About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X155-10S
The AirTAC SAIJ80X155-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa, placing it firmly in the heavy-duty class for industrial automation. By turning the built-in adjustment screw, you can trim the nominal 155 mm travel back by up to 10 mm, creating a precise 145-155 mm usable stroke window without needing external stops. The -S suffix indicates an integrated magnet for position sensing, designed to work seamlessly with AirTAC CMSE reed and DMSE electronic switches mounted into the dual-side sensor grooves on the extruded aluminum barrel.
This model features a 25 mm carbon steel piston rod with an M20x1.5 thread, providing high rigidity and excellent resistance to bending under heavy loads. Pneumatic flow is managed through PT tapered G3/8 ports, while variable air cushions at both ends allow you to regulate end-of-stroke deceleration. Remember that the rear adjuster and cushions act as travel stops and shock absorbers, not as locking devices; the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X155-10S Is Used
Machine Commissioning
Dial in the exact 145-155 mm retract position during setup to align heavy clamping fixtures without machining custom spacer plates.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when switching to a slightly shorter product format.
Heavy Forming Stops
Leverage the 2513N push force at 0.5 MPa for pressing operations while fine-tuning the bottoming position to prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X155-10S the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (which provides 1559N push at 0.5 MPa) but does not warrant the size and air consumption of a 100 mm unit (3927N). The 10 mm adjustable range is ideal for fine-tuning the retract end position during machine commissioning or product changeovers, allowing you to dial in the exact 145-155 mm travel without swapping out the cylinder or fabricating external stopper blocks. For fixed-position tasks that never require end-position adjustment, the standard AirTAC SAI cylinder is a simpler alternative.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 155 mm stroke, PT G3/8 port thread, and the -S magnet requirement. The SAIJ series supports a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR brackets. If your process demands true load-holding without continuous air pressure, consider the AirTAC SAIL or BSAI clamp-lock cylinders instead. Although the 25 mm rod handles side loads well, always use an external guide rail for any heavy or off-center loads.

- ✓ 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 SAIJ80X155-10S FAQ
It features a rear mechanical screw that acts as a stopper, allowing you to shorten the effective travel from 155 mm down to a minimum of 145 mm. This provides a 10 mm adjustable window for precise end-position tuning at commissioning.
At a 0.5 MPa operating pressure, the SAIJ80X155-10-S provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf of push force.
