About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-100
The AirTAC SAIJ32X105-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 105 mm travel by up to 100 mm. This creates a highly versatile 5 to 105 mm usable window, perfect for dialing in exact end positions during commissioning without swapping hardware. It features a SUS304 stainless steel rod and PT tapered ports.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit utilizes adjustable air cushions at both ends to manage deceleration. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure. For load-holding requirements, an external rod lock or a SAIL cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-100 Is Used
Changeover Calibration
Dial in the exact retract distance from 5 to 105 mm during machine format changes without installing external physical stops.
End-Position Trimming
Fine-tune the final retract position during commissioning to achieve precise alignment without machining new mounting plates.
Variable Product Stops
Adjust the stroke window on the fly to accommodate varying product lengths on a single conveyor line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-100 the Right Cylinder?
Choose this 32 mm bore when you need precise retract-position tuning within a 5-105 mm window, stepping down from a 40 mm bore that yields 628 N at 0.5 MPa if your application requires less force. The adjustable stroke is ideal for product changeovers on a line, replacing fixed-stroke SAI cylinders when external stops are impractical. Because the stroke is 105 mm, side-load risks are minimal, but always ensure the SUS304 rod is guided for optimal seal life.
When matching an ISO 15552 replacement, verify the 32 mm bore, 105 mm nominal stroke, 100 mm adjustment range, PT port threads, and the absence of a magnet (non-S). Note that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ32BX105-100 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 effective travel by up to 100 mm from the 105 mm nominal stroke, creating a usable 5 to 105 mm window. It functions as a mechanical stop and does not lock the load without air pressure.
