About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-20S
The AirTAC SAIJ100X260-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 240 to 260 mm, allowing you to dial back the nominal 260 mm stroke by up to 20 mm during commissioning without adding external stops. Delivering 7068N of push force at 0.9 MPa, it handles heavy positioning tasks with ease.
This model includes a -S magnet for use with AirTAC CMSE reed and DMSE solid-state sensors, which mount directly into the dual-sided sensor grooves on the extruded aluminum barrel. The M20x1.5 piston rod and 25 mm rod diameter provide robust resistance to side loads, while the PT tapered port threads ensure a secure, leak-free pneumatic connection at the G1/2 ports.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-20S Is Used
Variable End-Stop Forming
Dial in the exact 240 to 260 mm travel window for pressing or forming stations that process multiple material thicknesses without swapping out the cylinder.
Machine Changeover Setup
Quickly fine-tune the rear stopper during product size transitions on a conveyor line, saving setup time and eliminating the need for external mechanical stops.
Heavy-Duty Positioning
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or tooling bases into precise final positions, adjusting the end-point on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-20S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires high thrust (up to 801 kgf at 1.0 MPa) alongside variable end-position tuning. If you need less force, stepping down to the 80 mm bore yields 4523N of push force at 0.9 MPa. The adjustable rear stopper is ideal for machine setups requiring frequent product-size changeovers, acting purely as a travel end-stop and deceleration device, not a lock. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 260 mm stroke, 20 mm adjustment range, PT port threads, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is 260 mm, ensure an external guide is used to support long unsupported loads and prevent rod 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 SAIJ100 Adjustable Cylinder SAIJ100X260-20S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068N and a pull force of 3681N. The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 260 mm down to 240 mm. This creates a 20 mm adjustable window for fine-tuning the end position at commissioning, but it acts only as a stop and does not hold the load without live air.
