About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-20
The AirTAC SAIJ100X900-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the retract end position without swapping out the unit. Based on a 900 mm nominal stroke and a 20 mm adjustment code, it provides an 880-900 mm usable travel window for precise machine setup. This bore size delivers substantial thrust, pushing 5497 N at 0.7 MPa and pulling 3681 N at 0.5 MPa.
This SKU is configured with an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE electronic switches if a magnet is added later. It operates at speeds from 30-800 mm/s and relies on adjustable air cushions at both ends to decelerate the heavy 25 mm rod smoothly.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-20 Is Used
Variable End-Stop Positioning
Dials in the exact 880-900 mm retract position during machine commissioning, eliminating the need to fabricate and install external mechanical stopper blocks.
Product Size Changeover
Enables rapid line adjustments for different product lengths, using the 20 mm rear screw to accommodate varying material dimensions without changing the cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-20 the Right Cylinder?
The 20 mm rear adjuster is ideal for product changeovers, allowing you to dial in the exact 880-900 mm end-stop on the fly instead of machining external stopper blocks. Because the nominal stroke is 900 mm, an external guide is strongly recommended to prevent excessive side-loading on the extended rod.
For an exact ISO 15552 replacement, match the 100 mm bore, 900 mm stroke, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ100AX900-20 FAQ
At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating an 880-900 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
