About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-50
The AirTAC SAIJ32X800-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 800 mm stroke that can be dialed back by up to 50 mm, yielding a usable travel window of 750-800 mm for precise end-position tuning. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept DMSE solid-state or CMSE reed switches if a magnet is added later. The rear adjuster acts purely as a travel stop to decelerate the end of stroke, not as a lock to hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-50 Is Used
Product Changeover
Dial in the 750-800 mm stroke window during product size transitions on a packaging line without physically replacing the actuator.
Commissioning Calibration
Fine-tune the retract end-position during initial machine setup, using the rear stopper to absorb kinetic energy rather than adding hard external stops.
Variable End Stops
Adjust the travel distance on a long-stroke sorting conveyor to accommodate different package lengths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-50 the Right Cylinder?
Choose this 32 mm bore cylinder when you need 402 N of thrust at 0.5 MPa and a highly adjustable end-stop. The 50 mm adjustment window is perfect for machine setup and product changeover, allowing you to fine-tune the travel distance without swapping the cylinder or adding external stops. If your application requires higher force, stepping up to a 40 mm bore provides 628 N of push force. For load-holding without continuous air pressure, this standard SAIJ is insufficient; consider an SAIL air-released lock or an external rod lock.
Because the stroke is 800 mm, the 12 mm rod and M10x1.25 rod thread will experience significant leverage under side loads. An external guide is strongly recommended to prevent rod bending and premature seal wear. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX800-50 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm, creating a 750-800 mm usable travel window. This stopper fine-tunes the end position and works with the air cushion to decelerate the load, but it does not lock or hold the load without live air pressure.
