About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-30S
The AirTAC SAIJ32X105-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 105 mm stroke that can be dialed back by up to 30 mm, creating a precise 75-105 mm usable travel window for exact end-position tuning during commissioning. Delivering 402 N of push force at 0.5 MPa, it integrates a magnetic piston for position sensing.
This 32 mm bore unit features a 12 mm carbon steel rod and M10x1.25 threading. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE solid-state switches. It utilizes a PT tapered port (G1/8) and offers adjustable air cushions at both ends to decelerate the 30-800 mm/s travel speeds smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-30S Is Used
Machine Setup & Commissioning
Fine-tune the 75-105 mm retract end-stop during initial machine build to dial in exact clamping distances without machining custom spacers.
Product Size Changeovers
Quickly adjust the effective stroke by up to 30 mm on packaging lines when switching between slightly different product lengths or widths.
Variable End-Stop Positioning
Use the rear mechanical stop to set precise lower travel limits for light-duty assembly presses where 402 N of push force is sufficient.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-30S the Right Cylinder?
Choose this adjustable-stroke model when a fixed 105 mm SAI cylinder cannot provide the exact end-stop required without adding external shims. The 32 mm bore yields 402 N push and 345 N pull at 0.5 MPa; stepping up to a 40 mm bore increases push force to 628 N, while dropping to a smaller bore reduces output. The rear adjuster acts solely as a mechanical stop to trim the retract position and does not hold the load without live air—use SAIL or BSAI cylinders for fail-safe locking. For this 105 mm stroke, side loads are minimal, but external guides remain recommended for rigid loads.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 32 mm bore, 105 mm stroke, 30 mm adjustment range, PT G1/8 port, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32X105-30S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the 105 mm nominal stroke by up to 30 mm, providing a usable travel window of 75-105 mm. It sets the end position but does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
