About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-20
The AirTAC SAIJ160X290-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 18095N pull force at 0.9 MPa and provides a usable travel window of 270 to 290 mm, letting you dial back the nominal 290 mm stroke by up to 20 mm during machine setup. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model uses a SUS304 stainless steel rod for superior corrosion resistance and is fitted with PT tapered ports. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops, while the integrated air cushions manage deceleration. It is not a locking device and will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-20 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 270-290 mm window during machine commissioning without swapping cylinders or adding external shims.
Product Size Changeover
Quickly adjust the stroke by up to 20 mm to accommodate new part dimensions on a packaging or handling line.
Heavy-Duty Positioning
Move heavy fixtures using the 18095N pull force while relying on the built-in air cushions to decelerate the load smoothly at the travel end.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-20 the Right Cylinder?
Choose this 160 mm bore actuator when you need higher thrust than a 125 mm cylinder (which provides 11045N at 0.9 MPa) but want to avoid the massive 3204 kgf capacity of the 200 mm bore. The adjustable stroke is ideal for product changeovers or commissioning tweaks where a fixed-stroke SAI cylinder would require shimming or swapping. For load-holding requirements without continuous air pressure, consider the SAIL or BSAI series instead.
Because the 290 mm stroke is relatively long, the 40 mm rod should be guided externally to prevent side-load damage. This configuration includes PT tapered ports, a SUS304 stainless steel rod, and no magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Operating speed is 30-500 mm/s.
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 SAIJ160 Adjustable Cylinder SAIJ160BX290-20 FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095N and a pull force of 9425N. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from the 290 mm nominal stroke down to 270 mm. It functions as a mechanical stop for fine-tuning end positions and is not a lock, meaning the cylinder will not hold the load without live air pressure.
