About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-10S
The AirTAC SAIJ80X220-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 220 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 210 to 220 mm. At 0.5 MPa operating pressure, it delivers 2513 N of push force and 2268 N of pull force, making it suitable for heavy-duty positioning tasks.
This variant includes a standard magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel integrates sensor grooves on both sides, and the carbon steel rod features an M20x1.5 thread. The rear adjustment screw acts purely as a mechanical stop to fine-tune the end position without adding external stops; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-10S Is Used
Machine Setup Tuning
Dial in the exact 210-220 mm end-stop during initial commissioning to perfect part ejection without machining external spacers.
Product Changeover
Quickly adjust the stroke by up to 10 mm to accommodate slightly different package sizes on a packaging line.
Heavy Load Positioning
Leverage the 2513 N push force to move heavy pallets or assemblies into a precise final location.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-10S the Right Cylinder?
Choose this 80 mm bore when you need more force than a 63 mm cylinder (1559 N push at 0.5 MPa) but want to avoid the larger footprint of a 100 mm bore (3927 N). The 10 mm rear adjuster is ideal for final end-position tuning during machine commissioning or product changeover, saving the downtime of physically swapping a fixed-stroke SAI cylinder. Because the 220 mm stroke exceeds 300 mm is false here, but for any stroke over 300 mm, you should guide long unsupported rods to prevent side-loading damage.
To match this ISO 15552 interchangeable cylinder, specify the 80 mm bore, 220 mm stroke, 10 mm adjustment, PT tapered G3/8 port, and the -S magnet. The SAIJ mounting set omits FB, CA, CB, and CR brackets, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. For load-holding without live air, select an SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a travel stop.
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 SAIJ80X220-10S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 5026 N of push force.
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm, creating a 210-220 mm usable window. It acts as a mechanical stop for end-position tuning and is not a lock; it will not hold the load without continuous air pressure.
