About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X25-10S
The AirTAC SAIJ100X25-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 15 to 25 mm for precise end-position tuning. It features a carbon steel rod and PT tapered port threads. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads within a compact footprint. The integrated magnet (-S) supports position sensing using AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves.
This adjustable stopper allows you to dial in the exact end-of-stroke position during commissioning without adding external stops or swapping the cylinder. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X25-10S Is Used
Short-Stroke Pressing
Ideal for high-force pressing operations where the 15-25 mm adjustable travel window allows operators to dial in the exact material compression depth.
Machine Changeover
Speeds up product line changeovers by letting technicians quickly adjust the cylinder's end-stop position without physically swapping out the actuator.
Heavy-Duty Clamping
Provides robust 3927 N clamping force at 0.5 MPa for holding large workpieces, with the rear screw allowing precise clamping pressure tuning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X25-10S the Right Cylinder?
Select this 100 mm bore when a 63 mm bore (1559 N push at 0.5 MPa) is insufficient for your heavy-duty clamping or pressing task, but a 125 mm unit would be physically oversized. The 10 mm adjustment range is ideal for fine-tuning short 25 mm movements, offering flexibility over a fixed-stroke SAI cylinder when exact end-positioning is critical. Because the stroke is only 25 mm, side-loading is minimal, though the robust 25 mm rod and M20x1.5 thread handle high axial stress well.
For load-holding without continuous air pressure, note that the rear adjuster is a stop, not a lock; you must use an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI cylinders. To replace an ISO 15552 unit, match the 100 mm bore, 25 mm stroke, 10 mm adjustment, G3/8 PT ports, and the -S magnet requirement.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100X25-10S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you mechanically shorten the 25 mm nominal stroke by up to 10 mm, creating a 15-25 mm usable travel window. It acts as a physical stop to fine-tune the end position and is not a locking mechanism.
