About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX220-30
The AirTAC SAIJ50X220-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 190 to 220 mm usable travel window. Delivering 982 N of push force and 825 N of pull force at 0.5 MPa, it handles mid-range automation tasks with precision.
This unit uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The external rear stopper allows you to dial in the exact end position during commissioning, while the extruded aluminum barrel provides standard sensor grooves on both sides for flexible switch placement.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX220-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 190-220 mm window during machine commissioning without adding external stops.
Product Changeover
Quickly adapt the cylinder's effective stroke on automated lines when handling slightly varying product sizes.
Assembly Positioning
Use the fine adjustment capability to set precise contact points for clamping and pressing operations.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX220-30 the Right Cylinder?
Choose this 50 mm bore when 40 mm falls short at 628 N push force, but 63 mm is excessive at 1559 N. The 30 mm adjustment range is perfect for variable end-stops or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 220 mm stroke exceeds 300 mm is false, standard guiding applies, but always support side loads. Note that the rear adjuster acts as a travel stop, not a lock; for load-holding without live air, select an SAIL or BSAI cylinder.
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 SAIJ50BX220-30 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 200 kgf.
The rear adjuster screw allows you to shorten the nominal 220 mm stroke by up to 30 mm, giving an effective travel window of 190 to 220 mm. This stopper decelerates the piston at the retract end but does not lock the load without continuous air pressure.
