About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-100S
The AirTAC SAIJ80X260-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel by up to 100 mm. This yields a highly versatile 160-260 mm usable stroke window, perfect for dialing in exact end-of-stroke positions during machine commissioning or product changeovers without swapping out the physical actuator.
This specific SKU is built for harsh environments, featuring a SUS304 stainless steel rod (option B) and tapered PT ports. The extruded aluminum barrel includes sensor grooves on both sides, and because this model includes a magnet (-S), it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. The generous 100 mm adjustment range is mechanically managed by an external stopper screw at the retract end, which works alongside the standard 36 mm air cushions to decelerate the load.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-100S Is Used
Variable End-Stop Positioning
Ideal for assembly stations where the exact retract position must be fine-tuned on the fly, using the 100 mm adjustment window to accommodate varying part sizes without disassembling the machinery.
Machine Changeover Setup
Speeds up production line format changes by allowing operators to dial in a new stroke length within the 160-260 mm range via the rear screw, bypassing the need to physically swap cylinders.
Packaging Line Adjustments
Provides the precise physical travel limits needed for packaging equipment processing different carton sizes, using the rear stopper to set the exact retract distance for each product run.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-100S the Right Cylinder?
Choose this SAIJ80X260-100-S when an application demands extreme flexibility in final positioning, as the 100 mm adjuster provides a massive 160-260 mm travel window that eliminates the need for external stop blocks. If you need less adjustability, stepping down to an adjuster code like -50 preserves a longer minimum stroke.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 260 mm stroke, 100 mm adjustment range, G3/8 PT ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR. Because the 260 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 thread handle high torque, but you should still use an external guide to prevent side-load damage on long unsupported travels. Remember that the rear adjuster is a travel stop, not a locking device; this cylinder will not hold a load without live air pressure, so for fail-safe load holding, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ80BX260-100S FAQ
It features a rear external stopper screw that allows you to mechanically shorten the effective stroke by up to 100 mm. This creates a usable travel window of 160 to 260 mm, letting you fine-tune the end position at commissioning without adding external stops or changing the cylinder.
At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
