About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-100S
The AirTAC SAIJ80X230-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 25 mm rod with an M20x1.5 thread and delivers 2513 N of pull force at 0.5 MPa. With its built-in magnet, this unit is fully compatible with CMSE reed and DMSE electronic solid-state sensors mounted along the dual-side extruded barrel grooves.
This SKU provides a 130 to 230 mm usable travel window, allowing you to dial back the nominal 230 mm stroke by up to 100 mm. The rear stopper screw lets you fine-tune the end position during commissioning or product changeover without swapping the cylinder or adding external stops. The adjuster acts solely as a travel stop and works alongside the variable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-100S Is Used
Machine Changeover
Quickly dial in the 130-230 mm travel window during product size transitions on a packaging line without physically swapping out the actuator.
Variable End-Stops
Set precise retract positions for multi-format tooling, using the 100 mm adjustment range to accommodate different part depths on the fly.
Assembly Line Tuning
Fine-tune the end-of-stroke position during initial commissioning to perfect pressing or clamping forces without machining new hard stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-100S the Right Cylinder?
Choose this 80 mm bore when you need higher force than the 63 mm class (which offers 1402 N pull at 0.5 MPa) but want to avoid the larger footprint of the 100 mm option. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops or frequent product-size changeovers. Keep in mind the rear adjuster is not a lock; it cannot hold a load without live air, so for fail-safe holding you should look at the SAIL or BSAI series.
This SAIJ80X230-100-S is dimensionally interchangeable per ISO 15552 and uses a PT tapered G3/8 port. It supports the reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 230 mm stroke is relatively long, the 25 mm rod carries side loads well, but an external guide is still recommended for unsupported loads to prevent premature wear.
Quick checklist

- ✓ 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 SAIJ80X230-100S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of pull force and 3518 N of push force. It can reach a maximum push force of 4523 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from its 230 mm nominal stroke down to as little as 130 mm, giving you a 100 mm tuning window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
