About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-30S
The AirTAC SAIJ32X650-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This creates a usable stroke window of 620 to 650 mm, enabling precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push force at 0.5 MPa and utilizes a G1/8 port.
This variant includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries an -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop and deceleration setup, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-30S Is Used
Machine Changeover
Dial in the 620-650 mm travel window during product size transitions without bolting on new external stops or changing the cylinder.
Variable End-Stop Setup
Use the 30 mm rear adjuster to fine-tune the retract position precisely during commissioning for delicate pick-and-place operations.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod and double-acting thrust for reliable motion in washdown or mildly corrosive manufacturing cells.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-30S the Right Cylinder?
Choose this 32 mm bore when an application requires a 620-650 mm adjustable stroke and moderate thrust up to 402 N at 0.5 MPa. If your setup demands higher force, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. The adjustable stroke is ideal for machine changeovers or product-size variations where the exact end-stop needs fine-tuning, unlike a fixed-stroke SAI cylinder.
Because the stroke is 650 mm, the 12 mm rod and M10x1.25 thread will experience greater leverage on side loads, so an external guide is recommended to prevent binding. For position holding without continuous air pressure, the adjuster here is not a lock; you should explore an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX650-30S 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 operating pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the 650 mm nominal stroke by up to 30 mm, creating a usable travel window of 620 to 650 mm. This stopper only sets the travel end and deceleration; it does not lock or hold the load without live air pressure.
