About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-100S
The AirTAC SAIJ80X195-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a broad usable travel window of 95-195 mm, allowing you to dial back the nominal 195 mm stroke by up to 100 mm. Delivering a robust 3518 N push force at 0.7 MPa, it is built to handle demanding actuation tasks.
This unit includes a standard carbon steel piston rod and a PT tapered port thread. The -S option equips it with a magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear stopper mechanism acts solely as a travel end-point tuner for commissioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-100S Is Used
Product Changeovers
Quickly reconfigure the 95-195 mm travel window for different carton sizes on a packaging line without changing hardware.
End-Position Tuning
Dial in the exact retract distance during machine commissioning to perfect a pressing or clamping operation.
Variable Stops
Use the 100 mm adjuster screw as a built-in mechanical stop to create multiple stroke endpoints for automated assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-100S the Right Cylinder?
Selecting this 80 mm bore over a 63 mm variant (which yields 2182 N push at 0.7 MPa) gives you significantly higher thrust for heavier payloads. The 100 mm adjustment range is ideal for machines running multiple product sizes, as you can fine-tune the retract end-position without swapping the cylinder or adding external stops. For load-holding requirements without live air, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
To match this ISO 15552 replacement exactly, specify: 80 mm bore, 195 mm stroke, 100 mm adjustment, PT G3/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet. With a 195 mm stroke, side loads are minimal, but ensure the 25 mm rod and M20x1.5 thread are properly aligned to prevent binding.
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 SAIJ80X195-100S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder provides 3518 N of push force and 2268 N of pull force. It can reach a maximum push force of 4523 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke from 195 mm down to as little as 95 mm. This creates a 100 mm tuning window to set the exact retract position during setup, though it functions as a stop and does not lock the load without air pressure.
