About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX95-40
The AirTAC SAIJ160X95-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers robust thrust, generating 10053N push and 9425N pull force at 0.5 MPa. Equipped with a SUS304 stainless steel rod, it provides excellent corrosion resistance for demanding environments.
The integrated rear stopper allows you to shorten the effective travel, creating a 55-95 mm usable window from the 95 mm nominal stroke. This mechanism enables fine end-position tuning at commissioning without adding external stops. The adjuster acts solely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX95-40 Is Used
End-Position Tuning
Dial in the exact retract position within the 55-95 mm window during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adapt the stroke length on packaging lines when switching to a different product size that requires a shorter travel distance.
Machine Setup
Use the rear stopper to set precise physical limits during initial equipment setup, ensuring repeatable mechanical positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX95-40 the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (3927N push at 0.5 MPa) lacks the necessary force, or step down if a 125 mm bore (6136N) is sufficient. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers. To replace an ISO 15552 cylinder, match the 160 mm bore, 95 mm stroke, 40 mm adjustment, PT tapered ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. For load-holding without live pressure, use an external rod lock or pilot-operated check valve, as this cylinder lacks a lock.
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 SAIJ160BX95-40 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N.
The rear adjuster acts as a mechanical stop that trims the 95 mm nominal stroke back by up to 40 mm, providing a usable travel window of 55 to 95 mm. It functions as a travel stop, not a lock, so it cannot hold the load without continuous air pressure.
