Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 800mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20
The AirTAC SAIJ32X800-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 800 mm nominal travel back by up to 20 mm, yielding a 780-800 mm usable window for precision commissioning. It delivers 402 N of push force at 0.5 MPa and operates at speeds of 30-800 mm/s through its G1/8 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This SKU uses a SUS304 stainless steel rod for corrosion resistance and carries a 12 mm rod diameter with an M10x1.25 thread. The rear screw functions strictly as a travel stop to fine-tune the retract end-position during machine setup, meaning it cannot hold the load without live air pressure. For position holding, an external pilot-operated check valve or the SAIL/BSAI series is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20 Is Used
Machine Changeover
Dial in the 780-800 mm travel window during product size changes without replacing the cylinder or bolting on external stops.
End-Stop Calibration
Fine-tune the retract position on a long-stroke material pusher to compensate for mechanical tolerance variations at commissioning.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable double-acting motion in packaging lines where moisture or mild chemicals are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of thrust at 0.5 MPa; if you need greater force, stepping up to the 40 mm bore yields 628 N. The adjustable stroke is ideal for product changeovers, letting you dial in the exact end-stop without swapping cylinders or adding external stops. Because this cylinder features an 800 mm stroke, the long unsupported piston rod is susceptible to side-loading and requires an external guide to prevent premature seal wear.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 800 mm stroke, 20 mm adjustment range, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This configuration omits the -S magnet, so it does not support AirTAC CMSE or DMSE sensors without modification.
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 SAIJ32BX800-20 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds ranging from 30 to 800 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the 800 mm nominal stroke by up to 20 mm, creating a 780-800 mm usable travel window. It only sets the end position and does not lock or hold the load without continuous air pressure.
