About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20S
The AirTAC SAIJ200X130-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal stroke of 130 mm and a 20 mm adjustment range, it provides a usable travel window of 110 to 130 mm. This allows precise end-position tuning at commissioning without adding external stops. It delivers substantial thrust, offering 15708 N of push force and 15080 N of pull force at 0.5 MPa operating pressure.
This variant includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and comes with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides. It uses a PT G3/4 port and operates at speeds between 30 and 500 mm/s. The rear adjuster acts solely as a travel stop for deceleration and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20S Is Used
Heavy Press Tuning
Dial in the exact 110 to 130 mm travel window during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeovers
Quickly adjust the rear stopper on packaging lines when switching product sizes, using the 20 mm adjustment range to set new end positions.
Assembly Station Setup
Leverage the 15708 N push force at 0.5 MPa for heavy assembly tasks while fine-tuning the stroke end to prevent overtravel damage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application requires the maximum standard thrust class, stepping up significantly from the 160 mm bore which provides 10053 N push at 0.5 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when you need a variable end-stop to fine-tune the travel window between 110 and 130 mm during machine setup or product changeovers. Because the total travel is 130 mm, an external guide is recommended to manage side loads, despite the robust 40 mm rod diameter and M36x2 thread.
For drop-in ISO 15552 interchangeability, match the 200 mm bore, 130 mm stroke, 20 mm adjustment, PT G3/4 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your process requires true load holding without continuous air pressure, this cylinder is not a lock; consider the SAIL or BSAI series instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-20S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster allows you to shorten the effective stroke from its nominal 130 mm down to 110 mm. This creates a 110-130 mm travel window for fine-tuning the end position at commissioning. The adjuster acts as a stop and does not lock the load without live air.
