About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-10
The AirTAC SAIJ100X90-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel from 90 mm down to 80 mm. This 10 mm adjustment window is ideal for fine-tuning end positions at commissioning without swapping out the entire actuator. It delivers a robust 3927 N of push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
Equipped with a 25 mm carbon steel piston rod and an M20x1.5 rod thread, this bore size handles high side loads far better than smaller variants. The extruded aluminum barrel includes sensor grooves on both sides for mounting AirTAC CMSE reed or DMSE electronic switches, though this specific SKU is supplied without a magnet. It supports a reduced set of ISO 15552 mountings—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-10 Is Used
Machine Setup Tuning
Dial in the exact 80-90 mm end position during initial commissioning to perfect a pressing operation without machining external stop blocks.
Product Changeover
Quickly shorten the stroke by up to 10 mm on a packaging line when switching to a slightly smaller carton size, minimizing downtime.
Heavy Fixture Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy industrial jigs into place, using the adjuster to set the final resting point precisely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-10 the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust—stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, which may be insufficient for heavier fixtures. The adjustable stroke is selected over a fixed SAI cylinder when a process requires exact end-stop tuning during machine setup or product changeover. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series. To match this ISO 15552 replacement, verify the 90 mm stroke, 10 mm adjustment, G1/2 (PT tapered) port, and mounting style.
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 SAIJ100X90-10 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push force at 0.9 MPa.
The rear adjuster screw allows you to mechanically shorten the nominal 90 mm stroke by up to 10 mm, providing a usable travel window of 80-90 mm. The adjuster acts as a stop and does not function as a lock or brake.
