About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX160-30
The AirTAC SAIJ50X160-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 982N of push thrust at 0.5 MPa and provides a usable travel window of 130 to 160 mm, letting you trim the nominal 160 mm stroke by up to 30 mm during machine commissioning.
Built with a SUS304 stainless steel rod and PT tapered port threads, this model handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX160-30 Is Used
Machine Commissioning
Dial in the exact 130-160 mm end position during setup without physically swapping cylinders or machining external stop blocks.
Product Changeover
Quickly adapt the travel distance on a packaging line to accommodate varying package sizes using the 30 mm adjustment range.
End-Position Tuning
Fine-tune the retract stroke to compensate for mechanical wear or slight misalignments over the machine's lifespan.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX160-30 the Right Cylinder?
Choose this 50 mm bore when you need higher force than the 40 mm version (628N at 0.5 MPa) but want to avoid the bulk of a 63 mm cylinder. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the end stop in-place rather than swapping a fixed-stroke SAI cylinder or adding external stops.
For load-holding without continuous air pressure, this cylinder is insufficient as the rear adjuster is only a stop, not a lock; consider SAIL or BSAI models instead. This SAIJ configuration uses PT tapered ports and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. At 160 mm stroke, side-load risk is minimal, but always guide heavy loads externally.
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 SAIJ50BX160-30 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982N of push thrust and 825N of pull thrust. At the maximum 1.0 MPa pressure, it delivers up to 200 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 160 mm down to 130 mm. It trims the travel end for fine-tuning but does not lock the load without live air pressure.
