About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-20
The AirTAC SAIJ32X600-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 600 mm nominal stroke that can be fine-tuned down by up to 20 mm, giving a precise 580-600 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds between 30 and 800 mm/s.
This model uses a PT tapered port (G1/8) and includes variable air cushions at both ends to manage deceleration. The extruded aluminum barrel features sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if position feedback is later required. The rear adjuster functions strictly as a mechanical stop to set the travel end, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-20 Is Used
Changeover Calibration
Dial in the 580-600 mm travel window during machine setup to accommodate different product sizes without physically replacing the actuator.
Variable End Stops
Adjust the rear stopper precisely to alter the rejection point or push-off distance on a material handling line.
Fine Position Tuning
Trim the final 20 mm of stroke at commissioning to perfectly align tooling, avoiding the need for custom spacer shims.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-20 the Right Cylinder?
Choose this 32 mm bore when you need exact end-position tuning during commissioning or product changeovers without swapping cylinders or adding external stops. If an application requires higher thrust, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. Because this unit features a 600 mm stroke, the 12 mm rod and M10x1.25 thread should be paired with an external guide to prevent excessive side-loading on the piston.
For a direct ISO 15552 replacement match, verify the 32 mm bore, 600 mm stroke, 20 mm adjustment range, PT port thread, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that SAIJ omits the FB, CA, CB, and CR mounts. If your setup demands true load-holding without live air, an external rod lock or an AirTAC SAIL pneumatic lock cylinder is required instead.

- ✓ 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 SAIJ32BX600-20 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 mechanical screw acts as a stopper, allowing you to shorten the 600 mm nominal stroke by up to 20 mm. This creates a 580-600 mm usable travel window for fine-tuning the end position, though it does not lock the load without live air.
