About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-10S
The AirTAC SAIJ80X105-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 2513N push force at 0.5 MPa and operates at speeds between 30-800 mm/s. Equipped with a PT tapered port and a SUS304 stainless steel rod, it is built for demanding environments.
This specific SKU allows you to trim the effective travel back by up to 10 mm, creating a 95-105 mm usable stroke window for fine end-position tuning during commissioning. The extruded aluminum barrel includes dual sensor grooves, and the integrated -S magnet works seamlessly with AirTAC CMSE (reed) and DMSE (electronic) switches.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-10S Is Used
Machine Setup & Changeover
Dial in the 95-105 mm stroke window during commissioning to hit exact end positions without adding external stops or swapping cylinders.
Variable End Stops
Fine-tune the retract position on the fly to accommodate minor product size variations on the production line.
Corrosive Assembly Lines
The SUS304 stainless steel rod and PT ports make this adjustable cylinder suitable for manufacturing environments requiring high corrosion resistance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-10S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982N push at 0.5 MPa) lacks the necessary thrust but a 100 mm bore (3927N) is oversized. The adjustable stroke is ideal for applications requiring variable end stops or product changeovers without swapping the cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a lock. If your application requires load-holding without live air pressure, consider the SAIL or BSAI series instead. This cylinder is dimensionally interchangeable with other ISO 15552 profile cylinders.
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 SAIJ80 Adjustable Cylinder SAIJ80BX105-10S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513N and a pull force of 2268N. It can reach a maximum push force of 4523N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 105 mm stroke by up to 10 mm, providing a usable travel window of 95-105 mm. It acts as a mechanical stop for end-position tuning and is not a lock.
