About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-20
The AirTAC SAIJ100X60-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the nominal 60 mm travel to a precise 40-60 mm window during commissioning. Built with an extruded aluminum barrel, it delivers 3927 N of push force at 0.5 MPa and uses a G1/2 port. This configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads.
Because the rear screw acts purely as a travel stop and relies on the air cushion for end-of-stroke deceleration, it cannot hold a load without live air pressure. For load-holding without continuous pressure, you would need an external rod lock or a related type like the SAIL or BSAI. The standard SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-20 Is Used
Precision End-Stop Tuning
Fine-tune the clamping end position within the 40-60 mm window during initial machine commissioning to achieve exact material contact without adding external stops.
Rapid Product Changeover
Quickly adjust the retract distance on a packaging line to handle different product sizes, using the rear screw to set the new travel limit in seconds.
High-Force Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures into place, relying on the adjuster to set the exact resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-20 the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder (providing 2513 N push at 0.5 MPa) lacks the thrust for your setup. The SAIJ100X60-20 is selected over a fixed-stroke SAI when a machine requires variable end-stops to accommodate product changeovers without physically swapping cylinders. To match this ISO 15552 replacement exactly, specify a 100 mm bore, 60 mm stroke, 20 mm adjustment, PT port thread, SUS304 rod, and no magnet.
With a 60 mm stroke, the side-load risk is minimal, but always ensure the M20x1.5 rod thread is properly aligned. Since this unit lacks a magnet, position sensing requires external mechanical switches rather than AirTAC CMSE or DMSE sensors.
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 SAIJ100BX60-20 FAQ
At 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 allows you to shorten the 60 mm nominal stroke by up to 20 mm, creating a usable travel window of 40 to 60 mm. It functions as a mechanical stop to set the exact end position, but it does not lock the load without live air pressure.
