About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-40
The AirTAC SAIJ160X225-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, providing a usable travel window of 185 to 225 mm. Delivering a substantial 18095N push force at 0.9 MPa, this 160 mm bore actuator handles heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features a PT tapered G3/4 port. The rear mechanical stopper allows precise end-position tuning during commissioning without adding external stops. It supports a speed range of 30-500 mm/s and includes adjustable air cushions at both ends to manage heavy impact loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-40 Is Used
Heavy Press Tuning
Dial in the exact 185-225 mm end position for heavy pressing or forming tasks during machine setup without swapping actuators.
Product Changeover
Quickly adapt the stroke length on packaging lines when product dimensions change, using the 40 mm rear adjustment range.
Robust Positioning
Leverage the 18095N push force and SUS304 rod for heavy-duty material handling in washdown or corrosive environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-40 the Right Cylinder?
Select this 160 mm bore model when an application demands high thrust, such as 14074N push at 0.7 MPa, alongside a variable end-stop. If the 225 mm nominal stroke is too long, the 40 mm adjuster trims it back precisely. For lower force needs, stepping down to a 125 mm bore yields 11045N push at 0.9 MPa. To replace an ISO 15552 cylinder, match the 160 mm bore, 225 mm stroke, 40 mm adjustment, PT G3/4 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting. Since this is a 225 mm stroke, an external guide is recommended to manage side loads. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air, use an SAIL or BSAI cylinder.
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 SAIJ160BX225-40 FAQ
At 0.9 MPa operating pressure, 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 acts as a mechanical stop that lets you shorten the 225 mm nominal stroke by up to 40 mm, creating a 185-225 mm travel window. It only sets the end position; it does not lock the load without live air pressure.
