About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX35-10S
The AirTAC SAIJ50X35-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 25 to 35 mm for precise end-position tuning. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for compact mid-range actuation. The extruded aluminum barrel includes sensor grooves on both sides, and this specific SKU features an SUS420J2 stainless steel rod for enhanced corrosion resistance.
This model utilizes PT tapered ports and includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The rear adjustment screw acts purely as a mechanical stop to trim the retract stroke; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX35-10S Is Used
Stroke Calibration
Dial in the exact 25-35 mm retract end-stop during machine commissioning to perfect product seating without swapping cylinders.
Product Changeover
Quickly reposition the rear stopper for varying component sizes on a single line, reducing setup time between production runs.
Sensor Integration
Utilize the built-in magnet with DMSE solid-state sensors to confirm the adjusted end-position in automated assembly equipment.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX35-10S the Right Cylinder?
Choose this 50 mm bore when a 40 mm bore (628 N push at 0.5 MPa) lacks sufficient thrust but a 63 mm bore (1559 N) is physically too large. The adjustable 25-35 mm travel window is ideal for applications requiring exact end-stop calibration during commissioning without adding external stops. With a short 35 mm stroke, side-loading is minimal, though the M16x1.5 rod thread handles standard operational stresses well. When replacing an ISO 15552 cylinder, match the 50 mm bore, 35 mm stroke, 10 mm adjustment, PT ports, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ50 Adjustable Cylinder SAIJ50AX35-10S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 200 kgf.
The rear adjuster screw lets you mechanically shorten the 35 mm nominal stroke by up to 10 mm, creating a usable travel window of 25 to 35 mm. It functions as a physical stop and does not lock the load without live air.
