Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGCJ125X350-100S
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder handles serious work. Its four steel tie rods clamp the aluminum barrel securely to the covers. The G1/2 port and M27x2.0 rod thread equip this 125 mm bore unit for heavy tasks. A safe working load sits around 3682 N, translating to roughly 313 kg lifted vertically with a 2:1 margin.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, giving a usable range of 250 to 350 mm without changing the cylinder. The retract end remains fixed. This model includes a piston magnet for CMSG/DMSG/EMSG sensors. Standard TPU seals work from -20 to +70 C, while a Viton H option extends heat resistance to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100S Is Used
Press Tonnage Calibration
Dial in the exact 250 to 350 mm extend reach on-site to seat pressing tools accurately without machining custom spacers.
Divertor Arm Positioning
Fine-tune the push-off distance of a sorting arm by up to 100 mm to accommodate different package widths on the line.
Pallet Stop Adjustment
Modify the stopping point for varying pallet depths directly at the machine, using the external adjuster to set the exact end position.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100S the Right Cylinder?
When sizing this unit, the 125 mm bore sits at the low edge of the SGCJ range. If your application needs less force, a smaller standard cylinder fits better, but stepping up to the 160 mm bore raises push force to 10053 N at 0.5 MPa. The adjustable stroke shines when you need to fine-tune end positions on-site or share a spare cylinder across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The built-in magnet supports CMSG/DMSG/EMSG switches. For this 350 mm stroke, 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 SGCJ125X350-100S FAQ
It pushes 6136 N and pulls 5734 N at 0.5 MPa. At 0.7 MPa, push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The 350 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, yielding a usable extend range of 250 to 350 mm. The retract end is fixed, and this stop sets position only, not a load lock.
