About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-10
The AirTAC SAIJ80X210-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and features a 200-210mm usable travel window, letting you dial in the exact end position during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model features a 25mm carbon steel rod with an M20x1.5 thread, paired with a PT tapered G3/8 port for reliable pneumatic flow. The rear adjuster acts purely as a mechanical stop to fine-tune the retract distance without needing external stops. It supports standard variable air cushions at both ends and operates at speeds between 30-800mm/s.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-10 Is Used
Precision End-Stop Tuning
Dial in the exact 200-210mm retract position during machine commissioning to achieve perfect part seating without adding external mechanical stops.
Product Changeover
Quickly adjust the stroke window by up to 10mm on packaging lines when switching between slightly different product sizes or formats.
High-Force Clamping
Leverage the 2513N push force at 0.5 MPa to securely clamp workpieces, using the fine adjustment to prevent over-travel and material damage.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-10 the Right Cylinder?
Choose this 80mm bore when you need higher thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but want to avoid the bulk of a 100mm unit. The 10mm adjustment window is ideal for applications requiring precise end-position tuning during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. For an exact ISO 15552 replacement match, verify the 210mm stroke, 10mm adjust code, G3/8 PT port, and your required mounting style.
Because the nominal stroke is 210mm, ensure adequate external guiding if the load is heavy or unsupported. Remember that the rear adjuster is a travel stop, not a locking device; this cylinder will not hold a load without live air pressure. For true load-holding requirements, consider an external rod lock or the AirTAC SAIL series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ80X210-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 10mm, providing a usable travel window of 200-210mm. It only sets the end position and does not lock the load without continuous air pressure.
