About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX35-20S
The AirTAC SAIJ200X35-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N at 0.5MPa, while its SUS304 stainless steel rod provides superior corrosion resistance. The integrated -S magnet enables position feedback via CMSE reed or DMSE electronic sensors.
This specific SKU features a 35mm nominal stroke paired with a 20mm adjustment range, creating a fine-tuning usable travel window of 15-35mm. The extruded aluminum barrel includes sensor grooves on both sides, and the rear screw acts purely as a travel stop for end-position tuning, not a load lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX35-20S Is Used
Heavy Press Fitting
Dial in the exact 15-35mm travel window during setup to seat large bearings precisely without over-traveling.
Short-Stroke Clamping
Adjust the end-stop on the fly for product changeovers, ensuring massive 15708N clamping force is applied accurately.
End-Stop Calibration
Fine-tune the retraction point during machine commissioning using the rear screw, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX35-20S the Right Cylinder?
Select this 200mm bore cylinder when an application demands extreme force in a very short stroke, requiring precise end-position calibration without swapping cylinders. If 15708N push force at 0.5MPa exceeds your requirement, stepping down to the 160mm bore yields 10053N. The -20mm adjuster allows exact end-stop tuning during commissioning, whereas a fixed SAI cylinder locks you into a single position.
Because the stroke is 35mm, side-load risks are minimal, but the 40mm rod diameter handles high axial stress well. The rear adjuster only sets the travel end and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. This model features PT tapered ports and the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAIJ200BX35-20S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum of 3204 kgf at 1.0MPa.
The rear adjuster screw allows you to trim the effective stroke back by up to 20mm, creating a usable travel window of 15-35mm. This stopper sets the travel end but does not lock the load without continuous air pressure.
