Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-30
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-30 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 175mm 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 SGCJ125X175-30
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster to fine-tune the extend end position on-site. Four steel tie rods clamp the aluminum barrel to the covers, yielding a rigid structure that drops into existing ISO 15552 mounting interface fixtures. The G1/2 port feeds the 32 mm piston rod, and a 40 mm adjustable air cushion decelerates the payload at both ends.
The -30 code denotes a 30 mm extend-shortening window, meaning your usable forward stroke spans 145 to 175 mm while the retract end remains fixed. This on-site tuning lets you share one spare across multiple stroke variants without buying new cylinders. Handling about 3682 N of real work, it lifts roughly 313 kg vertically with a 2:1 margin. Note this non-magnet SKU cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-30 Is Used
Press Tonnage Trimming
Dial in the exact 145 to 175 mm extend reach to contact a workpiece precisely, using the external adjuster to compensate for varying material thicknesses without repositioning the cylinder.
Divertor Gate Calibration
Fine-tune the extend stroke on-site to set the exact diverting angle for changing package sizes, ensuring positive routing without over-traveling the gate mechanism.
Pallet Stop Adjustment
Shorten the forward stroke by up to 30 mm to create variable stopping positions for mixed pallet depths, allowing quick changeovers on the packaging line.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X175-30 the Right Cylinder?
When sizing, the neighboring 160 mm bore jumps to 10053 N push at 0.5 MPa, while stepping down is not an option as 125 mm is the series minimum. The adjustable stroke shines when you need to dial in end positions after installation or want a shared spare for slightly different machine setups. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-S model, it cannot accept magnetic sensors. For any stroke over 500 mm, 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 SGCJ125X175-30 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it yields 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The nominal 175 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable forward range of 145 to 175 mm. The retract end is fixed, and the adjuster only sets the end position without holding the load.
