About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-40
The AirTAC SAIJ32X800-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down by up to 40 mm, yielding a usable window of 760 to 800 mm. Delivering 402 N of push force at 0.5 MPa via a G1/8 port, it is built for applications requiring exact end-position tuning during commissioning without swapping hardware.
This SKU uses a SUS304 stainless steel rod for superior corrosion resistance and includes variable air cushions at both ends to decelerate the payload. The rear stopper screw sets the retract end position but does not function as a lock, meaning live air pressure is required to hold the load in place.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-40 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 760 and 800 mm during machine setup to accommodate different material thicknesses without changing the cylinder.
Product Changeover Systems
Quickly adjust the stroke end-position on packaging lines when switching to a new product size, reducing downtime and avoiding external stopper hardware.
Commissioning Fine-Tuning
Use the 40 mm rear adjuster screw to perfectly tune the end-of-stroke position during initial machine commissioning, compensating for mechanical tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-40 the Right Cylinder?
Select this 32 mm bore cylinder when your setup requires a variable end-stop for product changeovers rather than a fixed-stroke SAI model. If your application requires greater thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa. To replace an ISO 15552 cylinder, match the 32 mm bore, 800 mm stroke, 40 mm adjustment, PT tapered port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the 800 mm stroke is long, the 12 mm rod is susceptible to side-loading; an external guide rail is strongly recommended to prevent binding. For applications needing fail-safe load holding without live air, consider the SAIL or BSAI series instead, as this adjuster only stops travel.
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 SAIJ32BX800-40 FAQ
The rear adjuster acts as a travel stop, allowing you to shorten the effective stroke by up to 40 mm. This provides a usable travel window of 760 to 800 mm, which can be fine-tuned during commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, the SAIJ32X800-40 provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
