About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX30-30S
The AirTAC SAIJ50X30-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 982N of push force at 0.5MPa and features a 30mm nominal stroke that can be dialed back by up to 30mm, providing a 0-30mm usable travel window for exact end-position tuning. The SUS304 stainless steel rod offers high corrosion resistance, and the integrated magnet supports CMSE reed and DMSE electronic sensors.
This adjustable-stroke design allows you to fine-tune the retract position at commissioning without swapping the cylinder or adding external stops. It uses a G1/4 port and includes variable air cushions at both ends. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX30-30S Is Used
Precision End-Stop Tuning
Dial in the exact 0-30mm retract position during machine commissioning to achieve precise clamping without mechanical shims.
Product Size Changeover
Quickly adjust the cylinder travel window on packaging lines when switching between different product heights.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod for reliable positioning in light manufacturing environments requiring high cleanliness.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX30-30S the Right Cylinder?
Choose this 50mm bore when an application requires 982N push force at 0.5MPa, stepping up from a 40mm bore that provides 628N. The adjustable 0-30mm window is ideal for setups needing precise end-stop tuning during product changeovers. For load-holding without live air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock or a related SAIL pneumatic lock cylinder.
To match this ISO 15552 interchangeable cylinder, specify a 50mm bore, 30mm stroke, 30mm adjustment, PT tapered ports, and the -S magnet. Because the stroke is under 300mm, side-load stress is minimal, but always ensure the M16x1.5 rod thread is properly aligned to avoid binding.
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 SAIJ50BX30-30S FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 30mm. This creates a 0-30mm usable travel window from the 30mm nominal stroke, enabling fine-tuning of the end position without replacing the cylinder.
At 0.5MPa operating pressure, the SAIJ50X30-30-S generates 982N of push force and 825N of pull force. It can reach up to 1767N push force at 0.9MPa.
