About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-10
The AirTAC SAIJ80X105-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 95-105 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it provides robust actuation for mid-weight machinery. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
A 10 mm adjustment screw at the rear allows you to fine-tune the retract end position during commissioning without adding external stops. This cylinder uses a G3/8 port and a 25 mm carbon steel rod. The mounting hardware supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces, deliberately omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-10 Is Used
End-Stop Calibration
Dial in the exact 95-105 mm retract position during machine commissioning to perfect part seating without machining external stop blocks.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly different product size, minimizing downtime.
Mid-Force Actuation
Leverage the 2513 N push force at 0.5 MPa for moving heavier jigs or clamping assemblies where a 50 mm bore falls short.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-10 the Right Cylinder?
Select this 80 mm bore when a 50 mm bore yields insufficient thrust (982 N push at 0.5 MPa) but a 100 mm bore is oversized. The 10 mm rear adjuster is ideal for dialing in exact end positions during machine setup or product changeovers, replacing the need to swap a fixed-stroke SAI cylinder. If your setup requires holding a load without live air pressure, note that this adjuster acts only as a travel stop; you should instead specify an SAIL locking cylinder or an external rod lock.
For this 105 mm stroke, side loads are minimal, but the 25 mm rod and M20x1.5 thread handle standard guiding tasks well. Since no magnet is specified, position sensing via CMSE reed or DMSE electronic switches is not enabled out of the box. Operating speed ranges from 30-800 mm/s, controlled by variable air cushions at both ends.
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 SAIJ80X105-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 105 mm stroke down to 95 mm. It trims the travel end for fine-tuning but does not lock the load without live air pressure.
