About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-10S
The AirTAC SAIJ32X85-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 85 mm stroke by up to 10 mm. This yields a precise 75-85 mm usable travel window, enabling exact end-position tuning at commissioning without swapping out the unit. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks perfectly.
Built with a SUS420J2 stainless steel rod and PT tapered ports, this variant includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 footprints, omitting FB and rear pivot options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-10S Is Used
End-Stop Calibration
Fine-tune the 75-85 mm travel window during machine commissioning to perfect the retract position without adding external stopper blocks.
Product Changeover
Quickly adapt the cylinder's effective stroke on automated lines when switching to a slightly shorter product variant.
Light-Duty Positioning
Leverage the 402 N push force at 0.5 MPa for precise handling of smaller components in assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-10S the Right Cylinder?
Choose this 32 mm bore when a 40 mm bore's 628 N at 0.5 MPa would be excessive for your payload, but you need more precision than smaller compact cylinders offer. The 10 mm adjustment range is ideal for product changeovers where the exact retract position shifts slightly, saving you from machining external stops. To match an ISO 15552 replacement, verify the 32 mm bore, 85 mm stroke, 10 mm adjuster, PT ports, and the -S magnet requirement.
Because the stroke is under 300 mm, the 12 mm rod handles standard side loads adequately, though long unsupported loads still need an external guide. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true drop protection, consider an external rod lock or pilot-operated check valve.
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 SAIJ32AX85-10S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 85 mm stroke by up to 10 mm, creating a 75-85 mm travel window. This stopper only sets the end position; it does not lock the load without continuous air pressure.
