About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX230-75
The AirTAC SAIJ50X230-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective travel window of 155 to 230 mm. Delivering 982 N of push thrust at 0.5 MPa, it bridges the gap between smaller 40 mm bores and heavier 63 mm units. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The rear stopper screw allows precise end-position tuning at commissioning without swapping cylinders, though it acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX230-75 Is Used
Variable End-Stop Positioning
Dial in exact retraction distances between 155 and 230 mm during machine commissioning to accommodate varying product widths without external stopper blocks.
Product Changeover Systems
Quickly adjust the effective stroke on packaging conveyors when switching between different package sizes, reducing setup downtime significantly.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable double-acting motion in manufacturing areas exposed to washdowns or corrosive agents.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX230-75 the Right Cylinder?
Choose this 50 mm bore when an application requires moderate force, such as the 982 N push thrust at 0.5 MPa, but does not need the full 1559 N output of a 63 mm unit. The 75 mm adjustment range is particularly useful for product changeovers on a packaging line, allowing operators to dial back the stroke from 230 mm down to 155 mm without installing external physical stops.
Because the 230 mm stroke exceeds 200 mm, ensure adequate side-load protection by using an external guide rail to prevent rod binding. This cylinder uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. If pneumatic load-holding is required without live pressure, select an SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
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 SAIJ50BX230-75 FAQ
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 75 mm, providing a usable travel window of 155 to 230 mm. This stopper only sets the end position and deceleration; it does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the 50 mm bore generates 982 N of push thrust and 825 N of pull thrust. It supports a standard operating speed range of 30-800 mm/s and features PT tapered port threads.
