About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40
The AirTAC SAIJ32X195-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 155-195 mm usable travel window from its 195 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This variant uses a SUS304 stainless steel rod for corrosion resistance and PT tapered port threads (G1/8). The rear adjustment mechanism acts purely as a travel stop to fine-tune the retract end position during commissioning without external stops. It is not a lock, so live air pressure is required to hold the load in place.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40 Is Used
Machine Changeover
Dial in the 155-195 mm retract position during product size transitions without swapping hardware or adding external stopper blocks.
End-Stop Calibration
Fine-tune the final end-of-stroke position at commissioning to compensate for mechanical tolerance stack-up in assembly fixtures.
Light-Duty Positioning
Utilize the 402 N push force at 0.5 MPa for moving small parts or actuating light clamps within a compact ISO 15552 footprint.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning on the fly, avoiding the need to physically swap a fixed-stroke SAI cylinder. If your process demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 195 mm stroke is under the 300 mm side-load threshold, the 12 mm rod handles standard loads well, though an external guide is recommended for heavy lateral masses.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 32 mm bore, 195 mm stroke, 40 mm adjustment range, PT port threads, SUS304 (B) rod material, and the required mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR brackets. For applications requiring true load-holding without continuous air pressure, consider the SAIL or BSAI series instead.

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 SAIJ32BX195-40 FAQ
The rear adjuster screw acts as an external stop, allowing you to shorten the effective stroke from 195 mm down to 155 mm. This creates a 40 mm adjustment window for fine-tuning the end position at commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
