About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-40S
The AirTAC SAIJ200X290-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N at 0.5 MPa and reaching 21991 N at 0.7 MPa. The integrated -S magnet supports position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves.
This specific SKU provides a 290 mm nominal stroke that can be dialed back by up to 40 mm, creating a 250-290 mm usable travel window. The PT tapered port and M36x2 rod thread match the heavy-duty 200 mm bore class. The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning; it does 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 SAIJ200X290-40S Is Used
Heavy Press Tuning
Dial in the exact 250-290 mm end position for large assembly presses during commissioning without machining custom spacers.
Product Changeover
Adjust the stroke up to 40 mm to accommodate different large product sizes on an automated line, reducing setup time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-40S the Right Cylinder?
Choose this 200 mm bore adjustable-stroke model when a machine build requires exact end-position tuning without adding external stops or swapping cylinders. Because this SKU features a 290 mm stroke, the 40 mm adjustment window is ideal for accommodating product size changes on a line.
For load-holding without continuous air pressure, note that the rear adjuster is a travel stop, not a lock; you should specify an AirTAC SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). With a 290 mm stroke, the heavy 40 mm carbon steel rod handles high side loads, but an external guide is still recommended for unsupported loads.
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 SAIJ200X290-40S FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 290 mm nominal stroke by up to 40 mm, resulting in a 250-290 mm usable travel window. It is a stop, not a lock, and requires live air to hold the load.
