About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-30
The AirTAC SAIJ32X70-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 40-70 mm usable travel window by trimming up to 30 mm off the 70 mm nominal stroke, allowing precise end-position tuning during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and has a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, though this non-magnet version does not support position sensing. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-30 Is Used
Machine Setup Tuning
Dial in the exact 40-70 mm retract position during machine commissioning without swapping cylinders or adding external stops.
Product Changeover
Quickly adjust the end-stop to accommodate new product sizes on a packaging line, minimizing downtime.
Light-Duty Positioning
Handle precise clamping or positioning tasks using the 402 N push force, leveraging the fine stroke adjustment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-30 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and a highly adjustable end-stop within a 40-70 mm window. If your application requires less force, stepping down is not an option here as 32 mm is the smallest size, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder locks you into one exact dimension. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using a reduced set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Ensure you specify the PT port thread, SUS304 rod material, and the 30 mm adjustment range when replacing a standard ISO cylinder.

- ✓ 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 SAIJ32BX70-30 FAQ
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 reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke. For this model, it creates a usable travel window of 40 to 70 mm from the 70 mm nominal stroke. Note that this adjuster is a stop, not a lock, and cannot hold a load without live air pressure.
