About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-10S
The AirTAC SAIJ32X155-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 145-155 mm usable travel window, allowing you to dial back the 155 mm nominal stroke by up to 10 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster acts purely as a mechanical stop—it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-10S Is Used
Machine Setup Tuning
Dial in the exact 145-155 mm end position during initial commissioning without physically swapping cylinders or adding external stop blocks.
Product Changeover
Quickly adapt the effective stroke on automated lines when handling slightly different product sizes that require a trimmed retraction distance.
Light-Duty Positioning
Utilize the 402 N push force and SUS304 stainless steel rod for precise, corrosion-resistant component placement in varied environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-10S the Right Cylinder?
Choose this 32 mm bore when 402 N of push force at 0.5 MPa is sufficient, or step up to the 40 mm bore if your application requires 628 N. An adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder or bolt on external stoppers. For load-holding without continuous air pressure, use a SAIL or BSAI cylinder instead, as the SAIJ rear screw is only a travel stop.
To match this ISO 15552 cylinder, specify a 32 mm bore, 155 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The 155 mm stroke is under the 300 mm threshold, but the 12 mm rod and M10x1.25 thread still require attention to side-load if the piston rod is subjected to off-center forces.
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 SAIJ32BX155-10S 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 the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the effective travel by up to 10 mm, creating a 145-155 mm usable window. It acts as a mechanical stop to fine-tune the end position and does not function as a lock or brake.
