About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-10S
The AirTAC SAIJ80X175-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a built-in magnet (-S) for position sensing and a carbon steel piston rod. By turning the rear adjustment screw, you can trim the nominal 175 mm stroke back by up to 10 mm, creating a precise 165-175 mm usable travel window for fine end-position tuning without adding external stops.
This 80 mm bore generates 2513 N of pull force and 3518 N of push force at 0.5 MPa, making it robust for heavy handling. It uses PT tapered ports (G3/8), includes variable air cushions at both ends, and operates at speeds of 30-800 mm/s. The extruded aluminum barrel provides sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-10S Is Used
End-Position Tuning
Dial in the exact 165-175 mm travel during machine commissioning to perfect part seating or clamping depth without swapping hardware.
Product Changeover
Quickly adjust the rear stop on automated lines when switching to a slightly different product size, minimizing downtime.
Sensor Equipped Setup
Leverage the -S magnet and dual sensor grooves to mount CMSE or DMSE switches for precise position feedback alongside the mechanical stop.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X175-10S the Right Cylinder?
Select this 80 mm bore when your application requires higher force than a 63 mm cylinder (which offers 1402 N pull at 0.5 MPa) but does not warrant the size of a 100 mm unit. The adjustable stroke is ideal for machine setups requiring exact physical endpoints during commissioning or product changeover, functioning as a travel stop rather than a load lock. For applications needing true position holding without live air pressure, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.
When replacing an ISO 15552 cylinder, verify the 80 mm bore, 175 mm stroke, 10 mm adjustment range, PT port thread, and the required -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. Since the 175 mm stroke is moderate, ensure your rod thread (M20x1.5) and external guiding handle any side loads effectively.
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 SAIJ80X175-10S FAQ
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 10 mm. This provides a usable travel window of 165-175 mm, letting you fine-tune the end position at commissioning without changing the cylinder.
At 0.5 MPa, it provides 2513 N of pull force and 3518 N of push force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
