About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-10
The AirTAC SAIJ32X400-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 390-400 mm usable travel window, allowing you to dial back the 400 mm nominal stroke by up to 10 mm during machine commissioning without adding external stops. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, enabling direct mounting of CMSE reed or DMSE electronic solid-state switches if position feedback is later required. The integrated air cushions at both ends decelerate the piston to protect your tooling.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-10 Is Used
End-Position Tuning
Dial in the exact 390-400 mm retract distance during machine setup to perfect product alignment without swapping hardware.
Product Changeover
Quickly adjust the stroke stop by up to 10 mm to accommodate varying package sizes on a single conveying line.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX400-10 the Right Cylinder?
Choose this 32 mm bore when your application requires a 390-400 mm stroke window and around 402 N of thrust at 0.5 MPa. If your process demands greater clamping or lifting power, stepping up to the 40 mm bore yields 628 N of push force. Conversely, if the load is minimal, a smaller bore reduces air consumption. The adjustable rear stopper is ideal for fine-tuning the retract end-position on product changeovers, whereas a fixed-stroke SAI cylinder is preferred when the travel distance is permanently locked.
Because this cylinder lacks a magnet and uses a PT port thread, ensure your pneumatic fittings match. For a 400 mm stroke, the 12 mm rod diameter and M10x1.25 rod thread can handle moderate side loads, but an external guide rail is recommended to prevent rod binding over long unsupported travel. The rear adjuster acts strictly as a travel stop, not a load lock; if you need to hold a load vertically without live air pressure, specify an SAIL or BSAI series cylinder instead. This SAIJ model accepts a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ32BX400-10 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If higher pressure is used, the push force increases to 563 N at 0.7 MPa and 724 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 400 mm nominal stroke by up to 10 mm, creating a 390-400 mm usable travel window. This stopper only sets the end position and deceleration; it does not lock the load without continuous air pressure.
