About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-20
The AirTAC SAIJ160X300-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 280-300 mm usable travel window. Delivering 14074 N of push force at 0.7 MPa, it handles heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides for straightforward mounting of CMSE or DMSE switches.
This unit uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw allows precise end-position tuning during commissioning without adding external stops. Note that the adjuster acts strictly as a travel stop, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-20 Is Used
Heavy Press Positioning
Dial in the exact 280-300 mm end-stop for large presses during setup, ensuring precise material contact without external shims.
Product Changeover
Quickly adjust the stroke window on packaging lines when switching to different sized pallets or products.
Heavy-Duty Assembly
Provide high push force (up to 18095 N at 0.9 MPa) for joining heavy components while retaining the flexibility to tune the final end position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-20 the Right Cylinder?
Choose this 160 mm bore when the 100 mm class (5497 N push at 0.7 MPa) is insufficient for your heavy loads. The 20 mm adjustment range is ideal for fine-tuning end stops during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. Because the 300 mm stroke is substantial, an external guide is recommended to manage side loads on the 40 mm rod.
For an exact ISO 15552 replacement, match the 160 mm bore, 300 mm stroke, 20 mm adjustment, PT port thread, SUS304 rod material, and no-magnet configuration. If your application requires the cylinder to hold a load without live air pressure, select a SAIL or BSAI series cylinder instead, as the SAIJ adjuster does not lock the rod.
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 SAIJ160BX300-20 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 13274 N of pull force. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 300 mm nominal stroke by up to 20 mm, giving a usable travel window of 280-300 mm. This stopper fine-tunes the retract end position but does not lock or hold the load without continuous air pressure.
