About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40S
The AirTAC SAIJ32X210-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 170 to 210 mm, allowing you to dial back the nominal 210 mm stroke by up to 40 mm during commissioning. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE or DMSE sensors. It features PT tapered port threads (G1/8) and variable air cushions at both ends. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40S Is Used
Machine Changeover
Dial in the 170-210 mm travel window on the fly to accommodate new product lengths without replacing the cylinder.
End-Position Tuning
Use the rear stopper to precisely set the retract end-point during initial commissioning, avoiding external shims.
Light Force Positioning
Leverage the 402 N push force at 0.5 MPa for accurate low-force positioning tasks on automated lines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40S the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, avoiding the need to physically swap a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ cannot hold a load without live air, so for fail-safe load holding consider a SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 cylinder, match it by its 32 mm bore, 210 mm stroke, 40 mm adjustment, PT G1/8 ports, and -S magnet.
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 SAIJ32BX210-40S 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 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the effective travel from the 210 mm nominal stroke down by up to 40 mm, creating a 170 to 210 mm usable window. It acts as a mechanical stop to fine-tune the end position without changing the cylinder.
