About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-40
The AirTAC SAIJ160X145-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 105 to 145 mm, allowing you to dial back the nominal 145 mm stroke by up to 40 mm during commissioning. This 160 mm bore generates a substantial 14074 N of push force at 0.7 MPa, making it well-suited for heavy-duty positioning tasks.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The carbon steel piston rod features an M36x2 thread, and the body uses a PT G3/4 tapered port. Unlike a tie-rod design, this profile cylinder accepts a specific mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-40 Is Used
Heavy Press Operations
Provides 14074 N of push force at 0.7 MPa for heavy pressing, with the 40 mm adjustment allowing precise tuning of the pressing depth without changing hardware.
Product Changeover
Quickly adapt the end stop from 105 to 145 mm during production line changeovers to accommodate different material lengths on the fly.
Large Material Positioning
Uses the robust M36x2 threaded carbon steel rod to move heavy jigs into place, relying on the external guide to prevent side-load damage.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-40 the Right Cylinder?
Select this 160 mm bore model when your application demands high force, delivering 10053 N of push thrust even at a conservative 0.5 MPa. If you need less force, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa, while stepping up to a 200 mm bore provides 15708 N at the same pressure. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without swapping the cylinder or adding external stops.
When matching this for an ISO 15552 replacement, verify the 145 mm stroke, 40 mm adjustment range, PT G3/4 port, and the chosen mounting bracket. Because the stroke is 145 mm, side loads are moderate, but always ensure adequate external guiding for heavy loads. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.
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 SAIJ160X145-40 FAQ
At 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 13174 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 2050 kgf of push force.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from its nominal 145 mm down to 105 mm. This allows for precise end-position tuning during commissioning without needing external stops or a different cylinder.
