About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-40
The AirTAC SAIJ100X60-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 3927N of push force at 0.5MPa and provides a usable travel window of 20-60mm, letting you trim the 60mm nominal stroke by up to 40mm during machine commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The rear adjustment screw acts purely as a travel stop to fine-tune the retract end position without adding external stops. It supports a speed range of 30-800mm/s and uses the standard SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-40 Is Used
End-Stop Tuning
Dial in the exact retract position during machine setup by adjusting the rear screw up to 40mm without replacing the cylinder.
Product Changeovers
Quickly adapt the 20-60mm travel window to accommodate varying product sizes on a single production line.
Clamp Positioning
Set precise clamping locations for different workpiece heights using the integrated rear stopper mechanism.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-40 the Right Cylinder?
Choose this 100mm bore when an 80mm bore (yielding 2513N at 0.5MPa) is insufficient, but a 125mm bore (6136N at 0.5MPa) would be overkill. The adjustable stroke is ideal for product changeovers where exact end-of-stroke positioning varies slightly, saving you from swapping out a fixed-stroke SAI cylinder. Remember that the rear adjuster only sets the travel end and does not hold the load without live air; for true load-holding without pressure, consider an SAIL or BSAI cylinder.
For an ISO 15552 replacement, match the 100mm bore, 60mm stroke, 40mm adjustment, PT port, and your required mounting hardware. Because the stroke is under 300mm, side-load stress is minimal, but long unsupported strokes still require an external guide to prevent rod binding.
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 SAIJ100BX60-40 FAQ
At a 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can reach up to 7068N push force at 0.9MPa.
The rear adjuster screw lets you mechanically shorten the 60mm nominal stroke by up to 40mm, providing a usable travel window of 20-60mm. This allows fine-tuning of the end position at commissioning without adding external stops.
