About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-30S
The AirTAC SAIJ32X85-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 85 mm stroke that can be dialed back by up to 30 mm, creating a precise 55-85 mm usable travel window for fine-tuning end positions during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups requiring exact stopping points.
This variant features an SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid ports are PT tapered thread (G1/8). The rear screw acts purely as a mechanical stop to set the travel end and does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-30S Is Used
End-Position Tuning
Dial in the exact 55-85 mm travel distance during machine commissioning to accommodate sensor placement or varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper on the line when switching between different product sizes, reducing downtime and eliminating the need for external mechanical stops.
Compact Assembly Stops
Utilize the 32 mm bore's 402 N push force to actuate small clamps or stops in tight spaces where the exact end position must be tweaked on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-30S the Right Cylinder?
Choose this 32 mm bore when an application requires a 55-85 mm adjustable stroke and up to 402 N of thrust at 0.5 MPa. If your setup demands higher force, stepping up to the 40 mm bore provides 628 N of push force. Select the SAIJ adjustable version over a fixed SAI cylinder when you need variable end-stops for product changeovers or machine setup without adding external stops. For strokes of 300 mm or more, always use an external guide to support side loads.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 32 mm bore, 85 mm nominal stroke, 30 mm adjustment range, PT G1/8 ports, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the adjuster and air cushions only decelerate the travel; they do not hold the load. For position holding without live air, consider an external rod lock or the SAIL lock 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 SAIJ32AX85-30S 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 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 85 mm nominal stroke by up to 30 mm, providing a usable travel window of 55 to 85 mm. The adjuster acts as a mechanical stop to set the end position and does not function as a lock.
