About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-100
The AirTAC SAIJ32X280-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a usable stroke window of 180 to 280 mm, providing massive flexibility for product changeovers without swapping the actuator. In its base 32 mm bore configuration, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Equipped with a SUS304 stainless steel rod and PT tapered ports, this extruded aluminum profile cylinder is built for durability. It features variable air cushions at both ends to manage deceleration across its 30 to 800 mm/s operating speed range. The rear adjuster acts purely as a mechanical stop to set the end position, meaning it will not hold a load safely without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-100 Is Used
Product Changeovers
Leverage the 180-280 mm travel window to quickly adapt end-stops for different sized products on the same line without changing the cylinder.
Commissioning Calibration
Fine-tune the exact retract position during machine setup to dial in sensor alignment and tooling clearance without external shims.
Variable Sorting Stops
Adjust the stroke on the fly to act as a movable diverter or stopper gate for packages of varying heights on a conveyor.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-100 the Right Cylinder?
Choose this 32 mm bore if your application requires the 402 N push force at 0.5 MPa; stepping down is not an option in this series, but stepping up to a 40 mm bore provides 628 N if your payload increases. The 100 mm adjustment window is ideal when you need to dial in exact end positions during commissioning or shift between product sizes on the fly, avoiding the need to bolt on external stops. For load-holding without continuous air pressure, you would need to look at the SAIL or BSAI variants, as the SAIJ adjuster is not a locking mechanism.
Because the 280 mm stroke is relatively long for a 32 mm bore, the 12 mm rod should be paired with an external guide to prevent excessive side-loading and premature seal wear. This model uses a PT port thread and omits a magnet, so position sensing is not supported out of the box. It utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 Adjustable Cylinder SAIJ32 SAIJ32BX280-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the nominal 280 mm stroke by up to 100 mm, creating a usable travel range of 180 to 280 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air.
