About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX300-10
The AirTAC SAIJ200X300-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a substantial 15708N of thrust at 0.5 MPa and uses a robust 40mm SUS304 stainless steel rod with PT tapered G3/4 ports. The integrated rear stopper allows you to trim the nominal 300mm travel back by up to 10mm, creating a precise 290-300mm usable window for fine-tuning end positions at commissioning.
Because the adjuster acts solely as a mechanical stop on the retract end, it decelerates the stroke but does not hold the load without live air pressure. For position holding, external pilot-operated check valves or an AirTAC SAIL locking cylinder are required. The extruded aluminum barrel includes sensor grooves on both sides, and while no magnet is specified here, adding one enables CMSE reed and DMSE solid-state sensor tracking.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX300-10 Is Used
Heavy Press Tuning
Dial in the exact 290-300mm end position on large metal forming presses to compensate for tooling wear without disassembling the line.
Product Changeover
Quickly adjust the retract stop for varying package sizes on heavy-duty material handling conveyors during production line transitions.
Machine Setup
Fine-tune the stroke window during initial commissioning of large automation equipment to perfect timing and avoid mechanical interference.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX300-10 the Right Cylinder?
Choose this 200mm bore when 160mm falls short, delivering 15708N push force at 0.5 MPa compared to the 160mm bore's 10053N. The 10mm adjustment range is ideal for setting variable end stops during machine setup or product changeover without swapping the cylinder or adding external stops. To match this ISO 15552 replacement, specify: 200mm bore, 300mm stroke, 10mm adjust, PT G3/4 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet.
With a 300mm stroke, the 40mm SUS304 rod carries high side-load capacity, but an external guide is still recommended to prevent binding on long unsupported travels. Operating speed is 30-500mm/s, and the cylinder features variable air cushions at both ends to manage heavy impact forces.
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 SAIJ200BX300-10 FAQ
At a 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 300mm nominal stroke by up to 10mm. This creates a 290-300mm usable travel window for fine-tuning end positions without replacing the cylinder.
