About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-10
The AirTAC SAIJ80X105-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3518N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed and DMSE electronic switches without extra brackets.
This model provides a usable travel window of 95-105 mm, letting you dial back the nominal 105 mm stroke by up to 10 mm. The rod is constructed from SUS304 stainless steel for superior corrosion resistance, and the fluid porting uses a PT tapered thread. The rear adjuster acts strictly as a mechanical stop to fine-tune the end position at commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-10 Is Used
Machine Changeover
Fine-tune the 95-105 mm stroke during product size transitions to reposition stops without changing hardware.
Variable End-Stop Setup
Dial in the exact retraction point during commissioning using the rear adjuster screw for precise positioning.
Heavy-Duty Positioning
Leverage the 3518N push force at 0.7 MPa to move heavy pallets or fixtures while adjusting travel limits on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX105-10 the Right Cylinder?
Choose this 80 mm bore when an application requires more thrust than a 63 mm cylinder (which provides 2182N at 0.7 MPa) but does not need the full 5497N push of a 100 mm unit. The adjustable 95-105 mm travel window is ideal for machine setups requiring precise end-position tuning during commissioning or product changeover, eliminating the need to swap cylinders or bolt on external stops.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 105 mm nominal stroke, 10 mm adjustment range, PT G3/8 port, and standard mounting interface. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 105 mm, a side-load guide is not strictly required, but always ensure the SUS304 rod is properly supported in heavy lateral applications. For applications requiring true load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ80BX105-10 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 10 mm, creating a 95-105 mm usable window. It acts as a mechanical stop to fine-tune the retract position during setup, but it is not a lock and will not hold the load without live air pressure.
At a 0.7 MPa operating pressure, the 80 mm bore generates a push force of 3518N and a pull force of 2268N. It can deliver up to 4523N push at 0.9 MPa.
