About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-40S
The AirTAC SAIJ200X1000-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 960 to 1000 mm. Delivering massive thrust, it provides 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a maximum of 3204 kgf at 1.0 MPa. The integrated magnet supports position sensing via CMSE reed and DMSE electronic switches.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjustment screw allows precise end-position tuning at commissioning without requiring external stops or cylinder replacement.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-40S Is Used
Heavy Press Tuning
Fine-tune the 1000 mm travel end-position on large metal forming presses by dialing the rear screw back up to 40 mm, ensuring precise contact without machining custom spacers.
Product Size Changeover
Adapt long-trroke sorting or pusher mechanisms on a packaging line to different carton lengths by adjusting the stroke window from 960 to 1000 mm during routine product changeovers.
Automated Assembly Setup
Establish exact clamping or positioning depth on large automated assembly fixtures, using the rear stopper to compensate for mechanical wear or tooling variations over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-40S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application demands the highest force output, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 40 mm rear adjuster is ideal for fine-tuning long-stroke end positions during machine setup or product changeover, whereas a fixed-stroke SAI cylinder lacks this built-in flexibility. Because the nominal stroke is 1000 mm, an external guide is strongly recommended to manage side loads and prevent rod bending over this long unsupported travel distance.
This SAIJ model is dimensionally interchangeable per ISO 15552 standards. It supports a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Note that the rear adjuster and air cushions act strictly as travel stops and deceleration devices; they do not hold the load without live air. For secure load-holding without continuous pressure, consider an external rod lock or the AirTAC SAIL or BSAI series.
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 SAIJ200BX1000-40S FAQ
At 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 1000 mm nominal stroke by up to 40 mm, creating a usable travel window of 960 to 1000 mm. This stopper sets the retract end position but does not lock the load without continuous air pressure.
