About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-30
The AirTAC SAIJ32X100-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 70-100 mm usable travel window from the 100 mm nominal stroke. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threading. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, explore the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 70-100 mm window during machine commissioning without machining external stopper blocks.
Product Changeover
Quickly adapt the stroke end-stop on a packaging line when handling slightly different carton sizes or component heights.
Light-Force Positioning
Leverage the 402 N push force at 0.5 MPa for precise, low-impact actuation in small assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-30 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops. If your process needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The 12 mm rod and M10x1.25 thread provide adequate rigidity, though any stroke over 300 mm requires an external guide to manage side loads.
To replace an ISO 15552 cylinder, match the 32 mm bore, 100 mm stroke, PT port, and the 30 mm adjustment range. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because no magnet is specified, position sensing requires adding the -S option to use CMSE reed or DMSE electronic sensors.

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 SAIJ32BX100-30 FAQ
At 0.5 MPa it provides 402 N push and 345 N pull force. The standard speed range for this 32 mm bore is 30-800 mm/s, operating between 0.15 and 1.0 MPa.
A rear screw mechanically stops the piston to shorten the 100 mm nominal stroke by up to 30 mm, creating a 70-100 mm travel window. It functions as an end-position stop and does not hold the load without air pressure.
