About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-100
The AirTAC SAIJ32X950-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down by up to 100 mm, creating an 850-950 mm usable window. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, scaling up to 724 N of push at 0.9 MPa. This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads.
Because the nominal 950 mm stroke approaches the maximum standard limit for this 32 mm bore, the integrated rear stopper is highly valuable for fine-tuning the end position without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and while no magnet is specified here, adding one enables CMSE reed or DMSE electronic solid-state sensors. The adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-100 Is Used
Machine Setup Tuning
Dial in the exact 850-950 mm end position during initial commissioning without swapping cylinders or fabricating external stopper blocks.
Product Changeover
Quickly adapt the stroke window on a packaging line when product sizes change, using the rear adjuster to shorten the travel by up to 100 mm.
Extended Travel Assembly
Leverage the 950 mm stroke for long-reach clamping or positioning tasks while retaining the ability to fine-tune the retract distance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-100 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa; if you need less force, dropping to a smaller bore is ideal, while stepping up to a 40 mm bore yields 628 N. An adjustable-stroke cylinder is selected over a fixed SAI model when you need on-the-fly end-position tuning during commissioning or product changeovers.
For a drop-in ISO 15552 replacement, match the 32 mm bore, 950 mm nominal stroke, 100 mm adjustment, PT port thread, SUS304 (B) rod material, and standard mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Since the stroke is 950 mm, the 12 mm rod requires external guidance to prevent excessive side-loading and buckling. Note that the rear adjuster is a stop, not a lock; for load-holding without live air, use an SAIL or BSAI cylinder.
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 SAIJ32BX950-100 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N. The operational speed range is 30-800 mm/s.
The rear adjuster screw allows you to shorten the nominal 950 mm stroke by up to 100 mm, resulting in a usable travel window of 850-950 mm. This stopper sets the travel end but does not lock or hold the load without continuous air pressure.
