About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-40S
The AirTAC SAIJ80X100-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa, utilizing a 25mm carbon steel rod with an M20x1.5 thread. The built-in magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches. By turning the external rear screw, you can shorten the effective travel, creating a usable window of 60-100mm for precise end-position tuning.
This adjustable-stroke design eliminates the need to swap cylinders during product changeovers or commissioning. It features variable air cushions at both ends and a G3/8 PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides. The rear stopper acts only as a travel limit and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-40S Is Used
Product Changeover Dials
Quickly adjust the end stop from 60 to 100mm when switching production lines to different package lengths, avoiding physical cylinder swaps.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to achieve exact clamping or pressing positions without adding external stopper blocks.
Variable Stroke Forming
Set precise forming depths on the fly for varying material thicknesses, leveraging the 2513N push force at 0.5MPa to execute consistent work.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-40S the Right Cylinder?
Choose this 80mm bore when your application requires substantial force but demands on-the-fly stroke trimming. If you need less thrust, stepping down to the 63mm bore yields 1559N push at 0.5MPa. The 40mm adjustment range is ideal for machines processing varying product sizes, allowing you to dial in the end stop without adding external physical stops. Unlike a fixed-stroke SAI cylinder, this model provides a 60-100mm travel window for exact commissioning flexibility.
Because the 25mm rod and M20x1.5 thread handle high side loads well, it is robust for general industrial use. However, for any stroke of 300mm or more, an external guide is recommended to prevent rod deflection. This cylinder uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. It is dimensionally interchangeable per ISO 15552 standards.

- ✓ 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 SAIJ80X100-40S FAQ
At an operating pressure of 0.5MPa, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At 0.9MPa, the push force increases to 4523N.
The rear adjuster screw allows you to shorten the nominal 100mm stroke by up to 40mm, creating a usable travel window of 60 to 100mm. This stopper only sets the travel end and does not lock the load without live air pressure.
