About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-20S
The AirTAC SAIJ100X60-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers robust thrust, pushing 3927N and pulling 3681N at 0.5 MPa, while providing a usable travel window of 40 to 60 mm. The integrated SUS304 stainless steel rod offers superior corrosion resistance for demanding environments.
Equipped with a magnet for position sensing, this model supports AirTAC CMSE reed and DMSE electronic solid-state switches housed within the dual-side sensor grooves. The rear stopper screw allows you to dial in the exact retract end position during commissioning without adding external stops. It utilizes a PT G1/2 port and adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-20S Is Used
Variable End-Stop Tuning
Fine-tune the retraction point within a 40-60 mm window during machine commissioning to achieve perfect positioning without machining new hard stops.
Product Size Changeover
Quickly adjust the stroke length by up to 20 mm on packaging lines when switching between different product sizes, minimizing downtime.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod for precise clamping or pressing tasks in environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX60-20S the Right Cylinder?
Choose this 100mm bore when a smaller 80mm cylinder lacks force, as the 80mm yields 2513N push at 0.5 MPa compared to this model's 3927N. The 20mm adjustment range is ideal for product changeovers on a line, allowing you to shift the end stop dynamically rather than swapping to a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock or the AirTAC SAIL lock variant.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100mm bore, 60mm nominal stroke, 20mm adjustment, PT G1/2 port, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The 25mm rod and M20x1.5 thread provide high side-load resilience, though any application approaching the 30-800 mm/s speed range should still use an external guide.
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 SAIJ100BX60-20S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides a push force of 3927N and a pull force of 3681N. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw allows you to shorten the 60mm nominal stroke by up to 20mm, creating a usable travel window of 40 to 60mm. This stopper sets the end position but does not lock the load without continuous air pressure.
