About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-100S
The AirTAC SAIJ32X115-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 115 mm stroke that can be dialed back by up to 100 mm, yielding a wide 15-115 mm usable travel window for highly flexible end-position tuning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. Equipped with a SUS304 stainless steel rod, it is optimized for corrosive environments, while the integrated magnet enables position feedback via CMSE reed or DMSE electronic sensors.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during product changeovers or commissioning. The rear adjuster acts strictly as a mechanical travel stop to set deceleration limits, not as a lock to hold loads without live air. For applications requiring load-holding without continuous pressure, AirTAC SAIL or BSAI cylinders are the correct solutions. The extruded aluminum barrel includes sensor grooves on both sides, and mounting options span the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-100S Is Used
Product Changeover Tuning
Dial in the exact retract distance from 15 to 115 mm during format size changes on a packaging line, avoiding the need to physically swap out the entire actuator.
Prototyping Cell Setup
Experiment with multiple end-stop positions during machine commissioning to find the optimal operating window without adding external mechanical stops.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod and 402 N push force for precise clamping or positioning tasks in washdown or chemical-prone manufacturing areas.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-100S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires 402 N of push force at 0.5 MPa alongside extreme stroke variability. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force. The massive 100 mm adjustment range on a 115 mm nominal stroke is ideal for prototyping cells or production lines handling frequent product-size changes, allowing operators to fine-tune the retract end-stop on the fly instead of maintaining a large inventory of fixed-stroke SAI cylinders.
When sourcing an ISO 15552 interchangeable replacement, match the 32 mm bore, 115 mm stroke, 100 mm adjustment, PT tapered port threads, and the -S magnet requirement. The 12 mm carbon-steel-derived rod diameter and M10x1.25 thread handle moderate side loads, but any stroke exceeding 300 mm requires an external guide to prevent rod binding.
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 SAIJ32BX115-100S FAQ
The rear adjuster allows you to mechanically shorten the effective stroke by up to 100 mm from the 115 mm nominal length, providing a 15-115 mm usable travel window. It functions as a travel stop to set the end position and does not lock or hold the load without live air pressure.
At 0.5 MPa, the 32 mm bore generates 402 N of push force and 345 N of pull force. Because it includes a magnet (-S), it is fully compatible with AirTAC CMSE reed switches and DMSE electronic solid-state sensors mounted in the dual-side barrel grooves.
