About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-30S
The AirTAC SAIJ32X45-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 45 mm stroke that can be dialed back by up to 30 mm, yielding a highly versatile 15-45 mm usable travel window for exact end-position tuning. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups requiring precise mechanical stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is designed to accept CMSE reed and DMSE electronic solid-state switches in its dual-side sensor grooves. The PT tapered port threads and integrated adjustable air cushions at both ends ensure secure, leak-free fittings and smooth end-of-stroke deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-30S Is Used
Machine Setup Calibration
Dial in the exact 15 to 45 mm retract position during initial commissioning without machining new hard stops.
Product Changeover
Quickly adjust the travel end-stop on a packaging line when switching between different product sizes.
Variable End-Stop Forming
Provide precise mechanical positioning for light-duty pressing or forming tasks that require adjustable depth.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-30S the Right Cylinder?
Choose this 32 mm bore cylinder when your application demands 402 N of push force at 0.5 MPa and on-the-fly stroke adjustments. The rear stopper allows you to fine-tune the retract position during commissioning or product changeovers without swapping the cylinder or adding external stops. If your setup requires less force, stepping down to a 25 mm bore is an option, while moving up to a 40 mm bore provides 628 N of push force.
Because the rear adjuster acts strictly as a travel stop and the cushions only manage deceleration, neither will hold a load without live air pressure. For load-holding requirements without continuous air, consider an external pilot-operated check valve or explore the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX45-30S FAQ
The rear adjusting screw acts as a mechanical stopper that shortens the effective stroke. For this model, the 45 mm nominal stroke can be trimmed back by up to 30 mm, giving an actual usable travel window of 15 to 45 mm.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
