About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-50
The AirTAC SAIJ200X150-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 100 to 150 mm, allowing you to dial back the nominal 150 mm stroke by up to 50 mm during commissioning. Belonging to the highest force class, it delivers up to 28274 N of push force at 0.9 MPa, making it suitable for heavy-duty pressing and handling.
This model features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The rear stopper mechanism lets you fine-tune the end position without adding external stops, though it acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-50 Is Used
Variable Press End-Stops
Dial in the exact 100 to 150 mm travel window for heavy pressing tasks without swapping cylinders or adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract position by up to 50 mm on automated lines to accommodate different product dimensions during setup.
Heavy Machine Commissioning
Fine-tune the end-of-stroke position on large equipment during installation, leveraging the 3204 kgf max force for robust actuation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-50 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme thrust, such as 21991 N at 0.7 MPa. If you need less force, stepping down to a 160 mm bore yields 14074 N at the same pressure. The 50 mm adjustment range is ideal for machines that require variable end-stops or product-size changeovers, providing setup flexibility that a fixed-stroke SAI cylinder cannot match. Because the stroke is 150 mm, side-loading is minimal, but long unsupported loads should still use an external guide. For load-holding without live air, use a SAIL or BSAI cylinder instead of relying on this adjuster. 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 SAIJ200 Adjustable Cylinder SAIJ200BX150-50 FAQ
At 0.9 MPa, this 200 mm bore cylinder delivers a push force of 28274 N and a pull force of 15080 N. It reaches a maximum force of 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 150 mm down to 100 mm. This creates a 100 to 150 mm usable window for fine-tuning end positions at commissioning.
