About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10S
The AirTAC SAIJ160X450-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 14074N push force at 0.7 MPa and up to 18095N at 0.9 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches installed in the dual-side sensor grooves.
This specific SKU provides a 440-450 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning. The piston features a 40 mm SUS304 stainless steel rod (code B) with an M36x2 thread, paired with PT tapered port threads. The extruded aluminum barrel incorporates adjustable air cushions at both ends to manage kinetic energy, though the rear stopper only sets the end position and does not hold the load without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10S Is Used
Heavy Press Tuning
Dial in the exact 440-450 mm end-stop on heavy forming presses to compensate for tooling wear without swapping the actuator.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm during automated line changeovers to accommodate slightly different product sizes.
Large Fixture Clamping
Secure large aerospace or automotive components using the 18095N push force, relying on the SUS304 rod for corrosion resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10S the Right Cylinder?
Selecting this 160 mm bore cylinder is appropriate when an application demands high force, such as 10053N push at 0.5 MPa, combined with precise end-position tuning. If your setup requires less thrust, stepping down to a 125 mm bore yields 6136N at 0.5 MPa. Conversely, moving up to a 200 mm bore provides 15708N at 0.5 MPa. The adjustable-stroke design is favored over a fixed SAI cylinder when you need a variable end-stop to dial in the exact travel without adding external stops.
Because the 450 mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the 40 mm rod despite its robust M36x2 thread. To replace an ISO 15552 cylinder, match the 160 mm bore, 450 mm stroke, -10 adjustment, PT ports, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live air pressure, use a SAIL or BSAI cylinder instead, as the SAIJ adjuster is a stop, not 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 SAIJ160BX450-10S FAQ
At 0.5 MPa it provides 10053N push and 9425N pull force. At 0.9 MPa, the push force reaches 18095N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 450 mm nominal stroke by up to 10 mm, creating a 440-450 mm travel window. It sets the end position but does not lock the load without live air.
