About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-30
The AirTAC SAIJ100X220-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 190-220 mm usable travel window by allowing you to trim up to 30 mm off the 220 mm nominal stroke without adding external stops. Delivering a robust 7068 N of push force at 0.9 MPa, it handles heavy actuation tasks with precision.
This unit 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 it supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-30 Is Used
Machine Setup Tuning
Dial in the exact 190-220 mm end-stop position during initial commissioning to perfect a pressing operation without machining custom spacers.
Product Size Changeover
Quickly adjust the retract distance on automated lines when switching to a new product variant that requires slightly less travel.
Heavy Load Positioning
Move heavy assemblies into a workstation using the 7068 N force, tweaking the final resting position via the rear stopper screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-30 the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (offering 4523 N push at 0.9 MPa) is insufficient for your load. The adjustable stroke is ideal for product changeovers, letting you fine-tune the retract end position at commissioning rather than swapping a fixed-stroke SAI cylinder. Since the rear screw acts only as a travel stop and the air cushions manage deceleration, neither holds the load without live air; for fail-safe load holding, select a SAIL or BSAI cylinder. For a direct ISO 15552 replacement, match the 100 mm bore, 220 mm stroke, 30 mm adjust, PT G1/2 port, and mounting style.
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 SAIJ100 Adjustable Cylinder SAIJ100BX220-30 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates 7068 N of push force and 5497 N of pull force. The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 220 mm nominal stroke by up to 30 mm, creating a 190-220 mm usable travel window. It only sets the end position and does not lock the load without continuous air pressure.
