About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-40S
The AirTAC SAIJ200X260-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 260 mm travel by up to 40 mm. This yields a usable end-position window of 220 to 260 mm, allowing precise calibration at commissioning without adding external stops. As the largest bore in the series, it delivers massive thrust, pushing with 15708 N and pulling with 15080 N at a 0.5 MPa operating pressure.
This unit features a carbon steel piston rod and PT tapered G3/4 ports. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports position feedback via AirTAC CMSE reed or DMSE electronic solid-state switches. The variable air cushions at both ends decelerate the heavy load, but remember the adjuster acts only as a travel stop and will not hold the load without live air pressure.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X260-40S Is Used
Heavy Pressing Calibration
Dial in the exact 220 to 260 mm end position during heavy pressing operations without swapping cylinders or repositioning external mechanical stops.
Product Changeover
Quickly adjust the rear stopper by up to 40 mm to accommodate new product sizes on the line, saving downtime on the factory floor.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-40S the Right Cylinder?
The 40 mm adjustment range is ideal for fine-tuning the end stop during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. For load-holding without continuous air supply, this cylinder will not suffice; you must look to the SAIL or BSAI locking series instead.
When replacing an ISO 15552 cylinder, match these exact attributes: 200 mm bore, 260 mm nominal stroke, 40 mm adjustment, PT G3/4 port thread, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although 260 mm is below the 1500 mm maximum standard stroke for this bore, the massive 40 mm rod and high forces mean an external guide is recommended if side loads are present.
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 SAIJ200 Adjustable Cylinder SAIJ200X260-40S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the 260 mm nominal length by up to 40 mm, creating a usable travel window of 220 to 260 mm for precise end-position tuning.
