About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30S
The AirTAC SAIJ160X800-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 770 to 800 mm without swapping components. It delivers substantial thrust, offering 14074N of push force and 9425N of pull force at 0.7 MPa. This makes it highly suitable for heavy-duty positioning tasks requiring exact end-stop calibration.
Equipped with a SUS304 stainless steel rod and a PT tapered port, this unit also includes an integrated magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides dual sensor grooves, and the adjustable stopper functions purely as a travel end-limit, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30S Is Used
Heavy Press Tuning
Dial in the exact 770-800mm end-stop for heavy press operations, allowing precise material deflection compensation during machine commissioning.
Product Changeover Stops
Adjust the retract position on the fly to accommodate different product lengths on a conveyor line without physically replacing the cylinder.
Large Assembly Fixtures
Leverage the 14074N push force to move heavy pallets into fixtures, using the rear screw to perfectly align the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30S the Right Cylinder?
Select this 160 mm bore when an application requires heavy force that smaller bores cannot provide; stepping down to a 125 mm bore would reduce push force at 0.7 MPa to 8590N. The 30 mm adjustment range is ideal for product changeovers or commissioning setups where the exact end-position needs variable tuning. For applications requiring true load-holding without live air pressure, a standard SAIJ is insufficient; consider an AirTAC SAIL or BSAI series cylinder instead.
Because this model features an 800 mm stroke, the 40 mm diameter rod is subject to increased side-load risks. Always use an external guide rail to prevent rod binding over this long travel distance. When replacing an ISO 15552 cylinder, match the 160 mm bore, 800 mm stroke, 30 mm adjustment, PT G3/4 port, and the -S magnet requirement.
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 SAIJ160BX800-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074N of push force and 9425N of pull force. It can reach a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 770 to 800 mm for fine-tuning end positions without external stops.
