Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-50
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCJ125X200-50
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder brings large-bore power to applications needing exact end-position tuning. The four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the dimensionally interchangeable ISO 15552 mounting interface drops directly into existing large-bore fixtures. It uses a G1/2 air port and an M27x2.0 piston rod.
The external adjuster lets you shorten the extend stroke on site by up to 50 mm, giving a usable range of 150 to 200 mm without changing the cylinder itself. The retract end remains fixed, while the adjustable air cushions at both ends absorb 40 mm of impact. This SKU lacks a magnet, so it cannot take CMSG, DMSG, or EMSG sensors without upgrading to the -S variant. The stop screw sets the end position; it is not a load lock, so use an external rod lock or pilot-operated check valve if you need to hold a load vertically.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-50 Is Used
Press Fit Tuning
Dial in the exact 150 to 200 mm extend position on a bearing press to accommodate different housing depths without swapping cylinders.
Transfer Stops
Adjust the stopper block extension on the fly to handle varying product lengths on a single packaging line.
Pallet Positioning
Fine-tune the extend endpoint to push pallets into exact alignment before stretch wrapping, using the 50 mm window to compensate for fixture wear.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-50 the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option as it is the smallest in the SGCJ range, but stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N. The 50 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning machine setup on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-magnet SKU, position sensing is impossible. For any stroke at or above 500 mm, always use a guide rail to prevent side-load damage to the rod seal.
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 SGCJ125X200-50 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. This translates to a safe working load of about 3682 N, or roughly 313 kg lifted vertically with a 2:1 margin.
The nominal 200 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable extend range of 150 to 200 mm. The retract end is fixed, and this stopper only sets the end position; it does not lock the load.
