About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-10
The AirTAC SAIJ32X85-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a nominal 85 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 75-85 mm. This bore size delivers 402 N of push force and 345 N of pull force at 0.5 MPa, fitting compact automation tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. It uses PT tapered port threads and lacks a piston magnet, meaning it is not compatible with CMSE or DMSE sensors without modification. The rear adjuster functions strictly as a mechanical stop to dial in the retract position during commissioning; it is not a locking device and cannot hold a load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-10 Is Used
Stroke Calibration
Dial in the exact 75-85 mm travel window during machine commissioning to perfect end-position accuracy without swapping hardware.
Product Changeover
Quickly adjust the retract stop by up to 10 mm to accommodate slight variations in product size on a packaging line.
Compact Positioning
Utilize the 402 N push force and ISO 15552 footprint for precise, compact assembly tasks requiring fine-tuned travel limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-10 the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa, stepping down from a 40 mm bore that yields 628 N if space is tight, or up if you need more thrust. An adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops to accommodate product changeovers or precise setup tuning without adding external stops. For load-holding without live air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster only limits travel. When replacing an ISO 15552 cylinder, match the 32 mm bore, 85 mm stroke, 10 mm adjustment, PT port, and lack of a magnet. Given the 85 mm stroke is under 300 mm, external side-load guides are less critical, but the 12 mm rod and M10x1.25 thread still handle moderate side loads effectively.
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 SAIJ32AX85-10 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 82 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 85 mm nominal stroke by up to 10 mm, creating a 75-85 mm usable travel window. It only sets the end position and does not lock or hold the load without air pressure.
