About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-100S
The AirTAC SAIJ32X105-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 105 mm stroke with an impressive usable travel window of 5 to 105 mm, allowing you to dial back the extension by up to 100 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, utilizing a G1/8 port and a 12 mm carbon steel rod with M10x1.25 threading.
Because the adjuster acts purely as a mechanical stop at the retract end, it does not hold the load without live air pressure. This extruded aluminum barrel includes a magnet for position sensing, seamlessly supporting AirTAC CMSE reed and DMSE electronic switches via the dual-side sensor grooves. The mounting interface covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-100S Is Used
Variable End-Stop Tuning
Perfect for test fixtures where the extension length must be dialed in precisely across a 5 to 105 mm window without adding external physical stops.
Machine Changeover
Quickly adapt a packaging line to new product sizes by turning the rear adjuster, trimming the stroke back as needed rather than re-mounting hardware.
Light-Duty Positioning
Ideal for pushing light components into a workstation, using the 402 N thrust at 0.5 MPa and the fine-tune capability to prevent overtravel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-100S the Right Cylinder?
Select this model when a machine setup requires extensive end-position tuning or product changeovers without physically swapping out the cylinder. The 100 mm adjustment range on a 105 mm stroke provides extreme flexibility, functioning almost like a variable stop. If your application needs higher force, stepping up to a 40 mm bore raises the 0.5 MPa push force to 628 N. Conversely, if you need to hold a load statically without continuous air pressure, the SAIJ adjuster will not act as a lock; you should look at the SAIL or BSAI series instead.
For replacing an ISO 15552 cylinder, match the 32 mm bore, 105 mm nominal stroke, 100 mm adjustment range, PT tapered port threads, and the -S magnet. As with all pneumatic setups, ensure your filtered air supply operates within the 0.15 to 1.0 MPa pressure range and 30 to 800 mm/s speed limits.
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 SAIJ32X105-100S FAQ
It features a rear external stopper that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window from 5 to 105 mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
