About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20S
The AirTAC SAIJ100X60-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 40-60 mm usable travel window, letting you trim the 60 mm nominal stroke by up to 20 mm during machine commissioning. Delivering 3927 N of push force at 0.5 MPa, this carbon-steel rod unit handles heavy loads with precision.
This model includes a magnet for CMSE and DMSE sensors, utilizing reed and solid-state electronic switches for exact position feedback. The extruded aluminum barrel omits tie-rods, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. The rear screw acts purely as a mechanical stop for deceleration, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20S Is Used
Press Fit Tuning
Dial in the exact 40-60 mm insertion depth for delicate bearing press fits without repositioning the cylinder body.
Product Changeover
Quickly adjust the end-stop up to 20 mm during packaging line format changes to accommodate varying container heights.
Heavy Clamping
Secure heavy workpieces with 3927 N of force while fine-tuning the clamping position to avoid material deformation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20S the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust, such as 3927 N push at 0.5 MPa, but want on-the-fly end-position tuning without swapping components. If your application requires less force, stepping down to an 80 mm bore yields 2513 N. The -20 mm adjustment code is ideal for product changeovers where the exact end-stop varies by a few millimeters. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 60 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet requirement. The 25 mm rod and M20x1.5 thread provide excellent rigidity, though even with a short 60 mm stroke, external guides are recommended for heavy lateral loads.
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 SAIJ100X60-20S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 801 kgf of push force.
The rear adjuster screw lets you mechanically shorten the 60 mm stroke by up to 20 mm, creating a 40-60 mm usable travel window. This allows precise end-position tuning during setup without needing external stops.
