Airtac SAIJ200 Adjustable Cylinder SAIJ200X35-20
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X35-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 35mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X35-20
The AirTAC SAIJ200X35-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 15 to 35 mm, allowing you to dial back the 35 mm nominal stroke by up to 20 mm during commissioning.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread and a G3/4 PT port. The variable air cushions at both ends decelerate the heavy 200 mm piston, but the rear adjuster acts strictly as a travel stop. It cannot hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series.

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 SAIJ200X35-20 Is Used
Heavy Press Fine-Tuning
Dial in the exact 15-35 mm pressing distance during machine setup to accommodate material thickness variations without replacing hardware.
Product Changeover
Quickly adjust the end-stop position on a packaging line when switching to a different product size, relying on the 20 mm trim range.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X35-20 the Right Cylinder?
The 20 mm adjustment range is ideal for fine-tuning the retract end-position on product changeovers without swapping the cylinder or adding external stops. If your process requires holding a load statically without continuous air, you must use an external pilot-operated check valve or switch to a SAIL (air-released lock) cylinder, as the SAIJ adjuster is not a locking mechanism.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 35 mm stroke, G3/4 port, PT thread, and standard carbon steel rod. Because the stroke is short, side-load risks are minimal, but the heavy mass still necessitates secure mounting using the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) without FB, CA, CB, or CR brackets. No magnet is specified, so position sensing via CMSE or DMSE sensors is not supported on this base unit.
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 SAIJ200X35-20 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 35 mm nominal stroke by up to 20 mm, creating a usable travel window of 15 to 35 mm. It only sets the end position and does not lock the load without live air pressure.
