About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10S
The AirTAC SAIJ100X40-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5MPa. It features a carbon steel piston rod and a PT tapered port thread. Because this SKU includes a magnet, it supports position detection using AirTAC CMSE reed or DMSE electronic solid-state switches housed in the dual-side sensor grooves.
With a nominal 40mm stroke and a 10mm adjustment range, the usable travel window is 30-40mm. This allows you to dial in the exact end position during commissioning without adding external stops. The rear screw acts purely as a travel stop for deceleration alongside the standard air cushions; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10S Is Used
Short-Stroke Pressing
Dial in the exact 30-40mm contact point for pressing bearings without swapping physical spacers.
Clamp Position Tuning
Fine-tune the retract end-stop during machine commissioning to accommodate varying part tolerances.
Product Changeover
Quickly adjust the stroke end by up to 10mm when switching the production line to a new product size.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10S the Right Cylinder?
Choose this 100mm bore when you need heavy thrust (3927N push at 0.5MPa) in a compact 40mm travel, stepping up from a 63mm bore that only offers 1559N. The 10mm adjuster is ideal for fine-tuning short clamping or pressing moves. If your process requires the cylinder to hold position safely without continuous air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the stop screw.
For an exact ISO 15552 replacement match, specify a 100mm bore, 40mm nominal stroke, 10mm adjustment, PT port thread, and the -S magnet option. Mounting choices are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100 Adjustable Cylinder SAIJ100X40-10S FAQ
At 0.5MPa it provides 3927N of push force and 3681N of pull force. At 0.7MPa the push force increases to 5497N.
The rear adjuster screw lets you trim the effective travel back by up to 10mm, creating a 30-40mm usable stroke window. It functions as an end-stop, not a lock.
