About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-10S
The AirTAC SAIJ80X35-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. With a 35 mm nominal stroke and a 10 mm adjustment range, it provides a usable travel window of 25-35 mm without requiring external stops. It delivers a robust 2513 N push force at 0.5 MPa, making it ideal for high-force operations in tight spaces.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, while the PT tapered port threads ensure a secure pneumatic connection.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-10S Is Used
Short-Stroke Clamping
Provides 2513 N of clamping force at 0.5 MPa with a tunable 25-35 mm travel window for securing variable part thicknesses.
Commissioning Calibration
Allows operators to dial in the exact retract end-position by up to 10 mm during setup, avoiding the need to add external shims.
Product Changeover
Speeds up production line changeovers by letting technicians quickly adjust the stroke end-stop to match new product dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-10S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial force, such as 2513 N push at 0.5 MPa, within a very short stroke. If your force requirements are lower, stepping down to a 63 mm bore yields 1559 N; stepping up to a 100 mm bore provides 3927 N. The adjustable stroke is perfect for machine setups requiring precise end-stop tuning without swapping components.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 35 mm stroke, 10 mm adjustment, PT port thread, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80AX35-10S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 25-35 mm from the 35 mm nominal stroke, letting you fine-tune the retract position without changing the cylinder.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
