About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-50
The AirTAC SAIJ200X260-50 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 50 mm for a precise 210-260 mm usable window. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it ideal for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, though this specific configuration omits the magnet, meaning position sensing via CMSE or DMSE switches is not enabled out of the box.
This model features a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage high kinetic energy during deceleration. The rear stopper mechanism acts solely as a travel end-position tuner for commissioning and product changeovers; it is not a mechanical lock and cannot hold a load without live air pressure. For load-holding requirements without continuous air, an external pilot-operated check valve or a related AirTAC type like SAIL or BSAI should be specified instead.

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 SAIJ200X260-50 Is Used
Heavy-Duty Pressing
Fine-tune the 210-260 mm pressing depth during machine setup to accommodate different material thicknesses without swapping out the entire cylinder.
Product Changeover
Quickly adjust the rear stopper on a production line to handle new product sizes, reducing downtime and eliminating the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-50 the Right Cylinder?
Selecting the SAIJ200X260-50 is optimal when your machinery requires extreme force alongside variable end-stop positioning, such as pressing or heavy clamping stations where the exact travel endpoint needs on-the-fly tuning. Conversely, if you need fixed travel without adjustment, the standard SAI series is a simpler alternative. This cylinder uses a PT tapered port thread and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because this cylinder handles substantial loads over a 260 mm stroke, the 40 mm rod and M36x2 thread provide excellent rigidity against side loads, though an external guide is still recommended for any unsupported heavy payloads. Operating speed ranges from 30-500 mm/s. When replacing an ISO 15552 cylinder, match the 200 mm bore, 260 mm stroke, 50 mm adjustment range, PT port type, and the chosen mounting kit to ensure seamless dimensional interchangeability.
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 SAIJ200X260-50 FAQ
At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm from the nominal 260 mm, creating a usable travel window of 210-260 mm. This stopper only tunes the end position for setup and does not lock or hold the load without continuous air pressure.
