a 32 mm rod with an M27x2.0 thread, and the two-way piston seal ensures reliable pressure containment. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, dropping the usable forward travel from the 150 mm maximum down to 50 mm without changing the physical mount. The retract end remains fixed. Because this SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 C, a Viton H seal option is available instead of the standard TPU.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100 Is Used
Press Fit Tuning
Dial in the exact insertion depth of a bearing press by shortening the extend stroke up to 100 mm on-site, ensuring perfect seating without repositioning the machine.
Transfer Stopper Height
Adjust the forward stop position of a pneumatic gate on the fly to accommodate different package sizes on the same line using the external adjuster.
Pallet Positioning
Fine-tune the push-off distance when transferring pallets between rollers, using the 50 to 150 mm usable extend window to handle varied pallet overhangs.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-100 the Right Cylinder?
When sizing this unit, the smaller 160 mm bore jumps to 10053 N of push at 0.5 MPa, while the 125 mm bore sits at the lower edge of the large-bore range. The 100 mm adjustment window is highly useful when you need to fine-tune end positions across shared spares or dial in a precise stroke without swapping cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. This non-magnet version cannot host position sensors. Since the nominal stroke is under 500 mm, side-load guide concerns are minimal, but always verify rod alignment. Note that the air cushion only decelerates the piston; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads.
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 SGCJ125X150-100 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100 mm on-site, giving a usable forward travel range of 50 to 150 mm. The nominal 150 mm stroke is the maximum, and the retract end is fixed. The stop sets the end position and does not lock the load.
